    This problem happens at all RPMs, all speeds and at idle.

How do you change the oil pump on a 1996 jeep grand cherokee limited 5.2 liter.The oil pressure drops almost down to zero when in idle normal operating temp range range. Need steps.


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?

Oil pressure gauge drops to zero when car slows down, sometimes will go up when rpm reaches 2800, otherwise stays at zero, when shut off and turned on again pressure would be normal


Hi assuming the oil filter has not become blocked, it sounds like the oil pump is not working properly. Of course it could be something more simple like a faulty gauge, sender or bad connection. But assuming again that the engine is suffering from oil starvation, I would get it checked quickly before you seize the engine completely. Good luck!

Well it could be the sending unit for the gauge.
But odds are the oil pump or engine bearings are worn out.
As the engine warms up, the metal spaces expand and the oil gets thinner. The oil pressure drops some under normal conditions, but not more than 10 or 15psi. Normal idle pressure with the engine warmed up is probably 25psi.
You could check oil pressure with a mechanical gauge to make sure its not the sending unit.
Once the oil pressure starts staying below 20psi for long periods you'll start hearing noises.

My check gauges light is on, oil hands goes over to zero, moves up, light goes off, when it drops back to zero, gauge light comes back on.


Well the warning light is supposed to come on if any of the gauges display a dangerous condition, such as no oil pressure.
You may have a faulty sending unit for the gauge, or a wiring problem, or the engine may actually be loosing oil pressure when the gauge drops.
You could replace the sending unit as a test, or have someone check the oil pressure with a mechanical gauge.

Where is the oil pressure sensor located on a 1996 murcury cougar


Look for the oil pressure sending unit on the block or the cylinder head on the V-6 or V-8 models. --- OIL PRESSURE TEST Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge (as opposed to relying on a factory installed dash-mounted gauge). A tachometer may also be needed, as some specifications may require running the engine at a specific rpm.
  1. With the engine cold, locate and remove the oil pressure sending unit.
  2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
  3. Start the engine and allow it to idle.
  4. Check the oil pressure reading when cold and record the number. You may need to run the engine at a specified rpm, so check the specifications.
  5. Run the engine until normal operating temperature is reached (upper radiator hose will feel warm).
  6. Check the oil pressure reading again with the engine hot and record the number. Turn the engine OFF.
  7. Compare your hot oil pressure reading to specification. If the reading is low, check the cold pressure reading against the chart. If the cold pressure is well above the specification, and the hot reading was lower than the specification, you may have the wrong viscosity oil in the engine. Change the oil, making sure to use the proper grade and quantity, then repeat the test. Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.

1999 Jeep Cherokee Sport 4.0L engine. Oil


I'm assuming the engine is still running and no engine noise has occured due to loss of oil pressure, and it is just the gauge that is not reading? If so, the oil pressure switch that is located on the camshaft sensor, could have a bad connection or the oil sensor will need to be replaced. The oil sensor is located on the left side of the engine and is mounting horizontally on the camshaft sensor housing.

Oil pressure dropping after about 2 hrs running time mainly during a stoplight


first up.Is the oil recently changed.2nd is it the right type..3rd.Oil pressure will drop down when the engine is idling.If, when you give the engine a rev and the pressure builds straight back up,there is not a problem.Its normal.Cold oil will always give a higher pressure than hot oil.Check these few things and I hope this helps

My oil pressure gage just drops to 0!!!


You need to replace the oil pressure sending unit, this is what tells your gauge what the pressure is. For future information if your oil pressure drops again and its a real failed oil pump within a few minutes you will internally damage the engine. I would get a new Oil Pressure Sending Unit. Let me know if you have any questions.... Thanks!

1996 oldsmobile aurora oil pressure sensor says low oil pressure my mechanic checked it out and replaced the oil pressure sensor and problem still exsists he tested the oil pressure recommended 20 PSI when...


The Aurora is a low pressure oil system. The only solution available at this time is to increase the oil weight. I went o straight 30W to solve the idle alarm issue. Some use 20W oil and that works too.
With 20W you will be at 80 to 90psi cold then drop to 20-30psi hot.
I first replaced the oil pressure gauge and it was worse. I put the original back in and it was better. Then went to 30W and all is fine.
Running it that way for a few years now.
