I've made almost 200 videos tearing down blown up engines. Here are some of my favorites:

Today we tear into a very HOT engine. By that I mean, that the demand far exceeds the supply which is why these engines used are $5500-$7000 PLUS core charge, and why the core charge is over $1k! This is an L86 6.2L Gen5 GM V8 from a 2014 Cadillac Escalade. These direct injected, all aluminum V8's pump out a stellar 420HP. You can find these in 2014+ Escalade, Yukon, Silverado, Denali, Sierras, etc. Because of their extremely high core cost, its rare I get one of these in. As well, most of the cores I see on these look like this one, totally pooched! But why are they failing? Why do they fail THIS BAD? What caused this amount of damage? You'll have to watch the video to find out.
Why am I doing this? My name is Eric and I own and run a full service auto recycling business called Importapart. Part of our model includes dismantling blown up and core engines to salvage the good, usable parts. We do not rebuild or repair engines, merely supply parts to those who do.
I really hope you enjoyed this teardown. As always I love all of the comments, feedback and even the criticism. Catch you on the next one!

The wrist pin yelled "I'm free" and is now relaxing on the side of the road somewhere.

What it's not Saturday?!?! You spoil us. Happy memorial day!!
-
I can never get enough of your engine teardowns they are the most entertaining videos I watch and I always look forward to seeing the new ones
-
Two thumbs up for getting in "banana phone" "Beastie Boys" and "Monty Python" references all in one episode!
-
Some one watching this video : " a ha , now I know where the wrist pin that entered my windshield when I was cruising on the Highway came from "

I was a GM tech when these were introduced. Almost immediately they had problems. I had one give up backing off the delivery trailer from the rail yard. They didn't like when it got below 40° f . They constantly have misfires, the mechanical fuel pumps fail , the afm fails, the rings fail, the head gaskets fail honestly the only redeeming quality is a toddler can tear these down and rebuild them. Your bent push rod is most likely from a failed afm lifter...super common. I loved it when they managed to get wedged in the bore and you'd have to replace the 8 thousand mile engine because you broke your pry bar and slide hammer trying to remove a hammer forged lifter .

Never ceases to amaze me how COMPLETELY DESTROYED pistons and rods get when this sort of thing happens.

best part of Eric's vids! No Adds, No Filler, No 5 minute intro! So happy to not have to watch VPN commercials.

Ahhhh the old electrical problem. Yeah electrical. The escaping wrist pin knocked the alternator off :) For as it is written: "He who is without oil, shall cast the first rod". Compressions 9.4:1 :D
-
That's the beauty of a V8, if one of the connecting rods ejects itself, you still have 7 more!

I loved the "exploded view' of the destroyed piston.

Lots of folks these days just don't check their oil. My daughter (age 44) dropped by the other day for a visit. Said her car (an Infinity QX-80, 2014) was making a 'rattling sound' on cold start up. Checked the oil, it was FIVE QUARTS LOW. It holds six. I said, 'hey hon, when was the last time you checked the oil?' She replied; 'oh, the oil light never comes on when I'm driving, so I figured it must be full of oil'. Many people still believe the oil pressure idiot light is the oil LEVEL indicator light.

@22:13 Piston Nugget?! Nah man that's a full on Piston Tender, maybe even a Piston Finger
-
I'm going out to check my oil again.
-
I don't know what is so mesmerizing about a blown up engine teardown. But I love it!
-
Holy cow that was a lot of part numbers in the oil pan
-
You're nailing it, keep the great work!
-
As a retired, ASE certified GM line tech i always find your running commentary, as you're working, to be both amusing and informative. I agree this one, the "cause of death" is unclear. I'd like to see the results of an oil sample lab analysis. "Off the cuff", i suspect the oil became contaminated & the operator foolishly tried to "drive through it".

It did fix itself. It`s not knocking anymore.
