Скачать или смотреть SEIZED & BLOWN UP Jeep 4.0 Straight 6 Teardown. How Someone RUINED One of the MOST LEGENDARY Engines

Today we teardown one of the most well loved engines of all-time, the Jeep 4.0L Straight 6. This specimen is out of a 1998 Jeep Grand Cherokee, and judging by the oil pan, something undesirable has happened inside the crankcase. This engine was torched out of a scrap car, and unfortunately I don't have a history or know mileage.
So what happened to this super reliable engine that caused it to destroy itself? Was this operator error or did this have bad maintenance and did anything survive this failure? Thats what this video will show.

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

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!
