after some searching, i really didn't find the answer i was looking for.

recently swapped a jdm h22 into my civic.

i have the autometer 0-100psi mechanical oil pressure gauge.

when i first start up the car, oil pressure is at around 80psi at idle (1500rpm). now sometimes, its goes to 100psi or MORE.

when the car is warmed up and at idle, the pressure varies anywhere from 0psi to 30psi.

sometimes while driving, the gauge jumps very fast, like a vibration ya know?

its odd. i don't know if its the gauge, or something seriously fucked with my motor.

thanks in advance.
