Your oil pressure is valved either at the oil pump or oil filter housing. Valve may be stuck open. Outside chance oil pump drive shaft is broken from the pump sucking up something it should not have.

joemom you must have mis-worded your answer. I have a lot of respect for your posts. But maybe re-phrase that....? If the oil pump was not working...failed... the the engine would be destroyed in a minute, You know that my friend.
