We run the mountains a lot. I mean A LOT. Most of the Detroit's only make it to 800K. Volvo is the truth, the way, and the life. The rod bearings don't even look worn, and the liners didn't look like they showed any signed of leakage. Pistons and rings looked fine. I didn't see the mains. And I knew I should have gotten some pic's, cause he's putting it back together so fast, it's too late now.
