Every week I post a new engine teardown. These are engines that have failed or thought to have failed and we try to discover what happened, why it happened, and what parts survived. Here are a few of my favorites!
8.0 Dodge Ram V10 WORST ONE EVER! 8 LITERS OF DESTRUCTION! Dodge Ram V1...

Ford/JLR 3.0 Powerstroke BAD 2017 Range Rover Sport 3.0 V6 Die...
Today we tear into a 3.0L Duramax Inline 6 Turbodiesel from a 2020 Silverado 1500. Known as the LM2, 2020 was the first year this 277hp, 460ftlbs of torque 6 cylinder is the first half ton diesel GM has made in decades. This particular engine died at JUST 45k Miles! STILL UNDER WARRANTY? Right? These trucks come with a 5 year, 60k mile warranty so how did this engine end up on my stand? Well I believe this failure was NOT covered by the manufacturer. Not all failure scenarios are the manufacturers fault. Abuse, Neglect, Modifications are some of the reasons a claim may be rejected.
In this case, this engine was brought in with the torque converter stuck on it, completely locked up. Due to its design, getting the engine to turn over to get the converter off was quite laborious, which is likely why whoever replaced the engine opted to replace the torque converter with a new one.
So WHAT HAPPENED? This engine has TONS of damage, but what caused this failure, and why do we think it wasn't covered?
Why am I doing this? My name is Eric and I own and run a full service auto recycler. Part of our model includes dismantling bad, blown and core engines to salvage the good parts for resale. 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 all on the next one!
