A and C Note I said piston plug or other related part, I was disputing overhaul techniques being the problem and suggesting a parts issue was the cause.
I agree probably not the piston plug, more likely the composition of the cylinders or the rings.
I'll bet the cylinders that had the lip causing the plug wear were the front two.
