A friend had similar carnage to his motor, It was determined that the spiro lock came out, [ it was found to be in good condition ] the pin slid out causing the rod to break off the bottom of one side of the piston,then the rod proceeded to poke around for a while with nothing but a rist pin on the ending up with a similar picture like yours. Sorry, i hope mine don't come out.
it's ok to butt heads, just don't do it with a butthead
