Sure sounds like stopped up return passageways, common in old engines. Or a failing oil pump, not common. Are you sure about this low mileage? Pull a valve cover and check for sludge.

If the car is having trouble maintaining idle (the tach dips and car dies) the common causes are the idle control valve and camshaft position sensors. The cam sensors failing will be indicated by a check engine light.

The ICV can removed and cleaned with good results (I think there is a write up on bimmerfest) or purchased new for about $100.

While you are in there check the intake boot that is Y shaped for cracks, it's prone to fail and will mess up your idle too.

SOURCE: 89 Ranger 2.9L 150k mi. Lifter noise, power lose, oil pres zero

the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.

1990 5.8, 74000 miles well maintained. Oil preasure drops off


Why are you running 10 - 40 weight oil. You might want to rethink this. As the miles go up the ware on parts goes up. So I would recommend a 5 - 20 or 5 - 30 high mileage oil. If the oil pump is that new and working properly then this will help with the pressure.

Loss of oil pressure


How many miles are on the motor? Are you using the correct weight oil?

As oil warms, it gets thinner, and the pressure will drop as a result. When you say the pressure comes back after re-starting, is that after the vehicle has been sitting long enough for the oil to cool down, or does the pressure come back if you shut down and immediately restart?

I have a 1998 Jeep Cherokee with a 4.0L engine. The oil pressure gauge usually stays around 40 on the highway but when I come to a stop it drops down to 10. Is this normal or is my oil pump getting ready...


No this is normal. As an engine wears then oil preasure will be less this is not due to a weak oil pump but wear in crank shaft bearing's. When an engine is new and bearings are tight then oil preasure wont fall a lot from reved up to idle as the engine wear's oil escapes quicker from the crank shaft bearings. Reved up oil preasure increases idle it drops off. If the oil light stays out then their is enough preasure to lubricate the engine. In fact in an older engine high oil preasure is a worse complaint as this means the oil system is clogging. All is ok with your pump. If the oil preasure is moving up and down at constant rev.'s then the oil pump is faulty. Hope this put's your mind to rest.

My 2000 Jimmy won't start, I can hear the fuel pump running and then shutting off before I attempt to start the engine. I also hear it running while I attemp to start the engine. The engine won't start...


The pump is working normally the reason it stops before you start the engine is it has built up enough preasure and cuts out. When you turn over the engine it starts up again as the preasure goes down when the carburator open's. The pump only helps the fuel from the tank. It seem's like dirt in your carburator. The reason it wont start after 3 minutes is the excess petrol in the carburator has evaporated hence need to pour more in. Check all pipes filters and carburator for dirt.

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!

Car stalls when oil pressure drops...20 minutes to restart


No it is a fail safe. When your oil pressure drops below (on most cars) 30 psi your computer will shut your fuel pump down until you either let it sit for a while and it resets or until oil pressure builds again. Sorry!
