Ive fitted a mechanical oil pressure gauge, so the oil physically travels up a nylon tube to give the reading, its been put in place of the original sender. I started the car today, but the pressure seems to fluctuate, a few psi, is this morning, or should i of some how bled up the oil system or somthing. ? ,
Also to add, what kind of oil pressure (psi) should i be looking at to make sure my oil pump is functioning properly, before i put my new turbo on.
