Here is my latest.Like a moron I forgot to tighten exhaust cam caps after doing cam timing.Got maybe 15min off this motor.Oops![attachment=8405:Cam_Cap_Loose.jpg]
Yep, that is how it was when I tore it down. I don't think the crank sheared the wristpin as the piston was still at the bottom of the stroke.
If that happened I would think the piston would have been smashed into the head which it was not. There are no MAJOR gashes in the sleeve which leads me to believe that when the wristpin hit the wall it sheared the rod and it continued its downward stroke smashing out the bottom of the case and putting a massive dent in the engine cradle. Probably the "BEST" case scenario really instead of trashing the head as well
