Replace a Cylinder Head Gasket Yourself and do it RIGHT! Part 1

[@will305t]

You're nothing but the best. A lot of people out there are looking for a quick fix. But you like to do it the right way. By finding out what caused the problem in the first place. Whatever you do don't stop what you're doing it will pay off in the long run.

[@abelrodriguez2525]

I started 15minutes working on pick your parts and then getting car scanner and lean and search on you tube for tools and how to work with engine, so far I work on a dismantling auto job and almost all the time they work with head cylinders I'm a driver and once in a while I watch and this you tube teacher explain everything in the books. Thank you it's being almost a year and I learn a lot thank u for this videos

[@helookalikaman79]

Watching the dismantling and the long boring video of switching sockets for tons of bolts etc is how some people learn (like me) give a book on how to dismantle something, it isn't going to end well, Watching someone actually doing the work, helps and teaches us how to do the job....

[@jakobmc2788]

Agree 100% Knowing what order to remove what has really helped me along the way with many repairs.

It's totally bizarre that he would not even stop to consider the whole point of making a vehicle maintenance video

[@stevenmotchan2048]

Masters at a craft don't always make the best teachers. Especially not for beginners. Should Eddie Van Halen teach beginners how to tune a guitar or teach advanced players how to tap, shred and tremolo? Everyone needs to learn how to tune their guitar but anyone can teach that.

[@Msleelee9487]

yea I would watch it from start to finish how to take an engine apart and put it back together that would be awesome. That's how I learn too !

[@robertpreston2352]

True and needed you should also loosen bolts in reverse order of torque specs. outside first working to center.

[@labradormcgraw2409]

This guy simply doesn't get nearly the recognition he deserves. Such a great mind coupled with a natural talent for teaching. For diagnosis tutorials, there is no one else on KZbin who even comes close.

[@978eric3]

Youre a great person. I know a few mechanics like you who do my car work for me im glad that theres still people out there like you.

[@olubukolafamuyiwa6576]

The message from every video is about having a deeper understanding about whatever it is that your doing. This makes me appreciate this craft and put more time into learning it.

[@chrisvill54]

The most interesting thing I learned about your video is that head gaskets do not just go bad. Something causes the car to over heat and that causes the gasket to go bad. Which totally makes sense because the only two friends I had that had this problem ended up with the same problem again after replacing the head gasket by their mechanics. most mechanics just replace the gasket and don't really check for what caused the problem.

[@SchrodingersBox]

If you take just one thing away after watching this video, that would by far be the most important one. I cannot even count how many times I have seen the same thing happen. I knew a guy who actually had been through this twice and then when he finally brought the car to me I pointed out the fan switch failure causing him to keep overheating in the first place.

[@fcgodftw]

While I agree that most of the time, headgasket problems come down to driver error (water pump failure, lack of coolant, rotten radiator or leaks in the circuit, etc), sometimes that's not the case. I have a Lexus IS220d, the only diesel Lexus has ever produced. It has the infamous 2.2L 2AD-FHV Toyota engine very prone to headgasket problems It's like 99% certain if you have this engine, it will at some point in it's life show headgasket problem symptoms... Well let me tell you my story, mine has recently started showing these problems. Basically since 10k Km ago (my car has 191K Km) it started spitting coolant through a hose on the coolant reservoir. It doesn't seem to be burning coolant since there's no apparent white smoke nor power decrease and also there's no oil on the coolant nor coolant on the oil. I haven't done a leak test but it's apparent there's compression going into the coolant circuit which causes the coolant to be spat out. I've been checking it daily and have basically used 0,5L to 1L of coolant in the last 10 000 Km. The car has 100% never overheated nor been driven above normal temps and if you search Lexus forums you'll understand that sometimes, it's just shitty engineering design that causes these flaws. Literaly Lexus replaced these engines through an extended 7 year 100k miles warranty due to how shitty the engine was yet some people had the same issue later on in their life. Same goes for the N47 2L BMW Diesel engine, very prone to snapping the timming chain due to a fault in the hydraulic tensioner that's supposed to last a lifetime. (wasn't sold in the US).

This is a great video! This guy doesn't pretend to be a master mechanic because he doesn't need to be. He's a scientist who works methodically and precisely to get the diagnosis right first time. This guy truly knows his stuff and conveys the findings really well. We can all learn so much from watching this channel.

[@SirBroheem]

I cant explain how much this helped me. Going to be replacing a 2002 Mustang GT and making some mods to it. I knew there was more to the game than most other videos were missing.. Really appreciate the level of detail you take and elaboration on most things. I feel confident in doing the gasket now.

[@mtdewandal]

Recently did a head gasket on changing out a cylinder head on my car and used a lot of the knowledge you passed. Thanks for the info, helped me out a lot.

[@jojo123469]

Your time, effort and expertise are priceless..my 15 year old Honda head gasket fixed and rockin again . Cause of blown gasket, thanks to you for finding the reason for the issue, failed radiator. Replaced radiator replaced head gasket. all ok thank you. Canada

Well, 71 years and I still learnt something new. Thankyou.

[@djd829]

I'm a software developer, who also works on my own vehicles. Never saw you before, but your troubleshooting approach is spot on. It doesn't matter what you do, *ROOT CAUSE IS KING*. This applies everywhere. You rarely get to it on a hunch. It always comes from a very thoughtful chain of processes that could go wrong to boil down to a singular cause. I live by this. Very smart dude and I wish I could hire him to work on my cars. These guys are a rarity in the auto repair industry.

[@SchrodingersBox]

Thanks man!! It is much like software development. I'm pretty sure when you have a software bug you don't start just randomly changing code- you systematically find the error, verify you found it, make the correction, and then test it.

[@djd8297]

Yes sir. We have too many repair people around here who "work on cars" because they used to fix the lawnmower when they were little, and demonstrate only basic understanding of how things work. Really sad.

[@adinsx88]

This. I am a physician that dabbles in auto mechanics. The more I learn about auto work, the more I am constantly amazed at the similarities between the two fields. Watched a few of his videos now, and his scientific approach is much appreciated.

[@StilettoSniper]

I watch everyone else's KZbin videos to get a general idea of what's involved. Then I watch the videos on this channel (and your Quantum Mechanix), ScannerDanner and a few select others to understand how to properly diagnose, confirm and perform the job correctly before I even consider attempting it. Great job Matt, your dedication to the scientific method and actually addressing the root cause of problems (not just the symptoms) is greatly appreciated by those who are capable of doing so.

[@rsage_]

You're absolutely right about finding a reason as to why the head gasket failed. Except one: Subaru engines. Those head gaskets go out simply because of faulty craftsmanship in the gaskets. Thanks for the great video.

[@Autofixpals]

+Rodrigo Sagebin yup engineering flaw on subarus part.

[@korbenelements]

Yep same thing with the 94 Mustang 3.8L :(

[@Autofixpals]

I know that for a fact about the 3.8 Mustang in the 90s. I was working for ford Lincoln Mercury (professionally) in the late 90's when they had a recall on all those 3.8l headgaskets. I did quite a few of them. HGs do fail at no fault of the driver.

[@korbenelements]

+Auto Fix Pal yeah after having the dealership change my headgaskets for $2,000 didn't even last 25K. before it blew so I ended up doing myself and so far it's been about 50K. Instead of using the Ford headgasket I want with felpro. I'm about to add an oil cooler to help keep the heat down. Do you thing an oil cooler would help?

[@Autofixpals]

You will be fine without an oil cooler.

[@keclark4]

Excellent video. I was able to determine a solid logical approach to solving my specific head gasket situation for my 2000 Chevy Silverado 5.3L. In my case performing the chemical and compression tests showed non-positive results for a blown head gasket, but was still helpful in determining the nature and extent of the coolant leak. I simply had coolant leaking externally out of the head gasket from a coolant jacket, which gave me some time to plan the proper fix and work around with other modes of transportation. I ran into a few snags when performing the job as can be expected, but feel confident that everything was done right on my end. The truck has been fixed now for over a month and still running great with no leaks. Thanks for the help! Oh and I forgot to mention this was all done spending under half the estimated minimum cost to fix. Plus, I get to keep all the new tools.

[@SchrodingersBox]

keclark4 Nice job and great diagnosis! The money you saved by diagnosing it correctly probably paid for the tools so consider those payment for your effort!

[@macknumber9]

What was the repair?

[@Yotraj]

Nice video... just an old gearhead myself... I am though Certified Class A Gas & Diesel with around 40 years of experience.... a couple of comments. You use a "thread chaser"... well that's all well and good but what IS a thread chaser? On diesels the compression ratio is much, much higher than a gas engine so cleaning out those head bolt holes is of even greater importance. I would imagine that most readers don't understand that there are different "thread chasers", or what they perceive to be "thread chasers"... the proper "Tap" (to use the correct term) to use is a "bottoming tap". A standard tap has a tapered head, tapered to help in creating the new thread. But at the bottom of the hole it doesn't cut complete threads. They are angled towards the center. But a bottoming tap is has no taper and is made to ensure that threads are cut completely all the way to the bottom of the hole. On another note... I had a friend who used to race motorcycles on the roundy round circuit. He would build his engines without gaskets! I wouldn't recommend this for head gaskets... but the rest of the engine he would lay out a piece of glass and then spend hours flattening out his engine parts by rotating them around on the glass with valve lapping compound until they actually were flat! Hence, no leaks and no gaskets! On diesels the head bolts stretch! I always replaced them no matter what. On gas engines I've always re-used the bolts if they passed a visual inspection... I've done well over 100 heads on cars, trucks, heavy and light equipment and high horsepower 60's, 70's and 80's era Hot Rods. bikes and boats and I've never had a problem at all. Take that as you may. For anybody who might be reading this... I cannot overemphasize the importance, as did the creator of this video, of cleanliness. Do it right the first time and you'll save yourself a world of grief. This is one of the best KZbin mechanic video's I've seen... and I've seen a bunch.

[@christopherjoseph5018]

No body gives a shit about diesel unless they drive one. Looks like this guy is talking about gasoline engines. Take your experience and share with people who post diesel videos. This video is about gasoline engines. Yeah got it the average Joe may not understand cuts but you are applying your knowledge incorrectly. If you can afford a diesel then you can most likely afford to take it to a shop.

If you follow the advice given in the video you will have the best possible chance of a successful repair. I just replaced the head and gasket/s on my 1997 BMW 318is. I'm no mechanic but it started - first time!. One of the most important tips I took onboard is to make sure everything is CLEAN! Secondly make sure you have the RIGHT TOOLS! I had to buy a torque wrench and a Torx socket. Thirdly TAKE YOUR TIME! I did the job over 5 days. Matt's presentation style is spot on. Not too in-depth but all the critical information is spelt out in reasonably simple terms. Forget the 'Pro's' on the forums. This is the place to find the PROPER answers. WELL DONE MATT!

This has been a good series, I think because of your science background. Most other videos of this topic don't spend so much time on critical diagnostics. I didn't know about fire rings, either. It's too bad TTY bolts don't have a universal label. Can you explain the process of magneflux to find occult cracks in a block?

[@thephotoperson]

When I first bought my 2004 Volvo S40 I took it to an auto shop in San Diego to have it inspected before I bought it. They said it was fine, but the main crankshaft seal was leaking and it would need to be replaced or I would need to add oil a lot. I decided to buy it and over 2 years they did many repairs to it including new struts, new timing belt, and plenty of alignments. I noticed that the same problems kept coming up and at this point I had enough and took it to another shop. It took them 2 hours to inspect the car and gave me a grocery list of what was wrong - including the failure of the head gasket. They said with the amount of encrusted oil and dirt its obvious it had been leaking for years, probably before I bought the car. The first auto shop most likely knew this and chose to keep silent because they saw it as an investment on their part. I just wanted to say thank you for being an honest mechanic! It's so hard to find mechanics who just want to help instead of profit. I, myself, am now studying automotive mechanics with the goal of working with cars long enough to consider engineering. But I promise any car I work on until then will be towards the best interest of the customer and not the shop. Thanks again!

[@1984juant]

Really inspired to DO things RIGHT.

[@donaldfafard]

if nothing else it's called taking PRIDE in what you do. something most of the younger generation doesn't understand.

[@donaldfafard]

***** that's great but they aren't mutually exclusive, you can be both.

[@donaldfafard]

***** first of all you mean 'night' and day. secondly, camp counselors instill pride AND responsibility in their kids for a reason. pride is not a bad thing unless you bastardize the meaning. Pride and Responsibility Pride and responsibility are two qualities Camp Winnebago counselors role model to the campers in their bunk. Each morning campers make their beds and clean and sweep out their living space. This is a time of community building where counselors, through their actions and words, role model the importance of taking pride in keeping a clean living area. Because campers participate along with the rest of the campers in their bunk, they develop a sense of responsibility in being a contributing member of their living community. - See more at: campwinnebago.com/2014/11/06/pride-and-responsibility/#sthash.LaXehc8u.dpuf

[@SchrodingersBox]

***** Now now guys- FWIW, I actually see a very strong connection (but not necessitation) between responsibility and pride. In fact, one of the keys to pride in yourself and your work is having (and taking) individual responsibility, This can often be made very evident with the younger generation- even teenagers- in an experiment you can try yourself if you have teenagers. Tell your kid you will give him 20 bucks to mow the lawn. Then about 20 minutes later look at the half-asses job he'll probably have done. But sit with him and discuss you are giving him the "responsibility" of mowing the lawn- more often than not there will be a dramatic difference in the effort because most teenagers often want to prove they can handle responsibility and will take pride in showing the effects. Most everyone works harder on their own projects than on someone else's- the higher sense of responsibility generates more pride in the work. But not always- many people just plain have no work ethic and/or have a sense of entitlement- and therein the experiment fails. Using my example, you would think people on welfare would be desperate to get off of it but alas, generations continue to subsist off it as a lifestyle. I actually think this phenomenon is as common in the younger generation (who either had everything handed to them and never experienced taking responsibility or they have unrealistic expectations of what is required to be successful) as it is in the older generation (who feel they spent a lifetime contributing to the society and now want their "dues" or at least think there should be a default of respect and acknowledgement for simply having lived longer).

[@VirtualPlayer0187]

Not all of us are mechanically incline. It really does help a lot when you can see what parts need to be remove. I did my first head gasket and i had not a single clue what to remove or where to start. That's why they get so many views because you are helping the community. From special tools to the timing all learned from ppl explaining and the how, where and what is required on the job your doing.

[@wsvitak]

By the way.....I learned a lot from your video. I can tell by the way u performed your work that you are an experienced mechanic. Most people would say hey I have a bad head gasket and need it repaired and never think twice about the other damage that could be caused by the gasket and the defective parts that caused the gasket to go bad. I was watching your vid because I was contemplating on buying a van from my job that has a bad head gasket and realized that it could be way more trouble than just replacing the gasket and it wouldn't be known until you start pulling things apart and testing them. Now that I've seen it done and know what issues could arise I think I'm going to pass on the purchase. So thanks again for the vid it helped me tremendously.

[@SchrodingersBox]

Thanks WSVitak. I am not actually an experienced mechanic- more of a DIY who had lots of experiences. But either way I think you made a very wise decision. I have seen many, many, many many many cars that needed "just a head gasket" and as you learned, by definition, they ALWAYS will necessarily need more than just a head gasket and usually they need more than a cylinder head too. Just the coolant running through the oil for who knows how long is a major consideration for the bottom end damage that may have been done. Not that you can't get a great steal on a car with a blown head gasket that you repair yourself- but you need to understand you are gambling with a minimum weekend of time and minimum $300 dollars up to over a thousand dollars or even a potential blown engine that you only discover after you did the weekend and $300 (for example engine doesn't run right after resurfacing the cylinder head and compression test shows it's because it has a worn piston ring that you couldn't diagnose earlier because the compression was low due to the head gasket leak).

Don't use sandpaper! Use a Stanley blade and take your time.

[@SchrodingersBox]

WHy would you not use sandpaper? Especially on an aluminum head- I'd NEVER use a blade on aluminum!

[@22muaythaiguy]

Schrodingers Box The aluminum oxide could get into the engine and damage cylinder walls, bearings etc. Big no no in factory service info. Voids warranty on some factory vehicles if the warranty manager detects swirls etc from using anything with an abrasive like sandpaper and techs job could be on the line if he did. I am always on the look out for a good effective method with minimum chance of oxide contamination.

[@SchrodingersBox]

That makes no sense at all. A cylinder honing would be way worse for contaminants. Proper cleaning after the procedure is necessary regardless but aluminum oxide contamination would be the result of improper cleaning and flushing. And voided warranty on factory vehicle after a rebuild? Hardly makes sense to me.

[@22muaythaiguy]

Right, but we are not talking about an engine overhaul where everything is completely apart and cleaned like a cylinder honing. If the head is removed and you clean it with sand paper, it would be reasonable to assume that you could clean most of the grit off of it before re assembly. What is your method of eliminating that contamination from the rings, crankcase and cooling system of the block side ? Not saying I dis agree with sandpaper. Trying to bring light to the risks involved and reduction of contamination.

Holy shit, this was a good video.

[@ThaSatelliteGuy]

I have experience with NDT and as a mechanic so this is a lil me-specific, but it's not complicated... The last head gasket job I did was a 3400 in a 04 Impala. I knew where the problem was already from my scanner and the look of the chamber. (#6) I glued some sandpaper to a large slab of glass and resurfaced the heads myself. I was skeptical about it until I got to the second head, (246) and saw the low spot in the sanding around cyl 6, and it took a LONG time to sand until it FINALLY sanded out. After that, I had way more confidence. I also was able to take the heads to a friends machine shop (not an engine type shop) and was able to check them for cracks using flourescent dye penetrent before doing any work to them. Also did the normal leak testing and seals. So, ya, if you have the right experience, and some common sense, you CAN, sometimes, avoid the machine shop.

[@KaliBlaz]

this is everything but how to do it yourself..

[@SchrodingersBox]

Come again?

[@KaliBlaz]

Schrodingers Box your videos are with no doubt excellent and there are a lot of information to take note of, but it is not for your average DIY'er who owns few screw drivers and a 40 piece wrench set. it is more for advanced guys who got a real home shop and all the tools out there, and if you need to take the head to a machine shop to get it fixed then is no longer a DIY project. no offence intended.

[@SchrodingersBox]

certified30 How do you propose a DIY doesd a major, major repair like this without having proper tools? You CAN do this yourself with the proper tools and knowhow. You can't DIY changing a light switch unless you have a screwdriver and pair of pliers. My responsibility in a tutorial video is to show how to do the job, not how to do it without minimum required tools. BTW what tools do I use that a DIY wouldn't have easy access to anyway? This example is done with basic hand tools easily available anywhere.

[@KaliBlaz]

Schrodingers Box what I mean to say is a head gasket job is not a an oil change. it takes some extended mechanics knowledge and access lots of privileged technical info that your regular Joe most likely does not have access to, at the beginning of your video you mentioned that you don't understand how a removing bolts video gets 300K views well it because most guys watching KZbin videos are looking to see what bolts to remove and a step by step removal procedures of a cylinder head not a video of a cylinder head already removed and opened up in pieces, what is a given to you is not necessary a given to everybody, that's why channels like scotty Kilmer, Eric the car guy ...etc are successful channels don't get me wrong you got about 14000 subscribers for a reason but you are more into advanced diagnostic stuff.

[@SchrodingersBox]

certified30 Not sure I follow your logic... at all. You say this video does not show you how to replace a cylinder head yourself because it doesn't show how to replace it if you don't have the right tools. Then it's because it doesn't show you how to remove every single bolt which is what beginners need. Then you say replacing a cylinder head is not a job for a beginner.... I really don't know what you are trying to say bro. Whatever- I'm leaving it as it is. It's the most comprehensive video on the subject I've seen on you tube and if it fails because I don't show a beginner how to do it with a butterknife and a hacksaw, so be it.

[@KubotaKid]

Outstanding. About to work on a 05 1.8 Sentra. Now you can get a dye penetrant kit and use it to find cracks you normally cannot see with the bare eye. I use it checking welds all the time on boiler flanges and such. Keep up the good work.

Thanks for the very detailed video and advice! I’ve always wondered how mechanics do this! I’m about to tear down an old 5.7L V8. This video is very helpful for me!

[@sahmadi1000]

I will follow you because the way you reason and the way you support what you say and you do. Thank you for all that you do for us.

[@SchrodingersBox]

+sahmadi1000 Thanks I won't let you down!

[@KeithS-ud8ji]

Other videos of guys ratcheting bolts out and stuff can help you make sure you have the right tools. However, these videos provide you with an EDUCATION and thorough understanding of when, how, what and why. I recommend checking here first to learn what you need to do. Then if you want, you can go watch a video on what bolts you need to turn. Great work on these videos!

[@SchrodingersBox]

That’s the philosophy!!!!

[@briansydnes1711]

Good video. GM replaced my pistons and rings under a special warranty due to oil consumption. While the head was off I had the head cleaned and inspected by a machine shop. They found the exhaust valves pitted. They re-ground the valves and seats, installed new valve stem seals and tested for vacuum leaks. Comments: never use a wirewheel or other abrasives on the head or block, especially aluminum. GM has a TSB on using only plastic scrapers and solvent to clean surface. My tech said he knows of a tech that was fired for using an abrasive wheel on these surfaces. For intake and exhaust, not a big deal. Don't use a tappered thread chase because is will not clean the bottom most threads. You can use a clean head bolt and run it in and out a few times, cleaning it each time.

[@philippeantonietti]

thank you very much for the video ! at the moment im at university so i cant afford a mechanic professional, with this video i was able to save my 17years old vw golf, it will keep me going until end of uni best regards many thanks again

[@nicholaslynch7651]

I'm about 4 minutes into this guy's video never seen him before. omg thank u for all this side informstion. this is why I watch do many videos and ur condensed ING it for us . ur a beast msn

[@zurgboy07]

This is very informative I was planning to DIY SLAP A HEADGASKET AND BE DONE WITH IT but this has enlightened me to prep for more stuff to look out before doing such a thing and avoiding making mistakes.

[@SchrodingersBox]

Yes do not just slap in a head gasket or You WILL be doing the job over again probably immediately!!

[@ampload]

spelunkard I totally agree with you 100% I have been watching Schrodinger a long time and hes always spot on. He goes into fine detail always many of the others are just parts changers and dont goe into deep diagnostics like Schrodinger does... maybe the haters are just jealous who knows this world has all kinds.. hes awesome and my #1 goto guy... thumbs up

[@PatrickBaptist]

Great video chief, thanks for your time. Doing my first rebuild on a 7.3 PSD. A person is dim if they reuse head bolts, even on a lawn mower, I broke one off in a mower once trying to reuse it.

[@chriswerner8968]

N

[@spankthemonkey3437]

Patrick Baptist hey I used to reuse head bolts on my 5 hp Briggs and Stratton go-kart engine never used a torque wrench for the head bolts and even used the same gasket. The only place I used torque wrench was the billet connecting rod

[@DIYAutoHomeschool]

Excellent video sir. I agree with you on the head bolt thought process. Simply put, if I (or whoever is paying me to do the work) is putting the money into diagnosing a concern, removing a cylinder head, troubleshooting the head, and putting it all back together, there is no sense in risking that whole job over again because of a head bolt set. Anytime a head comes off in my shop, new bolts go in.

[@christaylor9112]

A very well thought video, plus you explain the science behind every step as well. Watching this leaves me in awe of you great mechanics out there.

[@randomugliness1238]

I've lost track of how many times I've watched this video. My first cylinder head removal was about 5 years ago.. Had absolutely no compression on cylinder 3 on my 3.5L Chevy engine. This thing was literally reading zero. I had brought it to a shop for a lower intake manifold gasket and when the car was returned to me it had a dead miss. After fighting with the shop, they would not look at it and insisted they didn't do anything wrong... Well they did. One of their techs swapped the intake and exhaust push-rods while reassembling the engine, causing a valve, and the guide in the head, to bend violently. I replaced the head with a used head and it was good to go. If I could have proved at the time that they were the ones who caused the head to fail, I would have pursued legal action.

[@darrylgundesen619]

I open my heads and all coolant ports were blocked.... I didn't open due to low compression but did it for overheating issues. Excellent video. Ty.

[@dirt3800]

"They have turned more pages than wrenches." It has never been said better. Great video.

[@trombahonker]

I really appreciate how articulate this gent is!

[@dre.supreme]

This man here def has a spot in heaven. Thank GOD for you my guy.❤

[@williamjones6896]

Really nice video and thanks for the knowledge! I saw this prior to starting my Jeeps head gasket. I took the advice and had the heads checked at the shop and sure as "ish" the head was cracked! This video saved me a whole lot more time!

[@SchrodingersBox]

William Jones Excellent job by you and the shop. Most people would not have realized that was the cause of the problem until after they replaced the gasket.... Then they do it all over again. and sometimes again.

[@tamaragee530]

I'm actually in the process of replacing my head gasket so I'm glad to have came across your video. I Love the way you thoroughly explain things! Oh and love the "nothing like good head" surface comment! Liked and subscribed!

[@SchrodingersBox]

Tamara Gee Hahaha, Thanks Tam, I am glad you found the channel!

[@carlosmelendez6481]

I can tell you worked hard to be where your at now, keep the videos coming

[@mikemilliorn4687]

I love the hands on common sense approach to this repair! have a 2003 Dodge Stratus with the G engine in it and I replaced it with a used one with less miles the mechanic said the head had been replaced. My question is all of a sudden it is overheating. I have replaced the radiator, hoses, thermostat, the fans all work and I think I have oil in the fluid..I guess the Head Gasket is next repair? What do you think?

[@SchrodingersBox]

I would see my video series "12 ways of how to test a head gasket" and this will help you definitely find if a head or gasket issue is the cause.

[@mikemilliorn4687]

Ok thanks I will look at it right a way and go from there. I will let you know what I find out!

[@Snailmailtrucker]

I have a 91 Toyota Pickup truck 22re with water in the oil...I was already in the process of ripping the head off when my 20 year old son told me to wait after we did a Compression test. 165 Lbs. in Number 1 and 170 lbs. in all the others. Never even considered Intake Manifold...I will watch the rest of your Video. Thanks Liked/Subscribed

[@SchrodingersBox]

Yep- with those numbers a cylinder head is contraindicated as the issue.

[@opgkoyote7989]

early 03 mustang cobra's have head gasket issues, well some of them do. with my luck mine will blow very soon and i haven't even hit 15,000 miles yet. this video definitely helped.

[@pauldunlap4303]

Thanks for the great video. Watched both parts twice, and felt pretty confident going into what I thought was going to be a head gasket replacement.... but I got lucky and during the tear-down I found a single bolt missing on the lower intake manifold.

[@donhiebert3750]

Excellent video. I'd suggest also inverting the cylinder head on the bench and pouring some gasoline into each opening to test for leaks. Also, this test can be used in cylinder/piston gap situations. That might indicate more work to be done, even if not related to the overheat condition. Occasionally, cracks or gaps, either in the block or the head will be found in this way.

[@UniqueTouch]

Thank you Sincerely for your help and prompt answers sir. IT'S a Blessing that I found you and your expert advice rte now.. When I need it the most. Keep up the great work Sir. You are truly helping ppl and Christians as well my friend! Take care! Sincerely, Angelo M.

[@TK42138]

Spot on with your observation regarding the age old argument of 'new or reuse head bolts'. How I see it is that the old bolts will have gone through three main stress patterns; tension, torsional and thermal. Basically a set of new bolts is going to be a damn site cheaper than having to do the whole job again when the old bolts fail to clamp the head to the block correctly. Last thing any garage wants is the customer returning with leaking HG caused by old bolts.

[@cameronstolhand7149]

Thank you so much for making this video. I think you saved my whole project by providing advice that is not in the manual.

[@SchrodingersBox]

Most people do this job more than once because they don't think in terms of "etiology'.

[@fernando13e]

Excellent video man really informative, im going to be honest, the first time i watched one of your videos i was kinda skeptical, mostly because of the "Haynes manual" guys that were religiously yelling "No way man! that's not the correct way to do that stuff!" in fact i was somehow doubtful because in some sort of way Haynes manuals are pretty useful, but just for the basics, that's it, but in the end i learned from you the logical way to solve problems.. here in my country mechanics are known as part swappers and they dont really do ANYTHING to solve any issue with a car.. Another thing i wanted to tell you is that you mention that the head bolts that were used to join the warped cylinder head with the block cannot be reused because of the mechanical stress resulting from the warping of the hed and the stretching they suffer, you are absolutely right on that and not just only because of that but also those bolts had been heat cycled many times!. Keep it up man!.

[@SchrodingersBox]

+fernando13e Thanks man good feedback!!!

[@nickg1387]

This is very helpful to me because i have been considering one of the mamy Craigslist cars going for cheap because of a "blown head gasket" This helped me see that is an awfully vauge and possibly misleading diagnosis. Thank you.

[@SchrodingersBox]

Indeed I started this hobby doing exactly that. Most of the cars had much, much worse than blown head gasket, they needed bottom end rebuild. One actually just had a cracked spark plug- got lucky there. But overwhelmingly, most cars needed considerably more expensive repair. On average For a 8-10 year old car that I bought for under $800, I would spend about $800 to get the cars in perfect running condition. At average sale price of $3500 it wasn't bad for a couple weekends' work.

[@kaktusjack1033]

Awesome video / tutorial. Nice to see an advanced DIY video with some in depth analysis of the issue. I do agree to some point that it sometimes does not make sense to record the whole process of removing the head and each bolt & hose in the process. Even the description of your channel states - "This channel is for Advanced DIY auto repair" which should imply that the viewer is familiar with some previous automotive repairs. Then again I think there is a need for the channels / videos that go more in depth of the process of removal itself. I guess its something like school. You can't jump to solving differential equations before learning basic calculus (and a lot more stuff before). Anyway big thumbs up for the video.

[@joaquintorres3899]

you do a great job explaining all the details but it is important because for people that don't do it need to know how to remove it just like me I am challenged because I don't know what needs to be removed or how far to go and what tools to use so it's good to see those videos of removing it you do a great job of putting it back together all the explanations are great and easy to follow I like your videos and the knowledge that you carry but knowing how to get to the park or take it off is very important for the do-it-yourselfer

[@Pr0ph3cy-k5z]

I'm sorry, but if you don't know what to remove or how far to go or what tools to use, then digging down to the heads is something you most definitely need to avoid. Pay a mechanic to do the job. On the other hand, you could just dig in and learn from your mistakes..... and a mistake this far in would definitely teach you a hard lesson.

[@davidpeterson6147]

you sir are awesome. I wish all mechanics had your knowledge.

[@AtomicReverend]

I just wanted to commend you on an excellent job. I don't think I could have explained to a customer in better detail how to properly diagnose a head gasket failure. then trying to explain that the failure was just an end result of another issue.

[@dave1135]

Any head gasket job I get, if it's aluminum head, I do a quick check with a straight edge and feeler guage. If I can get a .05 guage under it, it's off to the machine shop. If there's no warp, I pull the valves and check for obvious cracks. If I can't find one, I have the shop check it with their equipment.

[@teamroping-itsafamilything2472]

thanks for giving me this details I’ve been looking for while not frustrating me (nor insulting my intelligence); If I need to be told to pop the hood first, or what tool to use to unbolt… anyone needed that type of info has no business under the hood.

[@Ivan-rs2xt]

[@tonywormer8681]

Excellent presentation and well presented. Never mind the know-it-alls, keep it up!

[@onlyadot]

Hey I like your videos but I did want to answer your question about watching people remove parts. When I started working on cars I basically only knew how to change a tire, I am a visual learner, diagrams, videos and narration with notes is the best way for me to learn. So yes I do like to watch people wrenching their cars on video it helps me understand what I am doing. Now that I am more experienced and am familiar with all parts of the car the wrenching videos aren't as interesting, but they were a HUGE help in teaching me how to work on cars.

[@wsvitak]

Appreciate the vid... The reason a replacement vid gets way more views than a diagnostic vid is becAuse a perso. Takes their vehicle to a mechanic the mechanic says u have a bad water pump and have to pay X amount of dollars. The person either doesn't have enough money or feels they are mechanically inclined enough to do the work themselves. Then we look up a vid to see how a person does it and what troubles that person has come across and how they went about fixing the issue. We can probay do it without a vid, but if someone has done it a can list issues they come across then we can avoid those issues or be prepared for them and expect them when we attempt a repair. I learn everything from youtube and even though I'm mechanically inclined and have performed many repairs I can always learn a thing or too. Nothing worse than someone showing a vid of something they just fixed but having no info on how they did it.

[@SchrodingersBox]

Good point, that makes perfect sense!

[@trealwilliams1563]

Man... I really enjoy watching your videos. After watching all your videos I think that I could top you... Great Teacher 👍

[@TK42138]

Nice work, well explained. Now prepping my Citroen XM 2.1 TD block and head for new headgasket. Monster job on the XM as the engine has to come out to pull the cyl head off. Good job I love working on cars...

[@Joedoriamusic]

I have NO idea how you would have ANY haters, your videos are top notch. Extremely informational and damn near necessary. Would you mind my asking about my latest project - likely blown head gasket on a 1987 Dodge Mini-Ram (Caravan essentially)? It has the Mitsubishi 3.0L 6G72 V6 engine and 3-speed trans, cast iron block w aluminum heads. I'm watching this video again because this is a job I would like to do myself (I maintain all our vehicles, just wish I owned a prof lift!). I use this van to haul my Hammond B3 (organ) for local shows, I have a larger van for touring, etc. Problem just happened recently, I pulled up about a block away from the venue/stage we were playing, and suddenly noticed a stumbling idle (misfire - still kept running though, and ran well when giving it gas) and lots of steady white smoke from tailpipe, my heat in car went from hot to cool eventually (I immediately said, oop there went the head gasket). Thankfully I was close to the show so was able to shut it off before overheating. I could see temp gauge hinting it would go towards getting hotter and hotter so I shut her down. Then take out the Hammond, did show (yep, made the show. Hahah, it was great too!) and setup to have it towed to my home garage. Once I turned the vehicle off however I could not start it when I tested, just a click and no crank, it was dead (suspect coolant in 1 or more cyls). So: Lots of white smoke, sudden stumble/misfire at idle, heat in van went from hot to cool. Also test restart failed, no start. I pulled into a safe space and had her towed to my garage. I'm at the sleuthing part first here to find the what and why. I'm thinking it's just that the HG failed and/or intake gaskets. Worse, aluminum head crack (but not so quick to judge that as i was able to shut down before overheat). I sure hope it's not in the block. It's cast iron and i read that these old engines are pretty tough. I keep reg oil changes, coolant, fuel filters, any and all maintenance religiously. The radiator is pretty new as are the upper and lower hoses. PCV was new and just did the water pump and timing belt as well this past summer. Drove really well, good cooling/heat, then...this. I do see the tan froth under the oil cap (never have had that before) so HG is likely here, but seeing no signs of tan/milky oil on dipstick. I drained what coolant was left in radiator via the drain plug and saw no oil in that (green reg coolant). I will take off lower rad hose and check further though. Can you provide any tips and info on this engine in regard to sleuthing the issue and doing this job on this engine? There's lots of room to work in these old vans, there's so many reasons to keep her going and I will enjoy doing this job actually (NOT a pro of your caliber but have the tools and am damn good with all the vehicles I own). Thanks for any tips, thoughts, on this

[@SchrodingersBox]

I'd have to see what data you have. I can't do anything on a list of symptoms, sorry.

[@Joedoriamusic]

@@SchrodingersBox Understood,realized I was rambling a bit (was in the sleuthing phase). Just meant to ask if you know about these engines and it's % of HG survival if I decide to do myself. Latest update: oil drain showed coolant at bottom (oil on top of that). Gonna pull heads and take a look.

[@stoneyfisher9409]

Very good video.all about the task . this was explained very well I'm amazed. Most of these guys that do diy videos are assume the audience knows things that they know .I don't see that here . once again ty!!

[@shamfirestormdragon5341]

Thanks for the Tip's , I see people troll the net and criticize others for trying to help others, but perhaps if they could turn their negative into something positive maybe they to could humbly help others as well. I'm currently stuck in a jam with my 2005 VW GTi 1.8t with a blown head gasket. I'm not sure what the labor cost alone will cost me, However I'll have to double check as to why it went bad in the first place . So wish me luck and thank again for the info ! Keep up the good work and spread some light on those trolls under their bridges !

Seafoam deep creep also works well for keeping rust away. I discovered this when i was rebuilding an engine and ran out of wd40 late at night but had deep creep on hand.
