Question about 2001 Nissan Altima

1 Answer

Our 93 cavalier with a 3.1 has lost oil pressure and there is a ticking in the engine. My wife told me the pressure guage had been dropping to 0 but would jump back up where it was supposed to be fair

The car is a convertible and prior to this there have not been any serious mechanical issues. The oil is normally changed regularly however I have been medically unable to stay on top of it for the past ten months not realizing the oil was not checked on a regular basis. If I change the pump and it was due to not being full of oil, will it regain its power and quiet the ticking? It is our only source of transportation right now so I need to get this resolved. I don't want to spend money on just a hunch and would like to get some feedback from people who may have experience in this area. Is there anything I can do to check the pump prior to changing it or could it be something else? Thank you for looking over my problem and helping in any way you can.

First things first, change the oil & filter & run the car to see if the tic & noise stops . i see this alot people just forget or like you have issues that take thier mind of off the normal maintenance off the vehicle. the oil change should help and you have to drain the oil to see if there is any metal in it!! give that a try & dont use any additives until you have changed it . wayne

SOURCE: Engine ticking

You didn't mention anything about the push rod.If you haven't already done so, take the push rod out and look thru the hole and see if there is any build up of sludge, and run a piece of wire down thru it, or replace it.Might be warn just enough to cause this, or warn cam lobe.Hope this helps, you have done everything else.

SOURCE: Engine ticking noise on cold starts

Sounds like a stuck valve lifter. I'd use some oil additive for unsticking lifters.

It may be just an issue with the car's electrical components. A low fuel pressure may cause loss of power when running. Check first the battery votage. It should be at 12.7 when the engine is off. If you do not have any voltmeter try jump starting the car using jumper cable connecting to another car. If it starts up quickly there is a chance that the battery is below12.7v or is weakening or the terminals may be just bad. If the same issue occurs then you may be looking at a weakening starter or bad starter relay. Check first for loose connection or wires in you wiring. It may just be a loose ground wire.
You can directly connect the starter to the battery to test the actual motor. If the starter motor is good directly connected to the battery to test. If it runs OK then it may just be the relay. Or have the relay tested first. You can have it swapped with a known working relay from another car. If it works then it may be the starter motor.

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.

Highly doubtful that a pump will fix a 0 oil pressure problem. This sounds more like worn bearings. Have a shop do a pressurized oil leakdown test before replacing the oil pump. If the bearings pass the test, then try a pump.

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 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.

1989 F150 351 oil pressure guage starting dropping to 0 suddenly and engine light comes one. When I rev the engine it goes back to normal but a soon as the rpms drop the needle goes all the way to the left...

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.

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!!!

The oil pressure gauge keeps dropping down to 0 while i am driving

If you don't hear any ticking or knocking while the pressure gauge drops, the problem is probably a failing "oil pressure sensor". If you do hear a ticking or knocking, the problem is probably a failing "oil pump".
