Oil Pressure gauge reading 0psi at idle..
So I have a Glowshift Oil Pressure gauge, it's not the nicest but it's an electronic gauge. I put the sender on the oil galley where the oil light plugs into. When cold it jumps up to around 60 psi and when it's hot, at idle it sits on 0 and if I blip the throttle it goes upto like 10psi. At 2k it sits around 20psi I beleive.
Is there any way I would be reading less than 1psi at idle or is this gauge just screwed? I have been driving my car with this hooked up for about a month, so I feel like if my OP was this low I would have destroyed the motor by now.
Thoughts?

Re: Oil Pressure gauge reading 0psi at idle..
I have been using Glowshift since 07 and think they are great for the low price and quality. And yes if in fact your oil was that low REALLY, your motor would seize. I have yet to install my pressure gauge but perhaps you could get the sandwich adapter as well. Never had a problem with the adapter I bought from them.
Hopefully the other fellows can chime in on this.

Hmm okay. I think I may just have a bad sender then.

Re: Oil Pressure gauge reading 0psi at idle..
they'll read kinda funky if the ground at the gauge has a potential difference to the ground at the sender.

Re: Oil Pressure gauge reading 0psi at idle..
They both use different grounds. I think I'll try and run them to them same location. Thanks for the tip!

Re: Oil Pressure gauge reading 0psi at idle..
Bringing this back to life.
I got a new gauge, Prosport electrical gauge. Hooked it up, and it reads 0 at Idle.... just like the Glowshift did.
I am running a braided line from the galley behind the alternator (dummy light) into the sender.
It's been like this for weeks, there is no WAY my engine would be running if my oil pressure is this low. Does anybody have any input? I might switch the reading location to the back of the block and see if anything changes..

Re: Oil Pressure gauge reading 0psi at idle..
I put the sender straight on the block. No changes. I put 15w30 with Lucas oil stabilizer. Idle Oil Pressure sits about 4psi/5psi.

Re: Oil Pressure gauge reading 0psi at idle..
So is the sender the same as used with the previous gauge? How about wiring? All new? Any serious knocking noises at idle?
A lot of the guides for wrx's have the sender going to the back of the block like you mentioned.

Re: Oil Pressure gauge reading 0psi at idle..
I have used two different electronic gauges, with 2 different senders. Plugged into the stock oil pressure light location.
The car drives normal, and pulls normal. No knocking, ever so far. Not at idle. Cold oil pressure is in the 60-70 range.
I'm going to drop my pan and check for a cracked pickup tube.

Re: Oil Pressure gauge reading 0psi at idle..
I would throw a mechanical gauge on just for verification. My electronic transducer was 5 psi off across the range from the mechanical unit.
I'm also trying to figure out low idle pressure....mine is 5-11 psi depending on oil temp.

Also how is your car behaving? Running normal?

Re: Oil Pressure gauge reading 0psi at idle..
I used a Matco mechanical gauge I borrowed from a friend.
Car has been running fine. The oil was a little too black when I changed it at 500 miles...but my motor is still pretty new.
No excessive metal on the drain plug, but still makes me nervous.
I swapped out oil pumps and pressure did not change at all. I am now stepping up to 11mm pump. I should know tomorrow how that changed pressure at idle and in other areas.
What pressure are you topping out at, at full RPMs?
Also, the oil pickup tube could be a place to look.

Do you think a bigger oil pump would help?

Re: Oil Pressure gauge reading 0psi at idle..
At least it's not 0 psi.
I just installed the 11mm on my car....it did not help max RPM pressure (in my case), but hot idle pressure looks 3-5 psi higher.
What are you seeing for pressure at 5-6K RPM?

Where did you get it and how much did it cost?

Re: Oil Pressure gauge reading 0psi at idle..
I got it from Subaru....08+ STi pump. It was $180. I think 135 from genuinesubaruparts.com but 30 for shipping.

Re: Oil Pressure gauge reading 0psi at idle..
Figured it out!!!! The pumps screws were backing out. Thread lock and it's all good.

The oil pump screws where backing out? Like your oil pump was coming off your motor? Massive oil leak?

The screws that are on the inside of the pump that hold the rotor were starting to come loose. I guess it's a common thing that people have reported before. I didn't think about checking until now because the pump is new. I tested the pump pressure.

WOW, Good thing you didnt just accept that your gauges weren't reading right.

Yeah seriously. I knew something wasn't right. Lol
macipusy, pull the plug out of the left side of the oil pump and test the pressure from there.
