i recently installed my oil pressure gauge. the needle seems to slighty move up and down during idle. is this normal? its the defi d. thanks

 

i would like to see the answer to this myself. Also what are the proper reading for this gauge on average.

 

i guess no one has a oil pressure gauge.

 

How much variation are we talking when you say up and down? FWIW, on my old hybrid civic hatch that I built, oil pressure once warm at idle was 25psi and climed to 75psi once at WOT, there was a check valve at 75psi and peak oil pressure remained the same from 4k rpms to redline or something of the sort.

 

it will flucuate, but no more than a couple pounds.. same as you will have more pressure when the car is cold than hot..

 

it only fluctuate by a few pounds

 

That's normal. Keep in mind any loading like electric fan or power steering pump will affect the rpm a bit, then transfer to little up and down on oil pressure.
