actually it could be anything from a muffler that has blown form a backfire to a timing chain or rocker arm coming off due to a bent pushrod. Normally on a timing chain you replace the gears as well as chain and gaskets, new antifreeze etc. If there are plastic pieces in pan form chain/gear breakage then they have to be cleaned out.
