Hi Lee, There are two oil pressure relief valves on most vehicles. One is fitted onto the oil pump assembly and another onto the oil filter housing assembly. The oil pump pressure relief valve is located at the front of the engine and is accessed via a blind nut on the side of the unit. The bolt is in the form of a cap, which when removed can be seen to be holding down under tension a spring, which in turn presses the valve. If the pressure becomes too high the valve body is pushed upwards and releases an amount of oil, thereby maintaining the required pressure. The valve built into the oil filter housing works in much the same way, but its job is to allow oil circulation in the event of a blocked oil filter. regards John

the oil pressure switch is on pssenger side, lower engine area,beside oil filter, mounted in engine block. The pressure relief valve is in the oil pump, in which case, you have to drop the oil pan,and take off the oil pump.

I'd suggest using a good brand of synthetic oil (which was actually developed a really long time ago for the armed forces for use in polar reigions) Most flushes loosen too much material all at once, causing blockage of the oil pickup screen. You can get a bit more cleaning and lubrication protection by adding a bit of marvel oil to the synthetic. Change just the filter (and lost oil) about every 1500 miles, till the problem subsides.

I don't believe there is a oil pressure relief valve, but there is a pressure bypass located in the neck of the oi filter mount. I would check to make sure that you have the correct oil filter on the motor.

What causes high oil pressure reading 1990 toyota pickup?


Probably a faulty oil pressure relief valve.

If not done already, you should have an independent oil pressure gauge hooked up to the lube system by a mechanic to check that the high oil pressure reading you are getting is correct. Before doing this change the engine oil and the oil filter and ensure you use the correct oil and only fit a quality and correct spec oil filter.

Oil presure guage jumps from 30 to 60 whats the normal operating range


Oil pressure should be around 30 at idle and then sit at 60 when engine is above 2,000 RPM. If pressure varies at all engine speeds it indicates a sticking pressure relief valve which is located within the oil pump. You could try using some oil flushing product in the engine oil before the next oil change to see if it removes the gunk that is causing the valve to stick. If that does not improve it you should see a mechanic about replacing the relief valve.

Sounds like the oil presure relief valve is stuck closed. I do believe the valve is built into the pump but I would ask when buying a pump.

Jetta 1990 digifant II no oil pressure at all not even a smidge checked with manual oil guage to the head. wouldnt a bad pump still pump. what about pressure relief valve?


Sounds to me like your looking for a new motor . If the pump is so bad as to have no pressure it either has high mileage or broken internal parts jamming it. A non-working pressure relief valve is almost always the result of crud build up, also not good. If that valve is full of crud chances are pretty good so is the rest of the motor resulting in poor circulation and excessive wear. You may get lucky when you open up the motor and find something simple like a sheared pin at the oil pump drive but I wouldn't count on it unless this is a sudden problem and you had good pressure all along.

1998 FORD 4WD RANGER 128,000 MILES ENGINE LOST OIL PRESSURE OIL PUMP LOOKS GOOD NO SLUG IN OIL PAN, WHY?


Most likely your oil pressure relief valve located on in or nearby pump. Symptoms are oil pressure will drop when warmed up when idle lose all pressure eraticly giving the vehicle gas will bring back pressure and highway driving will bring pressure up until idle again.
