oil pump problems!!
ha sanyone seen a oil pump(M55) break off? It broke by the dail pin holes, the pump, screen, and oil pump rod was in the bottom of oil pan when I pulled it off. the top part of the oil pump was still attached to the block. It never made any noise, just noticed I had no oil pressure, and turned the engine off.Just wanting to know if anyone has had this happen or maybe what caused it. what it be good to go with a M55hv?
