The title of the thread is Don't ask me how OK TinCup, I won't ask you how but I'll take a guess that it was accidental damage when the Piston hit the concrete floor, directly followed by a lot of cursing.
My Phaeton engine is bored at .125" over and it has over 90,000 miles on it and still going strong. I agree with Chuck, "nothing wrong with .125" JMO
Good Day!
