oil pessure acting weird what could it be only 57k running mobile 5-30

 

What exactly is it doing?

 

What do you mean, it's running wierd? Is the guage spikiking or what? Have you checked your oil levels? Notice any drips?

 

What do you mean "acting weird"? is it bouncing around? Maybe its the gauge/sender/wiring?

 

Is it a mexican jumping bean!?

 

As long as its not ridiculously low and moves up with the rpm's you're fine.

Especially if it only "acts weird" when the car is hot. Thats because the oil thins out when the temp rises.

 

well at idle it it is very spuratic is reads great at cruise and wot but its just at idle . sorry i was not so clear on problems.

 

Spuratic pressue at idle can indicate worn bearings. But there's other things to check before you go pulling things apart.

If you feel there really might be a problem, hook up a mechanical guage and verify the pressure. This will eliminate the guage, wiring and sending unit as suspects.

From there if it's still a problem, you can go on checking the oil pump, bearings, etc.

How many miles? The guages aren't so acurate, I'd be willing to bet there's not much of a problem. GM sped says you should have 10psi for every 1000 rpm.

Good luck!
