I was about to say I think this is one of the few videos i didn't get to see the deck side of the heads. Plus I saw what looked to be a dented inwards sleve, like it got hit just enough to Bend it slightly off the main cylinder bore. It was number 7 or 8 I think right next to the bent oil squirter that was holding the cam back from coming out. I've not had a whole lot of experience with the gen 5s, but I'd say this one got some heavy detonation at 7k or so. Can't lean them out to much or put to much timing into them. I always like to leave them just a little fat and and go a few degrees under what the engine really likes to stay safe. Unless you just don't care throw the moon tune and go. Sometimes you can get away clean with that, or you get something like this. I'm not saying it was a tuners fault nor the tune it's self that caused it to let go. She might have had some valve to piston contact, over reved, detonated maybe a combination. Possibly another object could've let go to set this mess into its destruction lol.

Change the oil early and often helps a lot. If you don't do short trips all the time, that makes a huge difference too. There was a video by Engineering Explained where he visited Mobil 1. They put 500k miles on a 2014 or 2015 Silverado 5.3 and the engine looked amazing when they tore it down. It was a highway simulation which helped. If it was a short trip simulation with cold temperatures, the engine would look a lot different, especially doing 20k mile oil change intervals. It would have been covered in sludge inside. kzread.info/dash/bejne/nmGuptZydqqwmZs.html

I think this engine suffered a failure due to detonation, as opposed to excessive RPM. The marks on the cylinder wall at 7:30 clearly look like those that would be created by the corners of the wrist pin bouncing of the cylinder walls many times as it was whipped around by a still intact rod, after the piston had separated into its individual molecules. The rod broke shortly thereafter.

I dont think it was detonation... It probably pinched a ring, from excessive heat in that cylinder, and popped a ring land... You know the rest of the story once a chunk of piston is loose in the cylinder. Today's engines run fairly tight ring gaps, and they really NEED to be opened up if the engine is going to be producing much more power than what it came with stock. I have a feeling that this brand new LT engine was NOT opened up to have this done when the "tune" and "extra parts" were added to it. Ka-blamo... 💥

Got a 2009 avalanche with the 5.3 put 216,000 miles finally the lifters are stuck.. fixing to remove the heads and replace them 😮‍💨

Same oil pump in my ZL1 with the LT4 - variable pressure for mileage, electronically controlled where if you floor it, it ramps up pressure. GM had lots and lots of issues with them in the '17 and '18 model years where the pump housing would crack, completely dropping pressure to 0 and throwing a warning on the dash. As long as you shut the car off pretty quick, it was a fairly simple fix under warranty.

My father has a 2009 Silverado 5.3 that just rolled over 280,000 miles. It’s never been opened up, although it’s near the end of its life, it’s got a bad rear main and both valve cover gaskets are almost gone. With that said, it still runs smooth and has no misfires. I’d love to see the internals on this engine, as I’ve done the maintenance on it since the day he brought it home. It’s had oil changes religiously done at 5,000miles.

Thanks Eric. I recently found your channel and now I'm binge watching. And I subscribed. 🙂 This may already have been mentioned in the 935 earlier comments. Re the trouble you had getting the chain off the cam phaser at around 11m30s in, I saw a video of DOD delete on a 5th gen L83 engine. They inserted a rod behind the oil pump at the top right side, between the pump and the right hand run of the chain, and depressed the left run of the chain in the middle of the chain tensioner. It looks as if 5th gen has an improved tensioner that doesn't break. It's curved and springy and the force straightens it so the top end rises in the guide at top left above the oil pump, allowing a pin or a small Allen key to be inserted through holes in the guide and the tensioner to hold it retracted. Then there's enough chain slack to remove the phaser. Maybe this is in the GM workshop manual, I don't know. The LT looks like a great engine, but it's direct injected and still has DOD 💣 I read that the LT engines in Australian Holden Commodores from 2014 had the DOD disabled or deleted, not sure which.

Lots of potential in these. The heads are massive in terms of flow potential. What seems to kill these is the oil pump. GM changed the design and while massive, it's not as "user friendly" as the previous generation pumps. This was also when GM shifted to 0W20 engine oil and added piston cooling oil jets like you typically see on diesels. They are pretty robust, but they're not indestructible

Tie bar lifters, bigger capacity oil pump, new rings because I hate the "low drag for better mileage" crap and oil consumption. Who knows maybe it'll need something in another 60k.

Problem is they're still trying to recoup their losses from 2009 and they're doing it in the worst way. I left GM because they kept reducing their warranty labor times for very complicated jobs and they would refuse any attempt for techs to get more time. They also use lower cost components in their engines, hence the issues they're having. I had to replace one of these engines in 2017 for a rod knock on a truck with just over 6000 miles.

All the ones I've run on 5w40 seem to not have any DoD lifter or pressure issues even 100k

@@JohnEvans-ct6mz I worked for Volvo and as shop forman for 18 years, I can honestly tell you the whole shop has seen a total of three bad engines. One blew a radiator hose, kept going and two were in floods. I have friends that work for Chevy, Chrysler and Ford. Nothing but horror stories, engine after engine. A guy has a Ford Raptor and is on his 3rd engine at 15k miles. And yeah, warranty time does suck, but you have to be creative. Many opps aren't being charged for on a lot of jobs. Many shops are going strictly hourly, no more flat rate, so even the slackers get paid the same as Master Techs. And that's not right.

Legend has it that spring still hasn't come down.

Let’s see a Honda gold wing engine. That’d be weird.

Where are you gonna find a non working Honda goldwing engine ? Those owners are ocd about maintenance, don't abuse their equipment, & Hondas are dam near indistrucble !!

The pistons in the Gen 5 have the same issue as Gen 4 where they develop cracks in them.

Seemed like a bad injector would be a more likely cause. He never mentioned that the engine was on boost.

@@karlschauff7989 did rich injector cause hydrolock or lean injector cause burnt piston? I've noticed on other teardowns, these LS type engines when hydrolocked, rods bend significantly (like forged do) before they break . Some piston pieces should have obvious burn (and impact) damage if run lean.

Hi. I've been looking (searching) a video of you tearing down a 2019 (or) any year, Corvette Z06 engine. I'm a member and I think I did a substantial search. Love what you do and how you do it.

Awesome teardown of the block. My 07 silverado LS 5.3 is down. My mechanic says am looking at $3600 to get it going again witch means new lifters,oil pump and camshaft. I pray my engine is good enough to come back alive. Your teardown scares me but I am hopeful 😁

With all due respect, you look like a Midwest Adam Sandler

Hypereutectic piston + detonation = what we saw here..... My money is on a bad tune!

I used to have 4.0 4Runner. Interesting in seeing the tear down,

Too many onions added to the external mix (compared to the OEM design spec) AND then he gave it THE DOCTOR! So something had to give. A respectable result and a reminder that everything has a design/engineering spec and you exceed that at your peril!

My guess would be the "Highly Modified" had something to do with it. Not knowing if Mike has added a shot of NOS to this engine?? Or perhaps a Turbo (s)?? Or some other sort of "Power adder" Because my first guess would be that the end gap on the rings in that destroyed piston was the first thing that went wrong. With the RPM north of 7-K (just a estimate) And when the rings got tight, That was the first step that lead to the catastrophic chain of events. And left Mike sitting on the side of the road waiting on a tow vehicle. I can't speak for how tight these Gen V engine's have there ring gap set on from the factory. However I can say this, even the high mileage Gen-IV engine's are still way to tight to be adding any boost to them with out opening them up. I can only imagine how tight they are on a lower mileage engine from the factory. If its anything like the rest of the engine, GM is doing a might fine job sealing up these new engine's for sure. They aren't known for there leaks like there earlier designs where, thats for sure. Alex, I'll take Ring End Gap for $500. Please.

In my experience as a Chevy technician I’ve noticed most Gen V 5.3 and 6.2 engines have those odd little grooves worn into the pushrods. I’m not sure exactly what the pushrod is making contact with to make those grooves, but I’ve been told it’s normal and that it’s nothing to be worried about when tearing one down!

These engine giblets would make a great Christmas gift.
