I changed out the oilpan and the oilpump today, I was opening to get better idle oil pressure, it was 10 to 12 PSI when the motor was up to temp. I wanted a better oilpan anyway. So I put in a high volume, high pressure oilpump and a 7 QT pan. Now I have 18 to 20 PSI at idle. What is the right pressure for idle, I do alot of my wheeling at or just at idle not at 3 to 4k likr some do. By the way at 1k its 25psi,2k its 38psi, 3k its 48psi, at 4k its 60 psi. So it seems right the rest of the time.
