[QUOTE="76GMC1500, post: 1142706, member: 73139"] That chip isn't really anything to be concerend with. That piston appears to be OEM, but the chip appears to have been there for a while. Maybe the cylinder just chipped and the piece left through the exhaust port without doing any damage. The .30 below spec will certainly cause slap. What about this rubbing of the crank? It should turn free. If the crank is good, I would replace the piston and keep doing what you're doing. I would expect lack of lube wear to be higher on the skirt, but you never know. [/QUOTE]
