Oil pressure question
k i put a piller on my legacy and attached a oil pressure gauge and its reading at 75 PSI at 3k rpm and about 15 at idle is too much bad or is that normal?
the reason i put it in was because my engine light never came on when i lost my oil drain plug hehe

Ive been looking for this spec aswell. I believe from what i found in the 92 FSM is ~22psi at idle and ~45psi @5k rpm is what is says for the turbo.
Did you use a mechanical or electrical? Im looking at getting an electrical aswell just to monitor such an important thing. Any suggestions on a cheaper one? Also what can be done about the pressure sender light with a new electronic sensor? Do they output a 12v source when there is pressure or am i going to have to rig something up

93 SS 143000 miles new oil pump
running autometer electric sender.
when warm ( 210-240 degrees in the oil)
the car runs about 75 psi at 2800+
at idle, it sits at about 20-22 psi
My Nissan Maxima runs about the same PSi at idle, but does not get near as high at 3000 rpms
if you go below 17psi at hot idle, I would start to worry.

Yes I have too many Subarus
No you can't have one

As I recall, on the turbos the oil jets open to squirt the "underside " of the pistons at 57 psi .

on a cold start... it's around 80psi
after warmup... around 15psi at idle
highway cruising is arount 20'ish
pressure goes up during acceleration
usually around 50psi
autometer gauge, electric sender.
pressure sensor hooked up to the block where the stock low oil light sender used to be.

From the FSM:
14psi @ 600rpm
43psi @ 5000rpm
Pressure relief valve:
85psi Turbo
71psi N/A
Warmed up, mine runs about 15psi at idle and 55-65psi above 2500rpm (depends on ambient temp and how hard i'm workin it). Gauge: VDO electric. Oil: Castrol GTX 10-30, pressures run slightly higher fresh, slightly lower when its due for a change.

No matter how broke I am... I always seem to find two cents.

The rally car runs at about 75psi at 3000ish and drops to 55psi at the same rpm after a good stage trashing in CA hot sun. At idle it's about 20psi . I always use a mechanical oil gauge. I use the oil pressure as a good yard stick to see how the engine is. After Laughlin last year the pressure cold at 3000 had dropped by 20psi hence my engine rebuild. Oil is Mobil 1 15/50 cuz the engine had done 250,000. I plan to use a lighter oil after the rebuild , but may still use 15/50.
Cheers
