[QUOTE="BLACKJKU, post: 434778, member: 18221"] I'll have to say i've never seen anything like that on these engines but usually when something like that happens it's because a timing belt or chain broke. But if you say it was still running then it didn't break. Does the rocker arm still move freely? Maybe try pushing the valve down to see if it's stuck. Do you have one of those cameras you could pull the sparkplugs and look inside the cylinders? [/QUOTE]
