I have a 2002 dodge durango 5.9 4×4 that’s doing the exact same thing…I’d like to know for sure if this is a oil pump issue..only thing is..I heard a metal grinding noise at the back of the oil pan and a whirring or whinning noise.

In reply to David Owenga. Thanks for the feedback. The oil pump is like the engine's "heart" that pumps oil around it.

Insightful article, I love reading it. My opinion though, the introductory paragraph talks of functions of engine not oil pump.

I have a Hyundai Elantra 2005, it was making noise from camshaft side when the valve cover was opened, it was seen that the timing has jumped by one chain link and the was slack, the adjuster wasn’t strong either. The chain, adjuster, chain guide and the inlet cvvt gear was changed. Everything was fine as the car was first started but when the engine warmed up the noise started spontaneously and when the timing was checked it was still okay but the chain was still slack. Could that be oil pump not powerful enough to enhance the adjuster. Pls, I need your expertise advice. Thanks.

In reply to MICHAEL ZAJAC. Most oil pumps are driven by the crankshaft, which means oil pressure increases as engine speed increases. If oil pressure appears low at low RPM, there could be a restriction that is overcome at higher pressure. The best way to tell if your oil pressure is actually low is to do an oil pressure test with an external gauge. The factory manual should have a specification for how much oil pressure the engine needs at idle. If you can't find the spec there, check the Durango forums.

Hello
I’ve got an 09 Durango, that the oil light comes on at low rpm, it goes back to normal with a little gas, I’ve changed the oil sensor, it stop for a bit but now has come back, lots of power in the engine, and no noticeable change in water temp. Is the pump failing or could the pick up is dirty. Just wondering what you thought.

In reply to obert ubisi. I would get that oil light diagnosed. It is possible the cause of the oil light was not the oil pump. You may want to run an oil pressure test to make sure you are getting adequate oil pressure. If you are, I would suspect the oil pump is OK.

hi guy
I replaced an oil pump three month ago because of the oil light was displaying on the dashboard , within three month there’s noise of lifters and I have been told to buy oil pump again because the oil light didn’t disappear. is it right to buy oil pump or he must check the lifters.

In reply to autotechnician. If you have a 1990 k1500 idk how many miles are on it but they are known to be high clearance motors. I bumped up to a 15/40 weight oil on mine years ago on the advice of an awesome old school mechanic. We knew the drivetrain was in great condition otherwise. Great advice, the truck is still running strong with over 350k miles on it, and it’s been at least 150k since I switched to the heavier weight oil.

In reply to Luma. I have a 2009 chevy silverado 1500 with the 5.3 my oil pressure usually stays around 40 or 50 psi I just got through with taking the motor down to the block for a 3rd time for number cylinder lifter collapsing now that I have it all back together took it for a test drive during test drive notice if I wasn't accelerating my oil pressure would keep getting lower and lower till it dropped completely code says oil pressure switch replaced it still doing g same thing any suggestions
