Tearing Down A DESTROYED Mitsubishi Evolution 4B11T Engine. This Thing Was A TICKING TIME BOMB!
For parts go to www.Importapart.com or www.pro-rebuild.com
Today we are tearing down a Mitsubishi 4B11T from a 2008 Lancer Evolution that was installed in a Ralliart I bought at the auction, wrecked. Copart advertised this as "engine start program" which means the engine ran.... HOWEVER as you can see, even a blind wombat would have noticed the GIANT HOLE in the block.
So how did this happen? How did the engine, which was at one point bad, end up in another WRECKED car, and bad again?
In this video, I'm going to tear this jaded 2.0L Turbo 4 cylinder engine down to see just what happened, and hopefully get a few parts to salvage and cover the loss of an expensive engine I didn't get.

Every week I post a new teardown video of a blown up or suspected bad engine. Check out a few of my favorites!

Why do I do this? My name is Eric and I own and run Importapart, a full service auto recycling business. Part of our model includes buying and dismantling core, bad, and broken engines to salvage the good parts and recycle the rest. We do not rebuild engines, merely supply parts to those who do.
As always I hope you enjoyed this teardown. I love all of the comments, feedback and even the criticism. Catch you on the next one!
