For some reason I don't remember the pins to be floating when the motor was originally built but I could be wrong on that. Perhaps they got converted at some point.

I do remember that very early on during a rebuild found several pins blued. The machine shop honed the pistons/rod (not sure which) replaced a couple pins and cleaned one or 2 up. Never had a repeat problem until now.

These rods have seen 6800 rpm far too often - it might be a good omen for them to fail like this just so that I replace them with a reasonable rod.
