Want to see a particular engine torn down? Check out my 50 other teardowns from Cummins to an LS7, and from Rotary to Ram Ecodiesels. Check them out here    • Blown Up Engine Tear Downs! A collect...  
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines.

If you're interested in buying parts from these engines or the other engines I've torn down, email us at [email protected].

In this video I tear down TWO Gen4 GM 5.3L V8's. The first is an Iron block LMG from a 2007-2009 Tahoe, Silverado, Yukon, Sierra, Suburban. These are non VVT engines, with DOD/AFM. This engine was clearly not repaired correctly. The second engine is an LS4 which is an aluminum Gen4. The FWD engines never got VVT. This too has DOD/AFM. Two different possible causes for failure!

As always, I hope you enjoyed this video. I appreciate all of the comments, feedback and even the criticism.
Catch you on the next one!
