They're still good engines, takes time to get them near perfected like the 7.3 was and the cummins. The point of my post was that the duramax was a good engine. However, what in the stinkin world do radios, seat adjusters, steering shafts and just about everything else besides the injectors have to do with the engine alone? I'm talking the engine itself......not the rest of the truck that surrounds it
