Mercedes ML550 M278 Bi-Turbo V8 Engine Teardown. Unavoidable Failure?!

For parts Email us at Importapartsales@ or visit ! Here’s weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. I’ve got over 150 videos of failed engine teardowns on this channel. This week’s teardown is a Mercedes Benz M278. A DOHC Bi-Turbo DI V8. These engines make 400-450hp and come in midsized and larger cars and SUV’s with the 550 designation starting around 2011. This particular engine is from a 2013 ML550 and is a core return from a local salvage yard. As such, I don’t have information like mileage or suspected failure. In this video I tear this engine down complete and try to figure out what went wrong and why, as well as what parts I can salvage to resell. These engines have a LOT of pricey parts so they are quite lucrative for the shop but those parts have to be good. Why am I doing this? I own and run a full service auto salvage busin
