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. Here are some of my favorites:

Today we tear down a supercharged 5.4L V8 from a 2002 F150 Harley Davidson. This engine is a detuned lightning engine that ford stuffed into a crew cab truck for only two years.
This engine is a complete unknown as far as condition, miles, etc. I bought it as is for a teardown and the parts value and today we tear it down to see what's good, and what isn't. This poor engine has seen some neglect, and has suffered some pretty common problems for these engines.

Why do I do this? I own and run a full service auto salvage business called Importapart. Part of our model includes buying broken, bad, blown and otherwise unusable as-is engines and dismantling them to salvage the good parts. We do not rebuild 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!
