Yes it could be your oil pump but also can be your oil pressure sensor, or if you havent changed oil in to long of a period

I suggest you pass this one by - the oil pump probably is shot and you'll get a hefty repair bill on top of the purchase price!

I had the same problem and ended up changing the oil pump and it did not fix it. (Peace of mind anyway and it was cheap) I replaced the pressure sensor (that happens to be tucked in deep between the back of the engine and firewall) and the pressure gauge worked just fine after that.

SOURCE: difference between oil sending unit and the oil pressure switch

Same part...make sure you get one for gauge, not idiot light though. If the engine has any knocking or ticking when pressure drops do not drive it and have a mechanical gauge installed to check actual pressure. Parts often have different names for same item...your driveshaft is actually called a propeller shaft!!!

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.

Your oil pump is failing.... when your engine rpm drops (when stopping) the pump and engine rpm drop to idle..(light comes on). when you accelerate (rpm's increase) the pumps start working harder and the light goes off.... I am TRULY surprised the dealer(who did you see at the dealer???) did not know this,... THIS IS BASIC STUFF!! ... I mean 090 level mechanics...

Oil guage drops to near 0 and the check guages light comes on when I am at idle or on a slope at idle. Is this a concern, or dont worry about it


It means that your engine is loosing oil pressure, it is a concern to be worried about. Check your engine oil level, the engine might need oil.

Hi:
Usually your oil light doesnt come on unless you have less than 10 lbs of oil pressure. You either have a bad oil pressure sending unit, or your engines oil pump is bad. The only way to verify your engines oil pressure is to buy a direct reading pressure guage and install it on your truck, or have a mechanic check your engine oil pressure. Eitherway, you need to do something soon, because the long term effects of running with low oil pressure will ruin your truck engine.

"1997 e250 oil gauge flickering and oil light comes on and off Now the engne has a ticking sound"


You are losing oil pressure! Don't run the engine without the proper repairs!!
Check the oil level, if it's in the safe range, then it's possible that the oil pump is not working(this is a major deal, and could be a sign of other problems...if there's something plugging up the screen on the pickup tube, it could mean that something's coming apart inside the motor. I would drain the oil, and run it through a strainer to check for metal or plastic particles in the oil that could be from pistons, rings, timing gears... but dont' continue to run your engine without the proper oil pressure! the guage flickering means that it's dropping to unsafe pressure! a solid light means you've lost oil pressure.

... If there's no oil on the dipstick, add oil 1 quart.. and then recheck... add more as needed, but don't overfill.
