Question about 2000 Ford Expedition
My oil pressure take jumping up and down and my truck is making a weird sound wat can that be
Posted on Mar 04, 2013
Are you sure no oil is circulating? If your oil gauge shows no pressure it could be the gauge or sending unit that isn't working. If no oil is circulating your engine will probably not start, since the valve lifters operate on oil pressure. If it does start it will make a lot of noise as the valves and lifters slam against the cam shaft. The oil pump works directly off of gears built into the engine. It is possible to shear the brass gear off the pump. This doesn't happen very often. Another possiblity is that the screen in the oil sump tank is completly stopped up and thus prevented the oil pump from sucking up the oil.
