Is this the first teardown you've seen on this channel? Wondering if I've torn down your engine? Check out 110+ of my other teardowns here:    • Blown Up Engine Tear Downs! A collect...  

My name is Eric and I own and run a full service salvage yard in the Saint Louis area called Importapart. Part of our model is stripping down blown or core engines and salvaging the good parts to resell. We do not rebuild engines, we merely sell parts to those that do!

Today's specimen is one of my lesser favorite engines ever produced, the ford 4.0L SOHC found in the 2002-2010 Ford Explorer, Mercury Mountaineer, 05-10 Ford Mustang, and 2005-2011 Ford Ranger.
Note: Not all 4.0's are like this, this is the particular 4.0L That I do not like. Earlier 4.0's are much less failure prone in my experience.
There are several reasons to dislike these engines. and most of those reasons center around the timing system design and component material. Its quite clear why these engines fail and the labor to repair far outweighs the value of many of these vehicles, and they sadly end up at the salvage yard.

I really hope you enjoyed this teardown! As always, I l love all of the comments, feedback and even the criticism.

Catch you on the next one!
