6.6L Duramax Disassembly

In this video I show you from start to almost finish how to disassembly a 6.6L Duramax engine. The engine used in this video is an LB7 engine but is relatively the same to newer versions of the duramax. If you have any questions or comments please leave them below.

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.

Can you please give me some pointers on cutting this key way in oil pump shaft & the crank? Much appreciated.

[@zackk695]

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

[@kevinc9006]

This dude does good work

[@stevewaclo167]

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!

[@TheSRMproject]

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 😓

[@ynotitsme]

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...

[@TheBenLG]

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

How many miles were on the motor?

[@johncasor9698]

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 ...

[@Garth2011]

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.

[@mxdirtrider2]

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,

[@mxdirtrider2]

And another question on the broken pin that spins the gear, how would you fix that if it's broke off mine

[@Dylan_LB7]

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.

[@ne2i]

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)

you did a awesome job.... i thank you !!!

[@HUBBABUBBADOOPYDOOP]

Give everything a good bath. WD-40/#800 Emery cloth with shoelace the crank journals, spray it all down with brake cleaner, throw in new crank & rod bearings, rings, gaskets, and soak the injectors in cleaner and blow out. Flush all oil & coolant passages. Reassemble all. Send it. Quit being so melodramatic- the bearings did their job; the crank is way tougher than the bearing. All is not lost.

[@Giftied]

good vid dude, keep them coming

[@gcrauwels941]

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..

[@ToXSicK1340]

Badass video very helpful !!!! 👌👍👍👍👍thanks

[@sethhill7929]

My Duramax oil pressure gauge just started fluctuating today. I watched the video until the end when you mentioned the oil gauge. What would you recommend my next step to be?

[@randallrogers8183]

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?

[@ynotitsme]

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...

[@justinrems1]

Good work but a little tip, dont hit the wrench with your hand to break it loose. Your going to destory the nerves in your hands over the years. Very hard habit to break becuase of how convienet it is but its for your own health. Keep up the great work.

[@techy937]

Does the upper oil pan have bolts holding it from inside the bell housing?

[@ynotitsme]

California? What I'm trying to find out? Did you ever find the answer to your question? Thanks for the reply back.

[@Qman06]

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!

[@jhurley12]

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.

[@ynotitsme]

@@jhurley12 can you please give me some more info on this topic as I believe this pin just broke in my LB7. Thanks for the reply back.

[@gmauldin6574]

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.

some GREAT INFO 👍👍👍👍

[@lvnlyfe843]

Awesome job on video very informative

[@darthvader8433]

We haven't see the Duramax in Australia yet, AFAIK. Though we are starting to get RAM, F150/250 and will probably get the Chevs if we don't already. Are the Duramax diesels sold as crate motors or short motors like the LS motors? Have all American cars now gone to the metric fasteners? I'm guessing this happened when the modern (from LS1 era onwards?) came in. Have only heard of one conversion here with the Duramax, went into a GQ Patrol. Lots of grunt apparently, but a pig of a conversion.

[@benhuff2600]

I have a 04 Lb7. Had injectors and turbo go out last year. After a fresh oil change I have normal oil pressure for about a month or two. then as the oil loses viscosity I’m guessing I lose oil pressure. when at idle it’s around 5-8 lbs and the warning starts dinging. Also after about a month it starts leaking oil out of the overflow tube like it did when the injectors went out. So any ideas on what that could be. Worn bearings? Broken pin like yours? Oil pump? Or faulty injectors

[@shanek6582]

My lb7 truck, first noticed the heater blowing cold air, thought it was the thermostat but checked the oil and there's coolant in the oil. Have I got a blown head gasket? I love my truck and would rather fix it but this is a big project, If a shop only charged $2500 or so I'd get it fixed but I couldn't afford much more and might try it myself. I'm worried it might be something other than a head gasket though, any advice? Thanks.
