Extreme Budget Engine Rebuild-Part 2

Part 1 is here: • Extreme Budget Engine ...
Part 3 is here: • Extreme Budget Engine ...
This part (Part 2) covers camshaft removal and inspection, dissassembly of the bottom end of the engine -removal and inspection of pistons and crankshaft.
You'll soon learn the term "budget engine rebuild" is an oxymoron!

Indeed it's shocking really. Great information in these videos, I would have subscribed. However, instead I'll only return in future if unable to find the info elsewhere. @Schrodingers Box cut out the sarcasm and condescending comments, you lose more than just the "haynes manual jockies" that you're targeting with that language.

I know I am way late to comment on this video but I wanted to say thanks for all the time you put into this. I don't think people realize how fortunate it is for us to be able to reap the knowledge that it took years of experience for you to gain. Out of necessity and want, I know that I will have to do an engine rebuild soon and I appreciate the thoroughness and the dispelling of myths regarding engine rebuilding. It will make this process much easier. You have earned a paid subscriber.

[@MrTatemo]

You shouldn't let the Haines manual jockeys affect you so much. You bring them up over 10 times in this video and it only serves to let them know that they are getting to you. Additionally, as a viewer who is purely interested in what you have to say about the engines, it is distracting when you go off about them again as I am trying to concentrate on your wise words.

[@sureshotmcpro3469]

Uh, excuse me we are scabs not Haynes manual jockeys.

[@hereticxxx9317]

[@comitatus111]

Watching your video reminds me of the time I changed the camshaft on my '72 Pontiac Lemans. It was built in Canada and had, factory installed, a Chevrolet 350 engine. All went well until it was time to set the camshaft timing. Recognizing that it was a Chevrolet engine, I went to my manual and set the timing according to what it said about that particular engine. Well, it would not start. After several hours of sheer frustration...thinking I had really screwed things up, I looked in the manual to see how to set the timing on a Pontiac 350 engine. After resetting the timing the car fired right up and ran like a dream!

[@juliennacer8871]

what... that doesnt make any sense.....

[@bartsarton2212]

@@juliennacer8871 That totally doesn't make sense. Camshaft timing is set to crankshaft with the dot to dot on the gears. After that you just need to set your distributor timing.

Nice to see someone working on those old heavyweights! I learned about cars and engines helping my dad work on late 50's to mid 60's cars. Seeing that old motor brings back lot of memories.

Looks like that old motor falls into that category..

Hi there. I am A COMPLETE BEGINNER to all things cars. I am a computer technician who loves to troubleshoot and tinker. I have been looking for channels to learn what I can from. I saw your video and came wanting to learn more(I LOVE LEARNING like seriously). I will say that you are right about there being an absolute fuck ton of trolls and assholes on the internet. No one likes them; however, being someone completely new to this sort of thing it is a MASSIVE turnoff to have so much negativity. I usually don't go to the KZbin comments section BECAUSE of all the negativity. So, to have that negativity INSIDE the video COMPLETELY takes away from my potential to enjoy learning from your knowledge. You have so much potential to teach so many people with the knowledge you possess but, the joy of learning is taken out of it completely... Obviously, this is your channel. You control the content you produce. So feel free to keep being so negative. That is your life decision. Just know that your negativity affects people, just like the trolls negativity affects people. I hope you take a step back and re-think things. "An eye for an eye makes the whole world blind" --Ghandi

[@psient]

I just found this series and it is really interesting. I took auto-shop back when it was acceptable and beneficial to do so (way pre 1967) and I did do a rebuild assignment. However, in my teen years I was way disorganized and impatient. Nowadays I can appreciate the focus and attention to detail so I can follow your rationales and explanations of the actual work you do. One thing, although I've been a You Tube fan for years I have never done a video. For one thing I really don't like to hear myself talk too much (probably lack self-confidence) even, when like you, I have something to say. I never realized how critical people are about videos and I am sorry it distracts you from feeling you're addressing only people like me that learn from your efforts. Anyway, I see now that posting also requires a tolerance for rejection. By the way, I like your channel's name as I watch Leonardo Susskind all the time over at stanford. I also like that grad student-girl type who draws on a white board to make videos *can't recall her name/looking glass channel*. Thanks again for all your explanations in this series!

[@jeffbecker7703]

@ 11:20 - What if you checked the pump clearances and found them to be well within spec? Then, the money saved from the budget on not having to purchase an oil pump could be applied to the cost of a new camshaft. Matt, you seem to contradict yourself relative to all your comments about non-thinking AutoZone parts swappers.

[@andrewthompsonuk1]

Fantastic series. This is the best information I have ever seen. To me everything makes total sense. The only thing I question is that cam shaft notch. I would think that unless the journal is cracking up then it should still run OK with modern oil if you smooth out the sharp edges.

[@SchrodingersBox]

Yes I see your point, and thanks for the kind comments. So the thing with the chip in the camshaft is if not repaired, it will eat up the new bearing which will cause the metal particles to cycle through the oil and contaminate all the new bearings rather quickly- I am sure you know this and thus your valid question "why not smooth out the sharp edges of the chipped camshaft"? Well, the reason is we are looking at putting about $1200 in parts and machine work in this engine- do I want to rely on just smoothing out the edges to fix the camshaft? What if the camshaft continues to chip and gouges the bearing and now for just an additional $300 I could have prevented this catastrophic failure? There are always risks and tough decisions with a budget rebuild. Without a budget it's certainly much more expensive but you don't deal with such risks- anything questionable would get replaced. I just felt there was too much risk reinstalling a chipped camshaft.

[@andrewthompsonuk1]

Thanks for your answer I see that given that those cams do not cost too much. Following on from my other question I suppect those old engines do not filter 100% of the oil so it would not take much metal to destroy the new parts.

[@StevenRathburn]

I have a 92 Silverado with a seized engine. I have an extra 350 engine I took out of a truck with a rusted up body that I ended up scrapping. When I removed the engine it ran fine it just smoked a little on startup which I figured was caused by valve seals. I stored the engine behind my shop on a pallet and plugged up all the holes and wrapped it up with a tarp. It sat for about 6 years. Well now I want to throw it in the 92 that I have with the seized engine. I unwrapped it and brought it in the shop and the inside of the engine is not rusted or anything but it took a lot to get it to turn over. It took a lot of penetrating oil and a big breaker bar to get it to cycle and when it did it was rough until I turned it over a few times while pouring oil in the plug holes. Would you think its worth the gamble to throw it in my truck or do you think it needs to be rebuilt? And if so do you think I can get away without having machine work done as long as the crank or cylinder walls are not scored? Like I said it ran fine when I pulled it out. Thanks for any help, love your videos..

[@bigboss9428]

I have read hayens manuals to give me an idea, but I find them a little too confusing and hate reading them. I just took apart stuff, and make sure it goes back the say direction i took it off. I find the manual really good for specifications. However, having a dealer manual is better because it gives you every single detail for the specific car you are working on.

[@Sloppyjalopy123]

Although if the engine is in descent shape. I've re-ringed with new rod bearings with the the block still in. Just hone the cylinders, and have your heads decked. I've had good luck with this, but your right. In most cases, not recommended.

[@ronaldcolman6211]

Those scuffs on the piston skirt aren't a major issue, if you don't want to splurge on new pistons you can just rub them out with a knife sharpening stone. And if you are worried about noise (from piston slap) or friction you can use teflon frying pan repair spray on the skirts after honing them back with the stone. Don't laugh, it's a proven technique in circle track and 2 stroke racing engines.

[@spelunkerd]

I like that trick to prevent scratching the cylinder wall when the piston is tapped out.

[@iananddani]

Thanks for the videos. This made a good reference for me to decide on what I can and cannot do to my engine. 2002 nissan sentra 2.5. Everything looks good. A bit of pitting on the connecting rod bearings. The rings are good but going to hone and new rings. Pistons hardly look worn. Cylinder head exhaust valves are the most messed up. I would really like to do the main bearings but I have no means to take the engine out right now. so They will be for anther day. New bearings. New rings. New gaskets Reground valve seats. Done 109,000 miles on the car.

Years ago we did a budget rebuild on an engine that had suffered due to oil surge on acceleration, it had a front well sump and was in a light car. One evening it developed a knock, took it straight home, crank was unmarked, polished crank, new bearings and baffled the sump. That engine was in that car for years, took horrendous abuse.....

[@SSGTA440]

Pretty good vid lots of good basics here.......one thing, about the camshaft...when you pull the lifters, check the foot of the lifter, if the surface is concave in any way, (lost the crown)...then chances are the cam and lifters will not last long, if you re-use them. The whole job is then a waste of time.

[@stevesharer5758]

Matt. really terrific video series. Had a question you might weigh in on. My neighbor asked me to look at his 96 camry after it overheated(and then sat for a year). I started it up and heard rod knock, unmistakable. So I started taking it apart and noticed the water inlet/outlet cross-over hose had been chewed up by a mouse. Is that why it overheated I thought. Kind of a smoking gun at first. So I put new bearings in and replaced the head gasket.(almost no compression in the rod knock cylinder). After I saw the mouse chewed hose I didn't think about why it overheated until I watched a video of yours about cylinder heads; paraphrasing but "you;ll do it again unless you find out why" was hammered home by you. I wish my neighbor could remember the order of events but he is old and baked. it was low on coolant and driven too hot for loo long and sprung a small head gasket leak by warping the head. It leaked directly into the cylinder that eventually started knocking, (all the other journals / rods were in spec) and that caused the knock. The knock was the only thing that alerted him...or stopped him I should say from continued driving Im trying to piece it together and figured you could guide well. Is rod knock a common result when coolant is introduced into its cylinder, (coolant was leaking right on top of this rod) Also I believe the coolant hose may have been leaking and that the mouse started chewing at the tear while it sat in the driveway and ate all the evidence. Besides driving it while its hot is there something else that shoots out head gaskets, (by way of a warped head)? it has 277,000 miles but pristine cams and no sludge really. btw... I block sanded the head, installed a home made o-ring on the oil pump, re-used all bolts, made all gaskets from rtv sealant, replaced almost nothing and tested everything...I am pinning all of it on the mouse if is grenades

[@SchrodingersBox]

There are two explanations for a knocking noise with coolant leaking into a cylinder. One is that if the volume of coolant is significant enough, the cylinder cannot compress it and the piston "hydrolocks" which will cause a noise similar to what happens in predetonation. This condition will stop when you fix the head gasket, intake gasket, or whatever is the source of the coolant leak into the cylinder. The other reason for a knock is the coolant is diluting the oil causing worn bearings and actually causing "rod knock" which is going to equate to an engine rebuild. Search my channel for "rod knock" for videos related to diagnosis of this condition.

[@pdq914]

apparently half these people didn't listen to the beginning. This is budget "don't buy anything you don't have to, cause you can't afford it" build. reusing all parts possible.

[@2CARGARAGE]

Quick tip: wrap your Mic around the back of your neck and clip it to your collar to avoid noise or clip it upwards out of your front pockets if you have them

[@SchrodingersBox]

Tyler Jones I tried that once before but felt it was a safety concern having it wrapped around my neck while working around the car. Most of the noise is actually from interference with the wireless rather than ruffling. When I have the car between myself and the camera it causes interference and also some electrical equipment I use sometimes causes interference too.

[@snmdws2759]

I've been fortunate enough in most cases to find clearances and specs online. Sometimes though a rental haynes or chiltons comes in handy. I see what you're getting at with the "haynes jockey" comments though. Just because it tells you one way doesn't mean that there aren't other ways to do things. I'm guessing they winced and got butt hurt every time you said it. My only suggestions would be maybe to simulate wiping the tears away from the camera with a shop towel when you say it. Oh, and its also an individual preference but I love plastigage.

[@Giovani25x]

If you need a new engine or need to rebuild one you might as well buy a Jasper motor that comes with a 3 warrenty. They are computer calibrated and the insides are all bran new . The machine shop doesn't always do good work with those engine blocks . I just find some machine shops very questionable

[@aaronjackson2780]

ok, good to kno. i just rebuilt a 350tbi motor to put into a k5 after finding gouges on the bearings from whoever rebuil it the last time. long story short i re used the old oil pump, it looked like new still, but dont feel like metal was ever present in the oil. have yet to start the engine though.

[@gustserve323]

Excellent video sir! Everything was explained really well.

[@wither8]

Great video as usual.. though I'm pretty sure outer (double sealed, looks like?) radial bearing races are harder than neurosurgery. What's at risk is the bearing sleeve surfaces which are actually mating against the bearing (it would have been selected to be rated at a lower Rockwell hardness). Whoever engineered -(Not a mechanic, automotive engineer, not a Haynes manual jockey, but an engineer with a bit of experience in metallurgy) On that journal that's busted, a good shop will have some chemical-vapor-deposit tooling (tradename "Eutalloy"). Basically a heat/spray-gun with a variety of powdered metals (and probably resins/binding polymers) based on your use case. E.g. A nice piece of 30' 6" Aqualoy eight month old marine-shafting is perfect except for some guy who whaled on a nut, stripped the shaft threads. Instead of replacing the nearly-mint part, my machinist built up a solid spray chucked the shaft in the lathe to cut new threads and bang-bang. Three hours of labor. Downtime was less than a day

[@prezillogic9230]

excellent and practical not like reading manuals all day then are not able to even undo one bolt well done

[@bchrisl1491]

Does the exhaust system have enough negative pressure that would allow oxygen to flow into the system? I always thought an exhaust leak would allow exhaust to escape into the atmosphere rather than the other way around. I always enjoyed the transmission section of the Haynes manual, but the pages never had grease smudges on them like some of the other chapters.

[@SchrodingersBox]

Yeah an exhaust system definitely has positive pressure as easily confirmed by a exhaust backpressure gauge. tests I have done to look for the fabled O2 sensor lean condition from an exhaust leak indicate you need a doozy of a leak to get a decent amount of Atmospheric O2 in the system.

[@scramblendan]

So the fingernail test... is it that you can feel a grain across the bearing surface or is it a distinct groove or ridge worn into the bearing? I suspect that the my cam bearings are worn badly in my engine. Is there a given clearance between the cam and it's bearings that would distinguish excessive wear??? I have a misfire which my mechanic could not find the cause after running several tests. He suggested it could be a worn out exhaust lob on the cam for cylinders 2 and 4 on the cam but I have a roller cam and I see little to no wear what so ever through the holes in the top of the block so I'm wondering badly worn cam bearings?...but, I also don't have the cam out of the block yet so we'll see...

a little less belittling your audience would be cool. awesome videos otherwise. keep it up man!

Awesome vids broski! Very Informative. Interesting and very simple tips for keeping track of push rods, lifters, p rods etc. Never thought of that simple deal. KEEP up the vids! 98% hands 2% theory!

[@davidreed3188]

Hello Matt. my name is David, I am in much need of these videos and would like to say thank you. I have a question or two if you could answer that would help me a tremendously. well to start I recently acquired a 1986 nissan 300zx non turbo. it has in incredible amount of miles and I want to do a complete rebuild. also I want to do it myself because I'm hard headed and want to learn how anyway. could you tell me what tools I will need and any extra tips would be awesome.. to note I'm car dumb most I've done is oil changes and spark plugs. but really want to make cars a hobby and this could be a great chance for me. thank you.

[@SchrodingersBox]

david reed My advice, David- do what I did. Practice on an engine that will not be your daily driver. I started by buying a junk car for just $200. Take it apart and rebuild the engine (using a rebuild video like mine or a service manual or whatever) just using the same parts- even the gaskets. This will familiarize yourself with the procedure, tools needed, etc. But the main thing I see from people wanting to get into this hobby is they just never got off their ass and do it. They watch, read, study, post in forums, etc but they never actually get started and ever turn a wrench. So get a junk engine, and just do it for god's sake. It's exactly 100% how I started about 8 years ago and I haven't stopped since.

[@pinkhead6857890]

Only 2 out of 8 of the pistons on my 318 have scratching on the sides. Can I get away with replacing just those two or do I have to get a complete set?

[@TheFirstgoldking]

Howdy..has that engine been rebuilt with a bore and oversized pistons before..I ask because you didnt use much effort to tap the piston out if it had a std bore with 50yrs of ridge.. if the piece of cam that broke off the bearing journal hadnt shaved the cam bring during all the miles its gone since it broke .wouldnt just a little deburing of the sharp edge allow it to go another decade or so..the journal being a bit narrower for such a small area wouldnt matter and save another $100 on the build.. good video sir .. my Chilton manuels start at 1953 to date..

[@SchrodingersBox]

VN Dustoff No the bore and piston specs indicate stock, it will be evident in Part 4.

[@adamm1284]

I've replaced bearings in a knocking engine by dropping the oil pan. I'd say I've done it for customers maybe half a dozen times, never had any problems with bearings turning over. I guess I'm just used to working with very little.

[@SchrodingersBox]

No way I would do that, especially for a customer. And if there was engine knocking how did you repair the journal??

[@adamm1284]

Schrodingers Box scotchbright because it makes me feel better. The journals aren't trashed to began with and with the cost of bearings and labor to be around $200 for a repair that will get you by. Early career small town mechanic bs. People didnt have the cash, I just use plastigauge and if it's even close I'll run it. Catching it early is always best. I've found small blocks, toyotas, and hondas are almost impossible to kill. I've gone as far as just replacing one piston from a junk motor and "match" it to the accepting cylinder using a hone and a drill. That guy got away with robbery because he is still driving it today. Making shit work is probably my favorite part about being a mechanic. Funny name btw, I'm not sure a lot of people get that, I didn't notice it until the little cat face was on my screen lol

[@SchrodingersBox]

Yeah i even had a truck that I used different pistons from different trucks in different salvage yards- but that is a lot different that bearings on a journal with even a little rod knock damage. Not to mention the lowered oil pressure. But if that’s all you had to work with it’s better than nothing.

[@adamm1284]

Schrodingers Box most of the time it was people not replacing their timing chains and the plastic guides break then the oil pump picks up the plastic and clogs the pickup making the motor knock then suddenly it's making enough noise to bring it the shop.

[@trevorbyron8181]

Like your videos as of my most watched next to Eric the car guy and humble mechanic. I like it when you rip those off who rip you off...just don't take their b.s. serious, cause your expertise is amazing..

[@Schetmesa]

Very good video, excellent ideas and info, thank you for your time

[@paulmannering3831]

Best explanations ever and so clear to learn

[@SchrodingersBox]

Glad you think so!

[@FirstLast-my6ke]

Question on timing chain deflection measurement: is it not important to put tension on one side and measure the slack side? Couldn't tell if you did or not. Thanks.

[@SchrodingersBox]

Yes thats how you do it.

[@jonyoung6405]

I'm thinking of rebuilding a GM 4.3 V6. Thanks for the information.

[@SchrodingersBox]

You should! Good luck with it!!

[@jonyoung6405]

I blew an oil line that went to my fender mounted oil filter and didn't catch it for a few miles. After oil line repair and oil refill , my engine valve train sounds a little louder. I might send an oil sample out for analysis just to hear more bad news . Thanks again. And new sub.

[@hdjjfhdjif878]

Why not do a video on why you don't like Haynes instead of getting mad at viewers? Most of us are not professionals and would have no chance without a manual. I don't know why that is a bad thing, seems better than just winging it. Searched through your content and nothing came up for Haynes.

[@SchrodingersBox]

I am not a professional and besides you missed the point.

[@hdjjfhdjif878]

@@SchrodingersBox could you maybe explain the point you are trying to make? You know most people who need to follow the manual dont have much experiance, why the hate? I just dont understand why you would be so focused on putting people down who are obviously as interested in it as you. It's not like using a manual immediately makes you into a dingus. I get the point that you should be understanding the purpose of what you are doing and not just pulling stuff off, but the manual doesnt prevent you from understanding what you are doing. The people that just pull stuff off willy nilly would be doing that with or without the manual. The people that understand what they are doing do it that way with or without the manual. And why the passive aggressive response? Maybe it wasn't supposed to be that way, but it was so low effort that's how it came off. Literally just asking a question.

[@SchrodingersBox]

@@hdjjfhdjif878 The point is, the internet is filled with thousands - nay, millions of people who give advice on automotive but never turned a wrench- they just use the flow charts from service manuals and spit out advice that they have no knowledge of first hand. MOST people on the internet do nothing more than blow hot air and it feeds the whole parts-changing mentality. The aggression is against the "armchair mechanics" dishing out advice on the internet- not against the manuals themselves or people who actually use them in practical application. Go to any forum or look at most videos on fixing a check engine light. The idiocy is absolutely epidemic.

[@hdjjfhdjif878]

Agreed, I guess I just misunderstood in the context of the video. We all get annoyed at those people too, especially when on the receiving end of that advice as many of us have been. Thanks for clarifying and thank you for the video series, should be of use as I rebuild my dirt bike motor for the first time

[@SchrodingersBox]

Glad we got that cleared up. Even professional mechanics are guilty of it. I have many videos where a professional mechanic misdiagnosed everything from EGR to AIR to secondary ignition faults that I was properly able to diagnose as a DIY (see video Diagnose a misfire like a boss DIY vs Pro mechanic). These are the people that weaken the resource KZbin could be.

[@iliketobuildstuff7013]

for the cam shaft, do you think you could get away with welding the chipped area on the journal and machining it back down? or would it be a bad idea under the circumstances of the cam shaft (excuse my spelling if it is incorrect i have little experience)

[@SchrodingersBox]

Pretty much if that chip is in the path of the lifter, you have to replace the camshaft.

[@iliketobuildstuff7013]

thanks for the quick response.

[@wooters12]

Did you mean rod and not piston replacement when measuring rod side clearance?

[@davesmith7159]

What brand of engine is the easiest to rebuild? I am curious because I am considering rebuilding 1 of the three vehicles I own, a 2000 mercury cougar, a 2001 civic, and a 1999 tahoe. All three vehicles have completely shot engines that have issues and would require a rebuild or replacement to continue driving. I want to start a rebuilding project, but unfortunately my wife only allows me to keep and rebuild one of the cars and get rid of the other 2. What car would be the easiest engine to rebuild they all are reletive in age?? Thanks,

[@SchrodingersBox]

Any engine is easy. Once you get the engine torn down they really are almost all identical

[@MacClay8]

I tried to watch this scientifically, but I was unable to watch you take apart an oil pump all day. I only managed to watch that section 6 times before I started looking for used engines and Hayne's manuals on Craigslist.

[@gregrobinson9827]

i love this video learn alot from it! and iam not a big fan of Haynes shop manuals myself or chiltons for that matter have found some false imformation there back in my younger days I am more of a hands on kind! great video look forward to seeing more!

[@chadmilliser1]

haha now everyone will be asking for the the 2 liter trays from the stores that they dont give away - Great job - Good videos-

[@Rap5005]

thought your comments on dumb asses who think they know it all were funny man ! Keep up the good videos :D You've been helping me alot through my journey of learning !

[@blocksopiff]

Well, I've been leaning towards an engine rebuild on my wife's van because of some issues I've had. I think this video and part 1 pretty much confirm I was right.

[@hasbeengood]

I have a question for you: on an engine that has no knock, good compression, no oil consumption, that goes well in other words, but the only thing it has is 100 000 miles on it. Could you just swap rod and crank bearings and piston rings to keep it going well for another 100 000 miles without rebuild? Considering I would like to put in a better cam (new cam bearings) and redo the valve train (lifters and roller rockers). Of course the oil pump was in the cars for a new one. I know you'll tell me if it ain't broke don't fix it, but i figure it would be more complex and expensive if I waited for it to break down. Engine runs well, just want to wake it up some. Engine is a 350 LT1 from 1995. Your thoughts....

[@SchrodingersBox]

Not possible, no. You need to do engine removal and dismantle entirely to repair from worn bearings. At best the contamination would make the hack repair short lived.

[@hasbeengood]

Even if journals are not scored and nice?

[@SchrodingersBox]

hasbeengood Sorry- misread your first part- that there is no knock. If there is no knock and good oil pressure I have no idea why you would want to replace the bearings but if you did, you may be able to drop the pan and insert rod bearrings but the mains requires removal of the engine since the crank must be removed. I really don't recommend you do whatever you think you want to do though.

[@hasbeengood]

My goal was to refresh the engine rotating ass'y so I could hot rod it a little and give it a chance to cope with the extra "ooompf" of the go fast goodies. So with 100K miles and fine working base end, you would have no problem with putting a hotter cam, roller rockers, valve springs, headers and ECU tune affecting reliability. Provided the car is driven in a grown up way?

[@hasbeengood]

thought of also installing a new timing chain...

[@ernstjames4890]

You are by far the best. Thanks
