Oil Gauge Reading Just Above 0!

Hey Guys, I am having an issue with my Oil Gauge and just wanted some thoughts / suggestions.

I have put in a new cluster because I screwed my old one up by pulling off the needles. :D

After putting it in I check and everything looked to be OK (Oil pressue reads just below 4 - half way) but after looking down last night and seeing it sitting just about 0, I thought oh crap (but everything was running perfectly!!) I checked it out when I got home and there are no leaks and the oil level is fine.

I started it up this morning and up to 4 it went, all looked good and took off for work. 10-20k's later I look down with it in mind and it is once again around 0... hmmm, about 5 mins later it is back near 4! (This is making me think that it is a dodgy gauge because I am guessing I would notice a difference between the two pressure levels - am I right??) Pretty much the same deal on the way home!

I have just replaced the turbo with an R34 turbo and have done the timing belt / water pump...

I am putting it down to a dodgy gauge however I thought it would be a good idea to post to make sure it is not something obvious / severly wrong!!!

Any suggestions or advice would be MUCH appreciated!

Thanks, Todd

This is what I just put in another post similar to your problem....

BTW it was the countersunk screws in the back of the oil pump had come loose - go figure??

Had EXACTLY this problem - drove it around for 6 mths as oil pressure and noise came and went and still made good power, BUT, it cost me.

Big ends 3&5 (i think had burnt to a crisp -totaly stuffed and crank scoured also so RODS & CRANK needed to be replaced.

Worse it was a AWD ( GTS4) RB20DET so harder to find.

Blind_Elk came to the rescue with his orig RB20DET as he put a Stagea RB25 AWD in his GTS4.

Turbine, Glenn, pulled the crank and rods from his motor and fitted to mine as my block and pistons were much better and less rego hassels.

Will be putting the rebuilt motor back in this weekend with luck :D

Get someone to check your oil pressure with a decent gauge.

It's quite common for the factory gauge to read like that.

It is usually the oil pressure sender on the motor at fault rather than the gauge itself but as you've been playing with the gauge it seems like a bit of a coincidence that it would be another problem.

I think it might just be the gauge or the sender unit. Keep an eye on it when driving. Mine sits abit under the halfway mark, then suddenly drops straight to 0.. car runs fine and had it serviced last week.

Think my problem is related to the gauge. I'll be going for some aftermarket gauges soon so we will know then!

Get a mechanic to put a master guage on it or put a mechanical guage on it yourself. if pressures are good look at the electrics. Should not see less than 20psi at idle at operating temp and should climb when the rpm increases. will peak at around 65psi. these pressures might vary slightly depending on what grade oil you are running.

I have this exact same issue....

I have always ignored it, knowing that oil pressure senders/gauges tend to be faulty and scare the shit out of their owners...............

But now I'm scared.. I might just go and check out the oil pressure next week.

      Latest round of updates on the car. I purchased and installed a SWS clutch slipper to help with 60ft times and got some second-hand good condition 275/40R17 Hoosier DR2 radials. Test and tune in November showed the tyres were an upgrade over my over 15 year old mickey Thompson's and I got a 1.8 second 60ft and pb et of 11.71 but even then, that run wasn't great due to rain and driver error (the event got called off 10 minutes later fast forward to the weekend just gone 25th of Jan and there was finally a break in the weather to let racing happen. The first run the track was slippery and only managed a 12.1@129 Second run the track was better and got a new pb et and mph: 11.54@131   Lith and I then worked out that I installed the previously mentioned clutch slipper incorrectly and its never been working, and I had just been dumping the clutch the entire time, we also noticed it was on street boost and not race boost. So I lined up for a third run with the car turned up in the first two gears, but the passengers side axle objected to clutch dumps and left the chat which stopped my weekend.   so there will be another attempt in the future once I replace the tyres as they rubbed and are stuffed now. but a low 11 should be on the cards.

      Turbos don't require pulling the motor apart so that's "easier". I would recommend the Nismo R3 turbos instead if you want to do stock twin turbo. It doesn't make as much power as the 2530s but it's only like ~50 whp off the mark and should have better response (ball bearing CHRA, slightly smaller turbo). A local that went with a Garrett G30 and 6boost manifold recently nearly burned his car to the ground after the hood insulator started melting and and burning so if you go single turbo I recommend doing a lot of research and validation work to make sure you don't do the same.

      100% is gyprock, I agree. Slip of the keyboard. Haha! I left my indicator bulbs out to save a bit of weight.
