Well I finally got around to pulling my engine apart to find out what happened.
The backstory I was returning from an event somewhere when about a mile from home I hear a awful noise and loud clatter. I had no loss of power and drove the rest of the way home. Rented a trailer and towed to my Mom's and the engine finally got pulled out last year. Time passed and I finally startred to pull it apart. I had been thinking possible connecting rod bushing problem at the wrist pin as I did not rebush those at the time of the rebuild. Well here is the results. Question can the washer be machined out of the head? Is the piston still usable? Opinions welcomed. Attached image(s) |

This is/was a fairly fresh rebuild. Hardly any miles on it. It was just starting to get broke in. Pistons and cylinders are Euro and no damage to cylinder walls cross hatching still there. The damage to the piston comes nowhere close to the ring lands. I think I am going to try and get the washer removed from the head and go from there. Right now it will be a while before it goes back into anything that is roadworthy.
