I really would check out the diesel page, though... there are probably hundreds of members there who could answer any question you might have on the 6.2/6.5 right off the top of their heads.

I know.I'll never hear the end of that. I have heard of some Duramaxx issues; there is a coating they used on the heads to prevent corrosion and some owners neglected to change the coolant when they were supposed to. It would eat through the coating, but thats on the owners, not the engine. 6.9s and 7.3s can calvitate in the rear cylinders by the same neglect -
