Oil pressure drops to 0 then goes back up


Definitely needs resolving.
Since both light and guage drop occur, problem would appear to be with oil pump or oil delivery rather than simply a bad guage.
You could check to see if there is a common sender that may be defective.
It is also possible that the oil pump pickup screen has an obstruction.
I'd be looking at the recent history.
Has ANYTHING been done to the vehicle that might lead to this problem
Make, model, milage, maintenance history..........
All will help to track down the problem.

While driving my chev 454 truck the oil pressure went to 0 psi


A leaking filter and oil pressure switch would cause the lack of oil pressure. Does the oil light work and does it go out now you have changed these parts. It only needs approx 8 psi to put the light out, the engine should run at approx 40 psi at 2000 rpm.

Oil pressure guage stays at 40 psi on ign/engine shut down, but drops to 0 psi when ign is turned back on, and then on starting of engine operates normally... What's up ???


the oil pressure gauge only gets a reading when the engine is runningas the oil is being curculated. when you shut the vehicle off it should go back to zero and be there until the vehicle cranks back up. i hope this helps

I got in my 2001 Expedition, started it up and the oil pressure light came on. The guage was down to 0. I stopped it and started it again. The guage press. went up and then slowly dropped at first and...


oil pump gears inside the lower engine, or electrical. 1st make sure its full on oil, then sheck it with another pressure guage to confirm its not actuall pressure.

Oil light flickers when in idle. Oil on dip stick measures fine.


install a mechanical guage to test the actual pressure, if its fine the sending unit is faulty, if nor remove the oil pan and check the oil pickup for blockage,

1996 chevy corsica,2.2 oil pressure DROP when hot????


dont run it anymore!!!
check oil is reaching the rockers & that there are no blocked feeed holes !
the pump may have been fitted too loose or the gaket is not sealing creating a pressure drop!
it may have some of the old bearing material enter the gallery,s & or the pump!
good luck Cheers Rob

OIL PRESSURE GUAGE, IT SHOULD BE STABLE?


bout the oil pressure gauge its normal to go up but not to high coz u might overheat, try checking the cylinderhead gasket if there is pressure coming out, replace the gasket if needed

Low oil psi after driving 25 miles


Have a shop verify the pressure is really low, it could just be the sending unit is defective for the oil press guage, but get it checked, if it really low you could burn out the bearing in your engine, a very costly repair.
