Teardown GM L92 6.2L Escalade Denali Blown Engine, Worst One Yet!

Glad to know that you're not going to lose money on that pile. I just discovered your channel thanks to my brother and have been enjoying your engine tear downs. If you need helping moving parts you may want to call Ray Zalinsky the Auto Parts King. He sells car parts for the American working man. Because that's who he is, and that's who he cares about.

[@rynechristesen2392]

Good stuff man! I’d like to imagine a lot of these issue stem from lack of maintenance especially with Truck/SUV variants. How many people I’ve met that didn’t realize oil needed to be changed as often as it does is scary lol

piston, piston, piston, wrist pin. lol. and another dropped seat. I know you look to turn profit on the parts with these cores, but my enjoyment is seeing just how bad an engine can be. can't wait for the next disaster.

Please do the AMG one. These videos are great. No BS, straight to doing. That block needs just sleeves and it's good for 1000+ HP.

It's hard to believe that GM still has not fixed this engine. I had a 2012 Denali that started having lifter problems at about 40,000. The dealer rebuilt the heads twice and then finally put new heads on at about 60,000. Luckily, California has a Lemon law and GM bought it back. My next GM (2016 Yukon) had a 5.8 and never had any issues. I upgraded back to a 2022 Denali that the engine failed at 14,000. GM shipped out a new crate engine and have not had any issues since.

[@PureCountryof91]

So much for the myth of the infallible LS.. that was some carnage.

[@alltheboost5363]

You should get a hold of Texas Speed cuz that engines not junk to them... they resleeve a lot of the engines anyway. if the cam journals main journals are all good and the deck surfaces are good. that's a perfect candidate for a 2000 horsepower engine. You may be able to get a little bit more than scrap price and they could save money by not using a perfectly good engine.

From the look of the varnish all over that engine the oil was not changed regularly. It amazes me why someone buys an expensive vehicle like an Escalade then won't spend a few bucks every few months to properly maintain it.

Can't this block be used for a re-sleeve? Some of the comments for the LS7 block were noting that you could weld the crack in the block and just replace the sleeves. There may be more value to these blocks than you think. Definitely keep your ebay link on your drop down. It took me a hot minute to find your ebay store.

Caused by pre detonation! Using too low of a Octang gas along with a non Dexos 2 oil. Dexos found in a study that too much Calcium in the engine oil caused Pre Detonation and catastrophic piston failures. That's why Dexos 2 is now the new rating.
