Low Pressur Light Off and On

97 Aurora 135,000 miles

When car is first started PSI reads in the 70s or 80s..after 15 minutes of drive time pressure begins to drop to 0 when in idle position. As soon as it is given gas pressure rises only to drop again when coming to a stop. Checked oil and it is okay. Doesn't need any added. Had oil changed and stabalizer added, also had new filter put in. Also had spark plugs replaced. Problem with oil pressure light and loud beep (warning sound) still there.

I am as dumb as a box of rocks when it comes to automibles, only know how to pump gas and fill low tires with air.

Your help is needed.

Thanks

It sounds like you may have a clogged oil pressure relieve valve. Take a look at the response to this post.

The first step is to make sure that that your harmonic balancer bolt isn't loose. But if its tight, the the post outlines a procedure for clearing out the relief valve by adding 10-12 quarts of oil to the engine, revving it and then draining and refilling. If it sounds crazy to you that is normal, because it is crazy...crazy enough that it just might work...

Actually, I've seen other posts were people successfully did this and it fixed their problem.

Good luck
