'91 Camaro - low oil pressure

[riffwraith]

Hi there - I have a 91 Camaro with a 305 and 119,000 miles.

My oil pressure has been low the klast few days. The first thing I did was check the level which is fine. I have no means of checking it any other way; I have no gauges, and am not very mechanically inclined.

Typically, when I start the car, the psi is @ 60 - now it is at 30. And it slowly decreases to about 15 as the engine works up to operating temp. It will stay at 15, and flooring the gas on an open road does not bring the pressure up - which it used to. Otherwise, everything is fine - no wierd noises, no sputtering, no stalling, nothing. The only odd thing is that when I turn the air on, the oil pressure gauge spikes down into into the red, and then snaps back up when I hit the gas.

Is this indicative of a bad fuel pump, or possily something else?

Thanks in advance for any ideas.

My guess would be that the bearings are worn out or the oil you are using has too many miles on it or the engine is overheating and using the oil to cool the motor.

Take it to a mechanic and have him find out if it is a bad oil sensor or a bad engine.

How many miles are on the oil and what manufacturer and grade of oil do you have in your engine?

These cars are famous for Oil Pressure sending units going bad ($20 part) that bolts into the bottom driver side of your block, change that first and you might be surprised!

Good Luck.
