Is this oil pressure ok? at idle (1000 RPM) Oil pressure sits at about 30 and at 5000 rpm it sits at about 60.
It seemed to be a little higher last year before i did my head/cam install.
When i first start my car cold idle pressure seems to be about 42 or so but as it warms up it drops to 30-35
At 2000 rpm it sits at or a little about 40 psi
Am i good to go or is that too low

Re: Is this oil pressure ok? i think the target oil pressure is somthing like 10 psi for every 100o rpms
However im just concerned because it seems a little low to me.
Any other comments

Re: Is this oil pressure ok? at idle when mine is warm my oil is aorund 25-30

Re: Is this oil pressure ok? Before Cam After Cam(new
oil pressure
sending unit)
Idle cold(1050rpm) 45psi 39-42psi
Idle warm (850rpm) 38psi 25psi
Warm 5000(rpm) 55+psi 55+psi
I did brake my pressure sending unit and replaced it with a new one once I had to pull the head to retrieve and place my dropped lifter.

My oil pressure is in the 50s idling cold, but drops to the low 30s idling hot. If I just did alot of WOT and the oil is really hot, then it drops to ~26psi. Driving at 2000rpms it's in the high 40s for me. My oil pump is stock but the relief valve was shimmed for higher pressure.

Warm idle after a good beating or on a really hot day after driving a while: 30psi
WOT: 55-60psi
My oil pressure with a ARE ported pump and a 800 rpm (both park & in gear) idle, 10W30 syn oil:
Cold start: 60psi
Warm idle: 45psi
Warm idle after a good beating or on a really hot day after driving a while: 40psi
