Thanks for this. I am an old gasser. Have never owned a diesel and bought a Chev 3500 6.6 Its rather intimidating when looking in the engine compartment, this video puts me at ease , thanks again.
Your videos went from a muck around, to a very good format overnight! I see the extra effort thats gone in, and I know how much longer this format takes to film and edit. Just wanted to let you know it hasn't gone unnoticed - thank you!
Idk who the hell would thumbs down this video. Thank you for making this video. Makes me dread having to rebuild my LLY. I’ll prob watch this a few more times.
I absolutely do not like anything chevy related, however I enjoyed this video. You did a very good job. Almost like a professional tutorial. Very good job young sir.
I want to commend you on your video. Very informative and extremely nice to see a video without foul language that the kids can sit watch as well when they are wanting to learn about mechanics. A+++++++
Very awesome video my dude, your descriptive and articulate approach is refreshing. Kudos, as an LB7 owner about to do a tear down I can't thank you enough for the info you have shared! Truly a blessing, cheers with 6 beers! :-D
44 people said no ? Why ? Great information thank you amigo . I have an lly and had to do all these deletes and the wherly custom y bridge and set up and a few other minor repairs and new injectors. I started doing it with engine in truck but I have a severe OCD. And took the engine out to clean and better see what I needed to do and this video helped alot thanks again
pretty creative intake on that motor. It's nuts how little room there is under the hood of newer vehicles to spread the motor out. I think some of the compact packaging is for quick install on the assembly line also. thanks for the video Wyatt I enjoyed this a lot.
Dang ...nice job on editing this video...and Damn I can believe that tiny broken pin leads to no oil pressure and a toasted engine...great video and looking forward to the rebuild
Fantastic video, really helped us get to the crank shaft sensor ring (forgot what it's called) the three little Allen head bolts all fell out and wouldn't run. That's for the detail. Bill
Was very helpful. Im currently doing head gaskets on my LLY and wanted to see a tear down done b4 i started. Not the same but similar. I have now almost finished putting everything back togther and has been a learning process as this is my first diesel project. Like i said very helpful thanks.
As a fellow mechanic, I can appreciate just how ugly those motors really are, like you can barely see the heads... Great video man was a pleasure to watch.
Love the video bro. I used to do he's machinery so love me a diesel. But I love a Detroit. Nice sign 9 1/2 that's sick. Love the diesel content, keep up the great work bro
Very informative video. Can't wait to see more Duramax content. The pin that was broken. Is there a pin upgrade for the engine or do you have to go with the factory pin.
Great video however I would like one on putting an LLY together starting at the long block point. I know some will say to reverse the video or process but it would be nice to have something showing each part ASSEMBLED one at a time. Nice clean video with no extra drama and straight to the point. Good job
Whenever I work on Isuzu engines I use a roll of masking tape and number the lines as I remove them to they go back in order. Just my tip on line install/removal
Great video man this is my first time checking out your channel and i subscribed. My question is because of the better head design on the newer engines is it possible to swap over newer heads and other supporting parts to an older engine? Thanks in advance and keep up the videos 👍
Well done video and excellent mechanical skills! I just did injectors on my '03 CA LB7 (with EGR) and I'm almost sorry I didn't pull the engine. Just kidding, of course. I notice your upper valve covers came right off since they can be a bear. I used a large block of wood and a heavy hammer to pop each end loose. Interesting to see all the bits beyond what I had to remove. Great job!
I had new injectors replaced and ARP studs installed on my LB7 back in April '18 and last week the crank shaft snapped. Sold the truck with blown up motor for 4k after having dumped 8k into it 😓
Where abouts in Cali do you reside, I'm here in the Modesto Stockton areas about one hour from the east bay area? The reason I ask is because I'm getting ready to tear into my LB7 real soon as my engine may have lost that pin as well. Thanks for the reply. Have a good week ahead...
these two wires need undone too,,, Haha... that's some funny shit... but this really is a great video and the very best i have found on the internet this guy really is one of the best ...
That's a lot to remember. It must be annoying to have a wreck motor because of a tiny cheap pin broke. Also even if you notice the oil pressure has gone I guess it would still cost a lot in labour (sorry English spelling) just to fix the dam pin. Good video bro, you have a good mix of content
I have a 2003 lb7 and it just randomly lost oil pressure, it only has 135,xxx miles on it, it's a learning process for me and working on diesels, I did the injectors myself, but how common does the oil pumps fail on these or would it be something else, and this video helped me alot cause I can't find another video where they are removing the oil pump or even talked about any of that,
Check your oil pressure with a mechanical gauge or use the squirt method. ( loosen up the oil pressure sensor while cranking and pull your fuel relay to prevent it from starting)
These remind me of another pain in the ass that was the Perkins TV8.540M, a marinized tractor twin turbo diesel. The cooling system was a haphazard design, and required frequent service or else you had to buy expensive aluminum housings. Just changing the raw water impeller and removing the sea grass from the tube bundle heat exchangers were excruciating projects. Assembly, like this one was critically sequential, or else..
Question! will try to be short. had an Lb7 with 400k on it. I did injectors on it twice, second time was rushed and didn't go so well as you'll see. Fired right up and sounded beautiful. In park, sustained 3000+ RPM for a few minutes no problem. no smoke no oil leaks at valve cover, balance rates at idle are 0, +/- .1, great. 2 miles down the road, at about 50 mph, loud knocking noise on passenger side bank and a copious amount of white smoke out of tail pipe, does NOT occur upon restarting engine. Until I reach 50pmh, like clockwork it happens again. but that's not my concern. After a few rounds of this I got rather frustrated and to my everlasting regret, stomped on the throttle after the knocking noise occurred and the engine understandably went dead. re ignition yields the sound of a healthy starter spinning and a very loud thumping noise on passenger side. Engine never fires. depending on what I might have done.. I'll pull the engine and tear it down and try to get it running again. Any thoughts on what I did when I stomped on it?
Did you ever find out what happened to your engine when you stomped on it? I had the same exact t thing happen to me a week and a half ago. Very dissappointing...
Great disassembly video. Does the pin that locks the crank gears to the oil pump drive gear have a fix or upgrade so the engine rebuild does not have this flaw built back into it again? Sad that the pin is likely too small in diameter or not the right metal alloy to handle the job. I'm no expert but those oil pumps in gasoline engines seem to have a better design to them. How many miles did that engine get before the pin broke? Some of us viewers need to know what years were LB7, LMM etc. Many don't know the code but do know the year.
That keyway that broke off - isn't that just for alignment purposes and the clamping pressure of the crank bolt keeps it all in place? I've seen similar things happen on timing belt vehicles when the crank bolt wasn't torqued enough. I'm inclined to think the bolt wasn't tight enough and then the slop on the keyway caused it to break off. Great video! Keep up the good work!
Quinton Cheatham technically not a keyway, it's a dowel pin. Further keying the crank actually prevents this. And will allow it to hold alot of power, along with an alternate firing cam to relieve the stress off the front of the crank, due to the 1-2-7-8-4-5-6-3 firing order. It's the fire at the end of the order, (3) followed up by (1)-(2) that breaks cranks, almost always at the front. But usually only when adding significant power.
Great Video I have an 03 LB7 with 275,000 miles, I'mon the 2nd set of injectors. Engine has a lot of blow by so im sure over the years I have washed the cylinders down and probably ruined the rings. I really want to put LLY heads on it when i pull it for a refresh. DO you have any info on this swap. I found a guy on the internet that will take your harness for an LB7 and convert it to an LLY to fit the LB7 truck. Please comment
Great video! You really do a nice job explaining. That's a nice engine stand. Is that homemade or did you buy that? If you bought it, where did you get it? Looking forward to more diesel content!
Second questions I need to know We were asked by our mechanical repairer for buy a long block Sent here to Australia which we did as we thought . My son in law here is a mechanic and said to me we got a short block and not a long block which in all honesty I don't know the difference Can you please explain to me what we would expect on a short block and a long block ...not a turn key engine Thanks for any help given Cheers Mick

As a mechanic myself I respect your methodical approach to stripping an engine. Very enjoyable to watch.
exactly well said
“A 5-6 beer project…” 😂
Classic! 👍🏽
Respect from Australia for advising how many beverages are required at a minimum.
GonePro27 as another Australian I fully endorse this message
I hope one day when I can visit Australia It is just like I read about! 😀
Thanks for this. I am an old gasser. Have never owned a diesel and bought a Chev 3500 6.6 Its rather intimidating when looking in the engine compartment, this video puts me at ease , thanks again.
probably the best video of tearing down this motor I've found on here
I watched the whole thing and don't even own a diesel. Well done man! always enjoy watching a tear down
Your videos went from a muck around, to a very good format overnight! I see the extra effort thats gone in, and I know how much longer this format takes to film and edit. Just wanted to let you know it hasn't gone unnoticed - thank you!
Fuck yeah 32:26 minute video! The assembly/disassembly videos are awesome. Keep up the good work Wyatt.
I'm not even really a diesel fan but I'm intrigued by mechanics and how things work. I ended up watching the whole video, well done sir.
Idk who the hell would thumbs down this video. Thank you for making this video. Makes me dread having to rebuild my LLY. I’ll prob watch this a few more times.
I like this teacher style video
I don't know the first thing about diesels but this was a good video too start learning. Top notch work
Thank you Sir. This is the best diesel disassembly and diagnosis video on TH-cam.
This makes me respect how easy it is to work on Honda motors
erick b yeah guess what- 35+ hours just to do head gaskets on 1 of those lb7's that don't even include bottom end!! I've done 6-7 of them already.
@@ppump24valve53 bullshit lmao. Takes me 12 hours beginning to end for lb7 headgaskets with hand tools.
I love videos like this. Thanks Wyatt for making it.
I absolutely do not like anything chevy related, however I enjoyed this video. You did a very good job. Almost like a professional tutorial. Very good job young sir.
I don't even have a car, but this is the video i want to see if i ever own something with an LB7. Loved it!, really enjoyed watching it.
Hey bro. I am very new to the diesel world. So say that thanks for this video really helped me understand the LB7 motor. Thanks again!
Extremely helpful! I fast forwarded to my question at hand and you saved me a lot of time… Thank you!
New to Diesel world, probably one of the best tear down videos that I have seen so far. Great step by step approach, keep up the great work!
I want to commend you on your video. Very informative and extremely nice to see a video without foul language that the kids can sit watch as well when they are wanting to learn about mechanics. A+++++++

Your video was very helpful thank you for a real complete video on this whole engine.. There are no videoa on upper oil pan as you showed here
If you keep doing vids like this you will do very well on youtube mate very knowledgeable for someone so young !!
You like to post at 3am to?
BoostedBoiz conspiracy
Notice me senpai
BOOSTED BOIZZZZ
Wait, Where is the BoostedBoiz Verification? Has youtube removed it?
Viewing no idea but that’s deffo them
Great video! Very detailed and I am sure this will help a lot of people for years to come.
Damn. You really know your shit. I just thought you were the goofy kid in the back of the boostedboiz videos. Respect. Subbed.
Ernesto Lugo he made boosted bois better. 100psi tested boi.!
best LB7 disassembly video out there!
doing this tomorrow for the first time thank you for making this great video
Love watching ur in depth vids! Great to watch a guy who knows what he's doing and not just " send it" lol
A five to six beer project.... instantly earned a sub, lol!
44 people said no ? Why ? Great information thank you amigo . I have an lly and had to do all these deletes and the wherly custom y bridge and set up and a few other minor repairs and new injectors. I started doing it with engine in truck but I have a severe OCD. And took the engine out to clean and better see what I needed to do and this video helped alot thanks again
Great video. Your content quality is getting a lot better!
As soon as I saw the PBR in the fridge I hit the like button 😂
Awesome video man, thank you
The same Jerry that was with Virginia here in Manteca california?
Thats amazing. Seein how diesel oil comes out i always thought a diesel would bebfull of black gunk and carbon, that motor is really clean
pretty creative intake on that motor. It's nuts how little room there is under the hood of newer vehicles to spread the motor out. I think some of the compact packaging is for quick install on the assembly line also. thanks for the video Wyatt I enjoyed this a lot.
You're the man !!!! Very professional work! Thanks
Dang ...nice job on editing this video...and Damn I can believe that tiny broken pin leads to no oil pressure and a toasted engine...great video and looking forward to the rebuild

As a fellow mechanic, I can appreciate just how ugly those motors really are, like you can barely see the heads... Great video man was a pleasure to watch.
Exciting stuff man can’t wait to see it finished! Hope you’re ready to tear into mine soon it’s gettin grouchy just rolled 290 yesterday
We just finished up a bad ass LB7 pulling truck engine. We cut a key way in the crank shaft. Gets rid the bullshit pins
Can you please give me some pointers on cutting this key way in oil pump shaft & the crank? Much appreciated.
Production quality my dude. Gettin it 💯
Nice!! Thanks for this video it's different and interesting!!! Great job! you took it all the way down
respect mate thought you where jusst another honda fan boi haha me think wrong
And so what if he was he makes power with Honda's a. Honda fam boy usually dosent boost it to 600 700 hp they slap a dart can on it and call it a day
Amazing how to video man!! Love the videos!
Love the video bro. I used to do he's machinery so love me a diesel. But I love a Detroit. Nice sign 9 1/2 that's sick. Love the diesel content, keep up the great work bro
love this style of video keep up the good vids
Your video is a life saver.
5-6 beer project. Last time I did that I forgot where I put a bunch of the parts! Hahahahaha!
Wow! That's sad. This guy can't even handle 5-6 beers
i lose them sober...
Toke ha!
Bud Light???? Well if you are not going to drink beer then nor will I :)
You need to pump them numbers up.
PBR!!! Highly underrated beer..
Thanks for the information this should be very helpful with my lbz to lmm swap
Very informative video. Can't wait to see more Duramax content. The pin that was broken. Is there a pin upgrade for the engine or do you have to go with the factory pin.
5-7 beers to watch... we have a duramax wizard. i will never attempt to rebuild a duramax to many bolts lol. great vid tho 👌

Badass video very helpful !!!! 👌👍👍👍👍thanks
I NEED MORE COWBELL!!!!! Great video
Nice job. Now for a duramax rebuild video.
Awesome job on video very informative
Great video Wyatt! !!
good vid dude, keep them coming
Yes. Needed this video
Excellent video!
Extremely HELPFUL Video..... Thank You! Question though, How many Miles were on this DMax?? (Please keep the Great video's coming)
Bro!!! You definitely need the Milwaukee impact set!! Leaves more time for beverages.
these two wires need undone too,,, Haha... that's some funny shit... but this really is a great video and the very best i have found on the internet this guy really is one of the best ...
How many miles were on the motor?
If you keep doing videos you’ll have 200k subscribers by the end of 2018
Does the upper oil pan have bolts holding it from inside the bell housing?
California? What I'm trying to find out? Did you ever find the answer to your question? Thanks for the reply back.
That's a lot to remember. It must be annoying to have a wreck motor because of a tiny cheap pin broke. Also even if you notice the oil pressure has gone I guess it would still cost a lot in labour (sorry English spelling) just to fix the dam pin. Good video bro, you have a good mix of content
This is what you call a major design flaw. They needed a hardened steal key instead.
I have a 2003 lb7 and it just randomly lost oil pressure, it only has 135,xxx miles on it, it's a learning process for me and working on diesels, I did the injectors myself, but how common does the oil pumps fail on these or would it be something else, and this video helped me alot cause I can't find another video where they are removing the oil pump or even talked about any of that,
And another question on the broken pin that spins the gear, how would you fix that if it's broke off mine
Duramax oil pumps are extremely simple and reliable and rarely fail its more likely there is a problem with your stepper motor in your gauge cluster.
Check your oil pressure with a mechanical gauge or use the squirt method. ( loosen up the oil pressure sensor while cranking and pull your fuel relay to prevent it from starting)
These remind me of another pain in the ass that was the Perkins TV8.540M, a marinized tractor twin turbo diesel. The cooling system was a haphazard design, and required frequent service or else you had to buy expensive aluminum housings. Just changing the raw water impeller and removing the sea grass from the tube bundle heat exchangers were excruciating projects. Assembly, like this one was critically sequential, or else..
some GREAT INFO 👍👍👍👍
I've got a fever and the only prescription is MORE COWBELL!
Keith Lamp 😂😂😂 I'll tell you what it's hard to find good background music that's the only downside to this song
