I've seen damage like that before in a diesel engine. Why I was the one that caused it. April of 97 my mom had a heart issue while in the hospital recovering from surgery. I was in Kentucky at the Tennessee line when I found out. I told my boss that he better let Illinois know that speed limits weren't going to work for me that day. 4 hours later I was home. It was a distance of just over 370 miles. I had burned pistons 2 and 4 and cylinder 1 had swallowed the intake valves. I pegged the pyrometer at 1500 degrees. Boss all he said was overhaul time and we are going to make her able to take anything thrown at her. Yeah he did took her from a 444 Cummins that was already hopped to around 500 to 850hp. She literally could pick up the right front tire off the ground under heavy loads after the overhaul. This engine was hopped up by someone who didn't have a clue what they were doing.

As a further comment on what my boss said when I got to the yard that day. He went nice to know that my 20k in donations to the Illinois state police foundation was good for something besides a tax deduction for all those years. I had 2 escorts in Illinois running in front of me. When I hit the line the first one said we're aware of your problem you set the pace and drop the hammer driver. We will replace ourselves as needed to get you home. So I proceeded to put Rose as that truck was called into 13th gear which was .5 to one in ratio and turned 3.55 rear end gears. Then slammed the throttle to the floorboard jerking out the manual throttle to overfuel her and let her rip. I topped her out at 110 before the police said that was fast enough. Why they were running out of speed. I still had 300 rpm leftover. But running that hard that long literally cooked the entire engine.

@4:13 That is the Vane Position sensor module. The Duramax uses a tiny Linear Variable Differential Transducer (LVDT) to monitor the turbo vane position in real time. It uses a 555 timer circuit to induce a fixed frequency into one set of coils while reading the output on another as the conductive shaft moves in between them. It's like two tiny AC transformers but you change the mass of the core causing the output to change. They use them everywhere in aviation, the things are stupid reliable and silly accurate.

Happens when you have an injector failure. The injector "hangs" (doesn't close) and unmetered fuel pours into the engine and the injector turns into a blow torch. Usually this happens due to bad fuel or water getting into the injector and causing it to stick/fail. Another thing that does this is poor tuning where again, too much timing (fuel) is injected and likewise melts the engine. Of course since the injectors weren't shown its just my best guess based on seeing more than one melted engine. Usually though there's melt damage on the pistons as well. So if it's in the heads only, the initial failure was high EGT (exhaust gas temperature). Just a guess

As a former Duramax master tech (no longer with GM), it hurt my heart to see you take that exhaust apart so easily. To do that in vehicle, let's just say, it's a lot of work. These engines are unbelievably awesome but extraordinarily complex. Once you really know what's going on, you can tell if someone has been into it before. Specific bolts are always left loose or wrong ones used. If you know, you'll catch it immediately. I think that engine died from a runaway after overheating. It all likely started from severe lack of maintenance and an eventual failure of a valve seat and basically everything else.

Came across yer channel recently. For me, totally fun and interesting. I have done 2 Duramax engines for rebuild projects in the misty dim past: an LB7 and a LBZ. Both were serviceable with no blown parts. It was "interesting" seeing a trashed LLY engine. Good job on the teardown! These silly things weigh almost 1/2 ton. I may have done the teardown in a slightly different order, but I think you fundamentally got it. Given you found mismatched bolts/nuts in different locations tells me the person who worked on this engine likely didn't know what they were doing or were rushed for time or both. I think your best bet is to put penetrating oil in the cylinders and let sit for awhile. You may have to work them "back & forth" a couple of times before they pop loose. Would like to have met the "mechanic" who left a broken stud in the head just so I can recommend no one ever take their vehicle to him/her to be repaired. Not sure I would even trust this person to do a tire change...

Fun fact. If you look at the plastic turbo horn you pulled off, you’ll notice the opening is substantially smaller than the mouth of the turbo. This was the first year gm went to a veined turbo, and they were worried the trans wouldn’t handle the more instantaneous power. So they made the turbo horn smaller to decrease Airflow…. Why they thought this was a good idea I have no idea but you now know why the lly was known for head gasket failure and overheating.

GM and their design geniuses come from the same school as their marketing geniuses. Ever hear about how Michael Bay made them billions from the Camaro being the new Bumblebee and they gave him the original car for $1.00. Then the new head of GM came in and told him he had to give it back and then sued him and threatened to have the cops arrest him. This is the same guy that canceled the Camaro, discontinued the Volt, stopped Blackwing production after this year, and insisted the Silverado be 12% more expensive than previous years so that people equated price with quality. They do some colossal screw ups in design, production, advertising. They had the head of media relations on an interview with some news station and they asked her a out Zebra Corners parodies of their commercials, she said that she had never heard of them and they couldn't be that popular. So he told her that they had millions of views each video, she said that in the world of social media, that was nothing and went on to describe their commercial for the new C8 having hundreds of millions of views and said that those were the type of numbers you needed to generate to get on their radar. Clueless.

So I flushed cooling system well, removed radiator and found it badly plugged with fuzz/hay/dirt. Once that cleaned out, it’s never gone above normal even when towing 8,000lbs in 95° temps

It was probably some high schools kids truck had a “buddy” that knew how to do injectors and put bigger injectors with some sort of tuner and melted holes in the heads due to high exhaust gas temperatures and got that thing super hot to blow freeze plugs and not to mention probably didn’t have the right tools for the job

Directing all of the incoming airflow directly into a flat wall in the Y bridge. Then making it all do sharp 90 degree turns to get to each bank, then making it all make a sharp 90 degree turns again to flow down the log intakes, then sharp 90’s again past super sharp edged intake ports in the heads. It’s like Isuzu was still stuck in the mindset that “the turbo will force the air where we need it”. Leaving tons and tons of efficiency on the tables with these terrible induction designs.

looks like it was overheated badly at the end, explaining the lack of torque on the head bolts. frost plugs blew out then too. if those 2 coolant holes failed at thje same time, imagine the combustion pressure the coolant system was subjected to til the relief valve took over. i'd bet that engine was under a lot of load when it blew. i've seen heads with enlarged coolant holes, but it came from not changing coolant out and corroding them. never sen holes like that from baking. it's a first.

how do you oil the turbo in that application?

@@ben3989 Usually a power steering pump turned by a drill or just a gravity feed system. They're mostly just workbench ornaments so lubrication isn't the most critical thing, but some people have put them on gokarts and such before.

Could not believe that torched head! Worth the price of admission.

Wow Thank You and Happy New Year to you! 🙂👍

The injector with the butt connectors is to resolve a well known issue with stock harness plugs being strained on #2 (the one you pointed at with the connectors) and #7, the right rear cylinder. I have the factory GM replacement plug, and it comes with heat shrink butt connectors.

At this point the cylinders walls needs an bore job, just send it with the wirewheel and remove as much as you can, then penetrant to free up the rings. Thats what I would do

I would do the same thing, but the rust around the pistons is also a problem at it will need a lot of force to make them move. The rods and pistons will be junk at this point. But you may be able to save the block (will definitively need an overbore after that) and the crankshaft.

@@Fabien2626 piston dont touch the cylinder walls, rings do. And Im 100% sure the rings are trash, anyway you always put new one when putting a "new" piston in. The piston and rods should be fine if he dont hit them too hard

@@felixrobitaille8170 the pistons made contact with the valves, so the rods and pistons are dubious. Also the rust is so bad, I'm not that sure about the cylinder walls not touching the pistons... At least something that might have, at one point, been the cylinder walls is currently holding them in place.

Nice fuel bath LOL. Have enjoyed the laughs from the videos. Keep them up and ty

That Turbo is HUGE!! :)

I know how ya feel. Respect to diesel techs. I've been restoring a 25 year old 7.3l Powerstroke. It's a pain in the ass.

Damn! No piston McNuggets!? 🤷‍♂️

Nah, it takes a bit more to break a diesel reciprocating assembly.

best part about saturday. new engine teardown!

I watched some of the new videos then started watching from oldest to newest. It's been fun to see small changes. You got your hair cut (or brushed) for the videos. Started using engine stands sometimes. Now the head bolt cracking without the impact has started. Just awaiting the debut of blue and the careful wrapping of broken engine parts being placed gently on the table.

This must be the engine whistling diesel destroyed.

I was thinking the same thing!

Some pops and crackle coming through your VHF lav mic. Nothing major, but worth mentioning. Check the connection or Google a denoise/noise removal plug-in for your NLE

In my decades of working on gas, diesel, heavy and light equipment never saw a head torched like that one.. that's a first for me.

Wow very complex teardown I've seen. You did the right call.

Pretty sure that jumper harness and module you questioned was a boost fooler.

No its the vane position sensor on the turbo.

On a forum somewhere is a kid bitching or bragging about how he blew his engine. Everything should be sold as a core. It all needs to be tore down and inspected. Injectors, turbo, dip stick.

Thanks for doing it so we can see!

The most fun on these motors is the dissimilar metal issue Injector hold down bolt goes through about 2” inches of aluminum valve cover When it gets totally gagged up and snaps off the only solution is to air chisel the bolt area till it fractures and then pry the valve covers off Super fun doing it in chassis

LLY is the least favored Duramax.. they were the oddball and had weird overheating issues. LBZ was the most coveted pre emissions Duramax

thats what i keep hearing but my lly is great. had the 2001 lb7 and it gave me many issues. i love my lly. never overheated or had bad injectors just turned 184k. i have put a better intake on the turbo but never runs over temp even in nc mountain with camper behind.

i would take the lly over the lmm all day long. just saying. would love to have the lbz

It's called a dirty max for a reason.

Every time i watch one of your videos i want to run out to my local junk yard and buy an engine just to tear it down... I really enjoy your videos, and i don't know a thing about engines....

"I don't know what I'm looking at but I can see it" LOL. Like watching ur videos, informative, very well described and funny at the same time, ur a good presenter.............Mike
