Re: If it weren’t for bad luck

That there is a no fun situation. The top picture is definitely piston chunks along with the circlip pin retainer. I'm not sure I recognize the pieces in the bottom picture. Do any of those pieces besides the wire retainer stick to a magnet?

Damage like this can be caused by insufficient ring end gap. It looks like the pistons have dry film lubricant coating. They're likely not cheapies. Did the noise start just after a blast on the throttle or just after a coastdown?
