STOCK OIL PRESSURE

On a stock turbo buick it is not uncommon for oil pressure to be as low as 10-20 psi hot, I have seen a few get lower than 10psi at a idle hot, with no signs of internal problems.

Have you driving car for any length of time at all.

 

[87grandnat]

no i actually havent driven it in a week and a half so i guess that could have affected it, but thats a big difference between 10-20 and 60 that kinda concerns me

If you have not driving the car anywhere since you put a oil pressure on it, i would recommend doing that first. Then see what happens then, we have had cars that we let run for a while at our shop & they appeared to have higher than normal oil pressure until we had driven them for a while. Let us know if that makes a difference. If not feel free to contact us at www.aggressiveauto.com or (586)771-9122

well i let it run for a while and it dropped to about 39psi i guess it would drop down lower, i just didnt wanna let it run to long becuase my fan doesnt work so i dont want it to over heat, and i really appreciate the help your giving me

No problem! it sounds like you just need to drive it for a while, when you fix your cooling issues. Good luck

I've had em run as little as 15psi and another that ran as much as 80psi.. My opinion, nothing wrong with 50-60.. I'd feel more comfortable with that than 10-15psi..
