Ive done a search and everyones problem seems to be the same but my problem is just the opossite. I have an 88TII, rebuilt engine with aprox. 30k on it. Still have factory turbo though and factory oil pressure gauge. My problem started tonight when I noticed my pressure was at like 30psi @3500rpms. It is normally around 95 psi at that rpm. So I pulled over and checked my oil level and I had oil in the engine. So I preceded on with caution, at idle psi is @ about 30. I take off and go through the gears and psi rises with rpms till I level out at a constant speed. When I do this psi drops to almost 0(ZERO). However, if I let up on the gas and coast, the psi comes back up over 60psi. I did this tactic numerous times to see if the result was the same after I noticed it.

Why would the oil psi rise when I let up on the gas and sit a zero at 3000-3500rpms when it used to be at 95psi? And whiy is the oil psi at 30 at idle, just like normal? Also my g/f said the ehaust smelt like something was burning, but there was noticable smoke since it was dark out.

your oil pressure switch/sender might be grounded.

 

When the engine was rebuilt, was the oil pump replaced as well? Was your car really hot? What weight oil do you have? Try changing your oil to thicker weight.

 

Ignore the stock oil pressuer gauge - it's only good to tell you if you got oil pressure or not.

Get an aftermarket oil pressure gauge and tell us the real numbers...
