Default 1998 Cabriolet 2.8 12v Oil Pressure Problems

Hi,

I have done all the searching and really have not found an answer.

My 1998 Cabby has 109k on it, no leaks, engine is very quiet, no smoke.

Recently the oil light has been coming on once the RPM's go above 2k.

These are the steps that I have taken so far.

1) Replace both oil pressure sensors. ( No change )

2) Replace cluster ( No Change )

3) High pressure engine flush ( No sludge and No change )

4 Removed rear pressure sensor and installed mechanical gauge.

My new mechanical gauge reads the following:

Cold Start 60 PSI at Idle

Cold Cruise (2k) 80 PSI

After 30 minutes 15-20 PSI at Idle

After 30 minutes (2k) 50-60 PSI

After 30 minutes (5k) 60-70 PSI


Are these readings ok?

Thanks
Jason

It does seem quiet around here. Wish I could help with this. I have a weird problem where my 97 Cabrio will inexplicably have the oil disappear without a reason that I can see. No smoke, no leaks. Unless the cat is burning it up without me seeing it at the tailpipe?

readings are fine, does the car drive fine? as long as you know there is enough oil in the car, no leaks and consumption hasnt changed i think you can chalk this one up to an electrical fault.
