RUINED Jeep Wrangler 3.8L V6 Engine Teardown After 286,000 Miles!

Today we tear into a 3.8L V6 from a 2009 Jeep Wrangler with an inspiring 286,000 miles! This engine is a core return from a local salvage yard which sold it to a customer to get this jeep back on the road. So after that many miles, what killed this engine? Lack of maintenance? Improper repair? an off-road scenario? Lets find out why this engine was replaced, and what parts survived the ordeal. The 3.8L V6 that debuted in the JK Wrangler starting in the 2007 model year was borrowed straight from the Dodge caravan and Chrysler town and country. A Minivan engine you say? Well even though these engines don't get the same love as the iconic 4.0L Inline 6 that they replaced, I personally think these deserve quite a lot of respect for being simple and inexpensive to own and maintain. Why am I doing this? My name is Eric and I own Importapart. A full service auto dismantler. Part of our model includes dismantling blown up, failed and otherwise bad engines to salvage the good parts. We do not rebuild engines, merely supply parts to those who do!
