I bought this truck with a new in frame from a dealer. Had 1year/100k warranty. Got 115k before it blew a head gasket, technically out of warranty. I got the dealer to eat the labor, I just had to buy the parts. Head gasket # 2 went at 89k. Head gasket #3 went at 101k. At this point I said to hell with it & bought another kit & head & did the work in-house. That time it went 121k, when I pulled the head #2 & #3 liners were cracked. When the liners were pulled, there was a crack in the deck between 2 & 3. The motor was never out of framed, if so, might of caught a internal crack and saved a lot of headaches. I’ve personally never had this much problem with a motor.
