ok, just finished my turbo, and I have 4 qts in it right now. When I start it, it reads fine, like 75, but as it warms up, it drops down to like 50 at idle, then after a few more mins it drops to 25 at idle, what could be wrong? No oil leaks that I can see and oil is fine.

 

Thats fine. Mine idles at about 25 and at high RPM is at about 85+. Its not a problem.

 

cool

 

remember the oil pump work off engine speed (RPM) , the higher the RPM, the higher the oil pressure.

everything sound ok fine

 

Exactly... I learned that at the track last week. I would throw my car into neutral after I crossed the finish line and my buddy's like, what the ---- are you doing? Your turbo is spinning at insane speeds and you're cutting the oil pressure...
