GAAAAR Kevin, i knew u would try to beat me to it!

My guess is the bolts for the retainer for the piston rod backed off due to wrong torque spec, or the bearing went bad and the piston was freed from the crank then came up and slapped the head then on its way down the rod hit one of the lobes on the crank shaft and pushed it out the side of the block. It is a sad day <img src="/forums/images/graemlins/frown.gif" alt="" />
