To the S65 experts out there: Any unifying theme on these motors where the rod is simply letting go? Spun rod bearings aside, the bottom end of the S65 looks to be pretty stout 'on the hoof'. But i've seen and read about a good number of cases where the motor vomits a rod and/or melts a piston. Detonation? Running the motor too hard before its up to operating temp? Just curious, don't mean to make a mountain out of a molehill.

Edit: How about the heavier recd' oil on a motor with such tight clearances? I profess general ignorance to the S65 outside of big picture knowledge. Curious to hear your guys' perspective.
