1977 GMC Engine Removal Chip Chebuhar 10-21-09  
I have a 1977 GMC Motorhome. Olds 455 motor. No idea mileage on it. When I start it I hear a slight knock. Goes away very quickly. Good oil pressure, runs smooth, power good, no temp issues. Mechanic thinks piston skirt (spelling?) is cracked. Suggests I pull motor and tear down. Thoughts? Easiest way to pull motor on GMC?

Thanks - Chip

Before you pull an engine you better find the problem. With the tools out there those days, it easy to inspect a bottom end & piston. The pan should come out of there without pulling the engine.
