[QUOTE="BLACKJKU, post: 430907, member: 18221"] If it has good oil pressure and doesn't smoke then it doesn't need a rebuild. I've heard of those engines being torn down with 500,000 miles on them and the cylinder walls still have the cross hatching on them. There alot of them with over a million miles on them before needing a rebuild, just don't over heat it. I'd adjust the valves and at least replace the rear main seal. Check the tappet cover gasket and if the rubber feels hard i'd replace it also. It can be done without pulling the IP, i've done it 3 times already on engines. This stuff is easier to do with the engine out, When you have it set at TDC for doing the valves put a paint mark or other permanent mark on the crank pulley and timing cover for future reference. It's a PIA trying to lock it in TDC with the engine in, with the mark just line up the mark and your good to go. [/QUOTE]
