I try to search before posting this question, but I was not able to find a good answer sorry


but the question is I just installed a type r oil pump in the car and the idle at 754 RPM when the car is warm the pressure is around 12 to 16 PSI, when the car goes up to 3000 RPM the pressure is around 45 to 50, also why is with this pump sometimes in the morning when the car is getting ready to start the oil pressure might jump to 80 or 85 PSI is this normal?

I got crank damages before for this issue and I just need to make sure that everything seems ok

 

what type of gauge are you using to measure oil pressure?

 

I try 2 just to make sure but both are autometer

 

idle pressure is ok, but at 3k it should be more like 70, yours is low.
when you first start the car pressure reads high because of the thicker viscosity of the oil being cold.

 

low oil pressure = rod bearings. Not always, but most of the time. You mentioned you had crank damage....
