i have a 1994 ford mustang with a 3.8 v6. Recently, the oil pressure in the car dropped to completely nothing. When i looked at it, the O-ring on the oil filter blew out every time i started the car, and all of the oil would pump out in a matter of seconds. The oil pump seems to be fine, and i was told by a mechanic to check the OIL PRESSURE RELIEF VALVE.
WHERE EXACTLY IS THIS RELIEF VALVE AND AM I CHECKING THE CORRECT THING FOR MY PROBLEM?
Any kind of input would be very appreciated!
