The biggest pieces will probably stay in the crankcase .Fine metal will be caught by the filter and/or mag drain plug. There is a screen on the pump intake BUT small pices could be pulled up by the pump It only takes a small piece to jam the pump. If that happens the pump driveshaft snaps and the pump stops. If the engine is old enough to have the round metal inspection plate on the bottom I would pull it next and look for more big pieces. Cut open the filter. If there aren,t any you can cross your fingers ,do a couple oil changes . I,d probably dismantle it. Especially if you still have an unexplained noise after replacing the obvious damage . If you dismantle get the oil coolers sonic cleaned.
