Just pulled the pistons out of my motor because of my cam wiping lobes off. What would cause the top edge of the rings to be razor sharp? Poor oiling? Also one of the rods does not move nice and freely on the wrist pin like the other 7 do. What would cause this? They are pressed pins. Its not super tight but the rod doesnt flop around as easliy as the others do. Will this hurt anything? Let the beer drinking commence now. My $700 Eagle Forged crank is shot. I dont think turning it .030 will take care of things either. Anyone need a boat anchor?
