well bad things finally happened to the WR. was making noise and running a little warm and then just stoped. cams galled heavily and piston scoured on intake side. wrist pin shows a little pitting/galling. had in fresh oil and no problems found so far. the only issue i have found is that a couple of the cam cover bolts were loose when i tore it down. not sure if this was cause or symptom. whats the feeling of the masses? without knowing what caused this i am hesitant to rebuild and repeat the problem. what should i look for? anyone else had this experience? what is the cheapest way to rebuild this?
