YOUR RIGHT, it was the valves! runs AWSOME now, barely know it is running when you are sitting in the truck! but that mark was a bitch to find on the flywheel. now it is time for the spring over and 37x17" mtr's! thanks for all your help

what do you mean, these are arguably the most reliable trucks in the world if taken care of properly

Yes but when you abuse them

THis thread looks realy old.. but I have the same problem.. blown head gasket.. was running on 4 cylinders.. ran rough but ran.. now rebuilt head all back together and exact symtoms. can get it to start if you press the gas alot.. and gota keep the rpms going.. then just wants to die out after 2 minutes of running.. seems to be abit hotter than before too. i let it sit for a few minutes then it pops on again.. then runs rough and weak.. then dies...
