STILL A PROBLEM? 2021 Ford F-150 5.0 Coyote Engine Replaced at 65,000 Miles With Good Maintenance

Today we are tearing down a 5.0L Ford Coyote V8 out of a 2021 F-150. This engine was replaced at approximately 65K miles, but why? and why wasn't this done at the dealership? This truck has excellent maintenance history with oil changes every 7-8K miles always done at the dealer. With such low miles, what could possibly happen to the engine to warrant replacement? Will what we find affect many more engines and become a big problem for Ford, or was this just a freak anomaly?

This being the first year of the gen4 coyote, has a few different systems including a belt driven oil pump and cylinder deactivation, our favorites! This engine shares much of the short block with the Mustang GT, and produces 400hp and 410lbft of torque.

Why am I doing this? My name is Eric and I own and run Importapart, a full service auto dismantling business. Part of our model includes buying blown up and bad engines to dismantle for parts. We salvage the good, sellable parts and recycle rest. No, we don't rebuild engines but we do sell parts to people who do!

As always I hope you enjoyed this video. I love all of the comments, feedback and even the criticism. Catch you on the next one!
