I'm changing the oil pump in my nephews 91 5.0 because of low oil pressure(I know it could be a bad bearing I'm trying this first with motor still in car). When I removed the pump and pick up I noticed chunks of black plastic wedged in the screen and all in the oil pan. At first I thought it was metal but its not magnetic and I can brake it in peices with my fingers. Anyone know wha this is?
