did an In frame few yrs ago in our old
Kenworth low boy. Did basic inframe job everything went well , So now my driver has noticed a knocking sound again. So I looked it over An sounded like it was from top end. Dropped oil pan An started pulling rod caps off an wiggle each rod. I though maybe it had spun wrist pin on number 2 or 3. Well I noticed rod 3 was Lil tite to wiggle. Pulled the number 2 head off An pulled piston An sure enuff the wrist pin was blue An bearing done turned an1/4 turn in rod an seizing up. Also noticed liner an piston both had scratches up An down them An bottom of liner was cracked An leaking coolant in pan. I looked over spray jets An looks to still be in tack an not stoped up. So do I just replace the one liner rod piston an bearings for that one hole. Would like to know what caused this cause don't wanta see this again with this truck
