oil gauge erratic...still

oil gauge was doing this for a little while. It has stopped but it will occur every once in a while randomly. What might this mean? I do have a oil leak and Im working on tracking that down once i get all the oil spray cleaned off the underside of the engine.

Moving on from the brakes to the oil pressure guage....

You could have a faulty oil pressure sender. It is attached to the oil cooler.

First clean the contacts on the sender. Be careful-, the posts are hollow and brittle. Very easy to break off. Locally a sender can cost $50 or more.

Check the wire to the sender. It lays over the top of the WP water pump and the sheilding gets brittle and cracks. It may be shorting on the engine block.

Replacing the sender may solve the problem.

Another possibility would be the "O" rings on the OPRV oil pressure relive valve. If they are hard and brittle it would cause a fluctuation on the dash guage. Order the "O" rings and replace. No alignment tool is needed if you do not move the OPRV housing. Get the aluminum crush washers for the OPRV and the drain nut at the same time.

Mine did that when one of the wires at the sender was loose.

@ John_AZ I'm sure the order of repairs doesn't make much sense, but at least now with a operational clutch and brakes I can atleast limp her to a mechanic if need be.

Be careful what you whisper about your car.

It may seen unusual but "bad news happens in threes" I have been told.

Mine did that one day after I put in a new Alpine CD/MP3-Deck I pulled out the center console again and checked the wires going in the back and that 2 wire plug-in was just vibrating on the tongs and plug connector making my gauge act just like that.

This is with it working now with me turning one the car and off again to show you how fast that needle can jump. Hope this helps.
I posted a video response on Youtube but it says I have to wait for you to okay it!
