Just bought an '07 GMC Sierra 3500 (dually) (LBZ) which I knew needed HG's (relatively low, 160K mi.). I'm 76 years young, and have been wrenching my own stuff, all my life. I had a '68 Nova (H/SS) that won Super Stock Eliminator at every monthly race for 2 years straight !! After watching this video, I decided to do the job myself. My son-in-law (63 yo) said he'd help. Ya' gotta remember... "It's a engine, we are the HUMANS !! We are supposed to be smarter than the engine" !! Thanks for doing the video.

I am a cummins guy, but enjoy your videos on the duramax trucks. I like the fact that they protect the front end and paint. That is a good mechanic who takes pride in what he does. if i was to ever buy a duramax i would make the long drive from upstate NY just for them to work on it.

[@CumbersomeDinosaur]

I did this by myself in my garage back in 2013 on my LLY. I would rate this job as “intermediate”. It shouldn’t be too bad for someone who has some experience working on cars but I wouldn’t recommend for a novice or beginner. This video is fantastic. Only thing I would add: -have plenty of spare fuel and coolant line and replace all of those small rubber hoses. Mine were dry rotted. -I would get new glow plugs. Several of mine broke off in the head and the machine shop had to remove them. -get new fuel return lines. A few of mine broke off in the injector. -use care with all of the harnesses, they break easy -take the time to clean everything before you reassemble, esp if you don’t have deletes -at the end, I filled the coolant with water, and idled for about an hour to check for leaks. Then changed the coolant and oil.

[@logan8256]

I’m 18 and have no mechanical experience. It came down to I could only afford to do them myself. I studied this video for a week, got certain tools for the job and tackled it all by myself. It’s all about will power and determination

[@cdsmit27]

​@logan8256 I've watched this atleast half a dozen times. My only problem with it is they never show how to clean the metal dust out of the cylinders and coolant ports before reassembly. How did you do that and is your truck still going strong after the job?

[@CumbersomeDinosaur]

@@cdsmit27 There's different schools of thought on this. My way: First, use compressed air if you have it to blow everything out. Rotate the crank so a few pistons are at the bottom, take some sort of grease, coat the cylinder walls, then rotate the cylinders passed TDC. You'll notice the piston rings will catch all the crud and bring it to the top for you to wipe out. Repeat for remaining cylinders. Anything you missed will get caught in the oil filter, and that's why you change the oil after your first run up. As for the water jackets, hopefully you stuffed a few shop rags or put tape over them to prevent anything from going down there in the first place. If you feel some shavings went down, it really shouldn't be a big deal and just flush the cooling system after you're finished. P.S. I sold the truck in 2019, but it ran smooth and flawless. No issues several years and thousands of miles later.

[@fbh31118]

I have a duramax that someone tried to do a share head gasket job and lost the dowel on the driver side. It will allow the head to slide downhill a few thousands so when reassembled it will starve the oil passageway and lock up the push rod between the gasket and the head casting. Also had a crap @$$ shop try and repair it and use the same handed gasket on both sides. Grrrrrr! Love the quality work being done in this video!

[@coreytcondit]

Good video. Only things I thought you left out is what to replace while you're there. Rebuild turbo, new water pump, new oil cooler gaskets, go through wire harness and replace protective sheath. I also replaced my reservoir tank. While the heads were out for machining I had all the intake and valve covers powder coated semi gloss black. Added mishimoto up and down pipes, PPE exhaust manifolds and a dual fueler. Hard to believe some guys skip the valve lash. You don't belong wrenching on a duramax engine if you cant do valve lash. My early 06 LBZ had the rivet head gaskets and just started to show signs so I did HG's and studs preventively. Cheers.

Looks like you guys have it down to a science. How much does replacing the head gaskets cost? Great job by the way..........

[@dawgfather2101]

You have know idea! I have an 04 duramax that only has 194k miles on it. I had to replace injectors, so I got my cousin (who is GM certified mechanic and works mostly on Duramax) to help me. Well, this video brings back the nightmares!! I've always thought of myself as a descent (spare time) mechanic.....long story short, I will never do that again! To me, nothing on a vehicle should be that ridiculous to get to. I saved alot of $$ but I believe it might be better just to pay someone to do it. I'm sticking to the easier stuff, Brakes, alternator, water pump etc etc

[@FLYWHEELPRIME]

Most places will charge between $2k and $4k just for labor. The parts kits are between $600 and $1200 cost depending on if you get ARP studs and upgraded gaskets. I totally charge $3k total if I'm doing it on the side for guys from a performance forum, but that's only if I don't have a bunch of work lined up.

[@noahthompson9930]

for anyone doing this job, I'd recommend using the 3M bristle brush for cleaning the block. it doesnt make a mess, it's great for getting the soot off the block from where the blow was and it makes the job much faster. also blow out the stud holes with air and shop vac everything out, otherwise you'll be pulling the heads off again go blow them out. Do yourself a favor and just leave the exhaust manifold on. The 3 bolts connected to the manifold, one is in a very tight spot that is impossible to get a socket on. I bent wrenches trying to get it off, so just leave the manifold on. Also it wasnt discussed in the video but I changed my oil before I started it up. given that the oil was contaminated with coolant I didnt wanna risk any further damage to my engine.

[@dougsavery5442]

Yea personallyvi would have stuffed rags and shit in the cylinders and the pushrod holes. Great idea to be dropping sand paper particals into holes where the fucking cam is. Cylinders easy to clean out but better hope nothing dropped down those pushrod holes lol

Awesome video. Its was extremely helpful for me doing my valves after putting head studs in. The only thing I would recommend is to actually loosen each rocker before torqueing down the main assembly. If they were tight like several of his were while being torqued, then you loosen them to get the feeler gauge in, you wouldn't have 30 ft lbs. anymore.

My truck will always have that story built in there for extra horse-torque-power when i need it also, so I'm stoked, and I'll be thanking you guys! Thank you all. Could not have done it without you guys at that time. Thank you for your generous spirits and super skilled and steady ways. Thank you for sharing. God Bless!

I started out trying to remove my heads by leaving the cab on. Like in the video. The up pipe bolts I was basically having extreme problems getting the bolts broken loose. Not twisting them off. I changed my plan, and took the cab off. It was very much worth the effort to do that. Then everything became so easy to work on. Don't know if I would even try this job regardless of truck condition without doing a cab removal. Just my .02

[@P1ayD0hpaul]

That’s one hell of a way to make 8 bolts easier to remove. Pulling a cab is no easy task. I’d much rather pull the engine than remove the cab. Obviously you have some sort of gantry crane at your disposal, and I’ve pulled a cab and box so I know what’s involved. I’m sure the bolts are a PITA, but shoot some PB, wait a day or 2, and use some heat if you have to. Way easier than a cab pull.

Head gaskets 101. Fill all openings and cylinders with shaving cream. Scrape with gasket scraper. Get the largest knife honing stone you can find. Bass pro had an 8” x 3”. Start with course side using wd40 going lengthwise. Finish with fine side. Don’t go crazy. Vacuum up and turn motor over wiping cylinders. Oil cylinders and turn over. NO SANDPAPER EVER!!!

[@cdsmit27]

Sincere question. What do you mean turn motor over? It's not able to run at that point.

[@elzeeky1]

I did that to my Lb7 back in 2017 its very time consuming never worked on diesel before just gas engines, it all started with filling up at diesel station that contained free water in their underground tank. It busted three injectors plus one of the seals on the high pressure pump which led to diesel leaking into the oil system. I had to tear it all the way down due to Lb7 injectors are inside the valve cover. Once there I had the cylinder heads rebuilt. All brand new MA injectors, new water pump from MA , also a fuel air separation system from air dog and got rid of that OEM useless water catcher and filter. he he. still going strong 165k miles on it. I wish this video would've been out then it would've taken me a lot less time to complete the job. Instead of a month and a half I probable would have done it in a week.

[@maxhauler]

Great video with lots of good info and care being taken, except for one thing that really bothers me: When cleaning the block surfaces prior to mounting the heads, the use of sandpaper as shown here will result in a large amount of industrial-strength abrasive sand and iron particles collecting around the top edge of all pistons, sitting on the rings as well as dropping into the oil passages and even water passages. I am sure this will cause a lot of damage. There has got to be a better way. There are no easy solutions to this issue, but I would love to hear some suggestions. (Solvent, wiping, vacuuming, air blasts, oil filter/change .. none of those steps will removal all the abrasives. For sure a bunch is going to wear the cylinders and depending on how the oil passages route .. maybe crank, cam bearings lifters and more.)

[@packfannumber1]

Most people who take the time to sand the head before reinstalling will take an air gun and blow out all the cylinders and everything. They might not have showed it here but im sure that's what they did. These guys seem way too good at their jobs to let something like that slip.

@@packfannumber1 that's not even close to what maxhauler was pointing out. You can't "blow" this type of debris out of an engine without blowing more of it down deeper into critical areas that WILL cause abnormal wear and tear on the customers engine. This is just irresponsible work procedures on their part for using this sloppy, incompetent process for cleaning the deck surface. 4 oil drain back holes in the very bottom of the deck that go straight into the crank case(oil pan). How are you going to "blow" that out without sending it to the pan? Not to mention the 80 grit debris that fell into the pan because they didn't block the passages before they "blow" it deeper.

They did an awesome job on that headgasket job.

Correct me if i just didnt see it and he actually did. Other than that they did a good job and you made a very detailed video. Too bad it came 4 months late because i would have used it to my advantage.

[@jeffscott3160]

Yeah I personally would have done a little more to seal off other parts of the engine from sanding grit. That said though, even if some grit made it to the oil pan and was picked up by the pump, the first stop it hits is the oil filter before moving on to the bearings and other critical wear surfaces,

[@tedgerstenslager2949]

This is a helpful video for sure. BUT if your thinking about doing this job yourself watch this video in it's entirety.

(Anyone can rip something apart) Example put your injectors in before your top fuel lines 55.55 in the video. On the drivers side after injectors are in install HP fuel lines from main fuel rail to injectors START WITH # 7 #5 then main fuel line next #3 #1 if not you will be taking off everything they told you to put on to tighten the fuel lines from #7-#1.

Awesome production quality! Every time I see a teardown I remember why I hate how overly complex they made this truck haha. But a great vid

[@2ndAmendmentGlock]

I have an LMM, the turbo on mine is too close to remove the bolts at 24:00 you have to either remove the turbo or get the last bolt completely off when the heads are loose. Also the oil dip stick tube runs up through the passenger side, in between the engine mounts 😒 down behind the starter motor and into the bottom of the engine. To save yourself tons of work and frustration the best thing to do is to take the exhaust manifold off the heads instead of trying to remove that oil dipstick tube. Also to make the job 100x easier just use an engine hoist and some straps to carefully and slowly remove your cylinder heads...

[@Surge_Stream]

Won’t metal shavings go into the motor and cylinder when sanding?

[@P1ayD0hpaul]

Shavings are visible pieces of metal. Sanding doesn’t produce shavings. Anything in the cylinder will blow out with a quick blast of air. It’s possible tiny debris could fall in the coolant passages, so somewhat valid point. Yet either a stone or sandpaper has been used for decades, so it’s obviously not an issue. These guys haven’t invented any of the work being done.

[@matthewtabolt4145]

This is great, showing your own shortcuts/helper points the way i use too.

[@Gregg0112]

If your intentions are to drain the system then do that before you pull a cap off a pressurized res. Ounce you no longer have pressure pushing coolant out the drain then pull that cap so it will flow

[@mj-7444]

Ok your other video did suck but seeing this one tells me how good you can be. Much respect Subscribed

[@Iatolaazzahola]

Nice video of going through the process. A couple things you didn't address for your customers. The GM Technical Service Bulletin on these engines specifically goes over this part of deck prep to keep abrasives OUT of the critical areas of the engine. You are sanding the block deck with 80 grit sand paper allowing the sanding media to fall into the engine at the lifter openings and the 4 oil drain back holes in the bottom section of the deck, then proceed to NOT explain to people how important it is to NOT get sanding grit down into the oil system. How do you get away with that? Then you fail to explain that the main issue that you would be attempting to correct with a sanding block on the deck is that the deck will have a low spot at the exact point of head gasket failure. Look @35:46 in the video where you happen to shine the light on the entire passenger side deck, you can still see the low spot(dark area) in the deck that coincides with where the fire ring on that gasket was blown at the rear of the cylinder. This is where the fire ring seals on the deck, the deck is still low there. I'm not saying it is going to fail, but it has potential to blow again in the same spot "if it is too low and not addressed properly". I know you do a lot of these jobs, how many have failed since you did this to them? You may have taken steps to ensure this didn't happen, but I don't see you addressing it here in this video, please inform your customers about these not so minor details I've brought up here. Thanks for showing your process. For people watching, DO NOT SAND your block deck like these people do in this video UNLESS you can keep these heavy abrasives out of your ring lands, and your oil and water passages!!

[@TheSchyllerwade]

I do wish someone would respond to this…or at least share what they believe is the proper method.

[@cdsmit27]

Bringing this up is a waste of time. I've made a couple calls to the shop to speak with one of their techs to get some answers about this specific issue but their techs don't speak over the phone. So with no explanation of how they clean the block, this video should NOT be used as a reference. A lot of people's motors will end up in an early grave if they follow this video.

[@Iatolaazzahola]

Yeah, you're right. They've been asked this question repeatedly since I posted this reply, crickets is all we're hearing. Out of 435k views, 4600 hit the like button. GM put out a technical service bulletin on the correct way to clean the deck after checking it with a straightedge, they say no less than 600 grit sandpaper is to be used. @@cdsmit27

[@nate5102]

Very serious question and I hope it gets answered . When the tech was prepping the block surface with his sanding technique, doesn’t that cause all that abrasive material and small metal particles to get into the oil passages into oil pump and all that ? How do you go about cleaning that up ? Won’t that destroy bearings over time ?Please reply

[@notimportant4994]

Yea you got a point

[@danthatguy9686]

[@nate5102]

@@danthatguy9686 I’ll give you the info . That grit is going into the crank case and stickin to the casting . Then when you drain the oil after finishing the heads (like you should do ) all that grit makes atleast one round around the bearing before the filter catches it

[@burtonkidd]

Hey Josh, Have you ever seen a blown head gasket on an LLY that doesn't lose coolant but has a hard upper rad hose and occasionally pukes coolant out the over flow tank if run hard? Coolant tank isn't black either

[@TruckMaster]

Yes it’s still possible you have a failed gasket but pressurize your coolant bottle and check for leaks first but it can also be your thermostats or radiator.

[@bernhard8540]

i use the line wrenches for all sorts of stuff they are so nice if your trying to not round stuff off haha but they work great for brake-lines and fuel-lines etc like you did in the video they are just a great invention rather than the regular open end wrench that usually spreads open and slips and rounds stuff off haha been there to many times lol haha great video as usual

[@shannonabernathy2656]

Love the video! Very informative. The only part that makes me cringe is sanding the block like that without trying to keep grit out of the block. I see several other people voicing the same concern but no answer as to why this is ok. Are we worrying to much? Now I'm not a pro mechanic or anything but i have turned wrenches most of my life privately and a little in a shop (also former Army 63W) and this just seems like a terrible idea?...

[@321CatboxWA]

How would you keep the grit out? I would stuff the lifter galleys with lightly oiled big fat car wash sponges cut to fit .

[@jaydunbar7538]

@@truckinman86 the old 2 strokes make some fantastic sound but thats the only thing they are good for. Poor fuel economy, high maintenance cost, and crap torque compared to anything made in the last 20 years. yes you can modify them to make them better, but if that same effort and cash is put into a newer motor the 60 series will dominate it in all ways.

[@canadagoose27]

I have an 2005 GMC LLY (95,000 miles) and also a 2002 Ford 7.3. My vote for the best diesel is the 7.3...much simpler and no head gasket problems ever over the 290,000 miles that it has on it now. The LLY is definitely more powerful and quicker, but i would rather trade some power for longevity and reliability. Thanks for another great video. Used your turbo removal video and removed mine to free up the Unison ring. Now back together and running great!

[@chakagillis]

Cummins is the best diesel, unfortunately dodge/ram is the worst truck. Ford is the best truck, but powerstroke is the worst diesel. The GM Duramax is a nice compromise

You need an old valve adjusting tool like I got from my dad for setting the valves on a 235 6. Socket mounts on the handle and a knob on top turns the flat blade to adjust the valve. Hold the knob, turn the handle to tighten the stop nut, done. Wrench and screwdriver is slooooww.

[@saltysteel3996]

So what's different between the LLY and LBZ when it comes to the heads and block? Because the LLY engines are known for overheating and blowing out head gaskets. The LBZ doesn't seem to have that issue. Edit: Just curious is all. I have a LBZ truck. It's in the shop having the trans built and beefed up. Getting ready to add a 5 way tune setup soon. Do I need to worry about blowing a head gasket or having the heads studded? My max tune won't go over 150HP and the max tune won't be used that much either. This is my daily driver truck. Mostly stock. So far the exhaust is straight piped. No lift pump and no EGR delete. Planning to do both of those mods soon as well.

[@billbrass1248]

Salty Steel a lot of people blame the lly turbo mouthpiece for over heating issues..and yes it is a restrictive piece and will help the truck breathe much better reducing heat from the turbo, but ultimately iirc the design flaw was in the gaskets themselves with these trucks, some are just prone to shooting shit..
