Are you certain it is the oil pump? Have you checked the actual oil pressure with a guage? There are other things that could cause low oil pressure, such as the pressure relief valve. I would get a manual on the car. This should tell you all you all you need to know, including how to change the oil pump, if that is indeed necessary. I'm not certain if you can pull the pan on that car without pulling the engine. Some you can, but you have to support the engine while you remove the cross member. Again, a book will show you the easiest way. I hope I have been helpful.
Yeah either one...but that doesn't cause the low oil pressure light to come on. When you have oil pressure light comes on, that means that your oil pump is failing and/or your main bearing seals are failing. Costly repair.
May be low oil, low oil pressure (faulty oil pump) or a bad pressure switch. When your at highway speeds the pump, pumps faster & brings the oil to the right PSI. Try a thicker oil than called for, get the oil pressure checked,oil leaks? & get the switch ckd out.
Low oil pressure is caused by bad bearings, low oil level. faulty oil filter, pump pressure regulator faulty and wrong grade of oil .AS to the other run the fault codes to check for faulty sensors.( probably MAF sensor )
LOW OIL PRESSURE WILL CAUSE OIL PRESSURE SWITCH OR SENDING UNIT TO DISABLE FUEL PUMP.CHECK FOR OIL PRESSURE.REMOVE OIL PRESSURE SENDING UNIT SCREW IN OIL PRESSURE GAUGE TESTER INTO BLOCK WHERE OIL PRESSURE SENDING UNIT GOES TURN ENGINE OVER CHECK FOR OIL PRESSURE SHOULD BE 18 PSI @ 2000 RPM. BESURE TO WRAP TEFLON PLUMBERS TAPE AROUND THREADS TO THE OIL GAUGE PRESSURE TESTER OIL WILL SPRAY EVERY WHERE.IF YOU ARE GETTING NO OIL PRESSURE.YOUR OIL PUMP FAULTY.YOUR ENGINE CRANKSHAFT BEARINGS WORN OUT.WORN DAMAGED CAMSHAFT OIL PUMP DRIVE GEAR OR OIL PUMP DRIVE ROD DAMAGED OR BROKEN. IF OIL PRESSURE OKAY OIL PRESSURE SENDING UNIT IS BAD.
The oil light is signaling low oil pressure in the engine's lubrication system. You say that you have checked the oil level in the engine and it is ok.
The oil pressure needs to be checked with an oil pressure gauge. (It is most unlikely that the warning light is faulty).
Should the oil pressure prove to be low - as I expect it will - the cause needs to be investigated. It is likely that there is a malfunctioning or failed oil pump or the oil pressure relief valve is sticking in the fully open position.
Failure to change the engine oil, at least at intervals stated by the manufacturer, will result in severe oil degradation and reduced oil pressure. However this is usually not enough to trigger an oil pressure warning light. If you have changed the engine oil in the last six months or so, and have not done over about 7000 miles since then, oil degradation should not be contributing to the low pressure problem.
If the oil pressure gauge check confirms low oil pressure I suspect, on further investigation, that you will find a problem with the engine's oil pump.
You will need to get your vehicle to a reputable auto service shop to have the oil pressure checked and the problem investigated. Do not drive the car in this condition (except to get it to the repairer). The engine is not receiving sufficient lubrication and you run the risk of expensive engine damage and total engine failure.
I have a 94 4.0L and I use 10W-40 in the winter and 20W-50 in the summer. It keeps the pressure up and it doesn't smoke when I start it because of the valve seals. It takes 8 quarts everytime including the filter. 2 gallon jugs. I change it about every 4,000 miles.
