It sounds like you have some internal engine wear. What causes the pressure to drop when you are at a stop is the engine RPM drops. When the RPM drops the oil pump does not turn as fast, when the oil pump doesn't turn as fast there is less oil volume, when there is wear in the bearings and even in the pump itself there is more volume of area that needs oil than there is available causing there to be pressure loss. The only fix for this is to replace the worn parts either by rebuilding your current engine or replacing it with a good salvage or new engine.
Depends on what vehicle you have. Most pumps can be changed by dropping the oil pan. It may require raising the engine somewhat for the pan to clear the sump. Some vehicles have the oil pump run off the crankshaft on the side of the engine as well and are easier to access and change
I'd be checking to make sure that the oil pump was not the problem before I tried to replace it.
How many KM/miles on the engine?
Regular maintenance?
Burning oil?
Kelea, if you do not hear a lot of engine rattling noises then I would say your "Oil Pump" is OK and you need to replace the "OIL SENDING UNIT" which you can buy at Autozone. CAUTION: If you do hear a lot of rattling noises coming from your engine then I'd suggest having someone check the oil pressure. If the oil pressure is low then it could be all kinds of things that can cause low pressures. From engine bearings, to restrictions, to the oil pump itself. I would start with the oil sending unit first and see what your oil pressure looks like. If your oil pressure is good after replacing the sending unit then I'd consider never taking my vehicle back to the shop that told you it was the pump. Hope this helps and have awesome day.
the 2.3 and 3.1 engines need to drop oil pan.for the 3.3 engine you have to remove timing chain cover.you have to remove oil filter adapter the pressure regulator valve and the valve spring.then remove oil pump cover to oil pump screws remove cover remove oil pump gears.when installing another new oil pump lubricate the oil pump gears with clean engine oil pack the pump cavity with petroleum jelly.torque oil pan cover screws to 97 inch lbs which would be 11 ft lbs torque.oil filter adapter plate 24 ft lbs.
there are a few possible problems. starting with the least costly would be an oil pump needing to be replaced. if your oil pump isnt bad then its a large leak somewhere in your engine usually caused by bearing failure requiring an overhaul or replacement of the engine. you say the oil drops? to what pressure?
Inside your engine is an oil pump assembly which is mechanically operated to pump oil your through your engine while the vehicle is running. There is a pick up tube which extends from the pump to your oil pan and a screen which helps to keep large debris from entering your oil passage ways and engine components. If that screen is blocked you will have low oil pressure, if the pumps diaphragm is worn out you will need to replace your oil pump and this would cause your pressure to drop as well. I would also suggest having your oil pressure sending unit tested to make sure it's functioning first before doing any internal engine work. Hope this helps you and best of luck
drain oil and filter remove.
Drop oil pan under engine.
Un bolt oil pump and re install new pump fill new oil and filter and gasket , cap , start engine test for leaks shut down re check oil level.
Vitally
The oil pump is in the oil pan and needs to be dropped and being a 4WD you also need to drop the front axle pumpkin to remove the oil pan and replace all the gasket needed. Start with the easy and replace the oil pressure sending unit, it's on the back of the engine to the passenger side of the distributor. You can go to Auto Zone and pick up a new Oil sending unit, just make sure your get the right one, "Sending Unit" Looks the same are the oil pressure sensor but the unit reads the pressure, the other just signal a light to go on and off. It's an easy fix like replacing a spark plug.
