i did this on my bike, but mine was the electrode on the plug breaking off, jamming under the intake valve, breaking the head of the valve off which then jammed under the exhaust valve, which simultaneously broke the head off of the exhaust valve and jammed it sideways AND pushed the intake valve head through the piston. The piston had a hole in it almost perfectly shaped like a hershey kiss, haha
