Just wondering if this is a normal reading for cold weather? This was normal driving home from work about 10mins ago, no hard boosting or anything, just cruising. And what exactly does this gauge tell me?

Thanks for any help.

Either you got no oil in ur sump. Or it is an oil pressure sensor problem, or oil pressure guage problem. I could keep going, but start with that first. Gauge should be reading about 4. If that guage is reading correctly and the car was not idling when you took that photo, I hope you work really close to home because you could cause some serious internal damage if you drove like that for a while.

Close - If that was indeed a true reading, I would think the motor would be dead after the first good hit.

There are two senders;

- A "on / off' type that illuminates when there little to no pressure

- A varible pressure sender that drives the gauge

If a little red light appears under the needle then you are in trouble.

I would say your like 99% of all the other Skyline owners with low readings... you have a dud sender / gauge.

Replace sender with a new one, or go after market asap. You know what they happens when pilots don't trust their gauges :teehee:

The other option is of course, the backing plate has come off your oil pump, preventing you from reaching proper oil pressure. Could get it checked out at a shop with a proper gauge.

I did oil change and everything but the gauge still goes haywire. Its all over the place when i drive, like near 0 or it will just jump to 2 then 4 then 0 again. The red light has never come on though. I was also told just to worry about the red light aswell and get an aftermarket one, so thats what ill do. I initially thought the red light was linked to the needle but ive had the needle sit where it does when the cars turned off and no light came on, and the car was still running normal. I was also told i would hear it if there was a problem with no oil pressure anyway.

Its just the std gauge/sender dying i'd say

My one does it to but i've got an aftermarket gauge aswell so i know theres no problems

But if you're worried then yeh take it to a workshop and get them to check it with a mechanical gauge.

Make sure they do it when the oil is at FULL operating temperature though, not just warm.

That happens when you're not flooring the accelarator as i have the same problem as well. Example; when driving at a normal speed like 80km 5th gear for a while, the needle just drops close to bottom. But when i shift a gear down and accelarate, it goes up again. On cold it's above 4kg/cm2 for a while, then exactly at 4kg/cm2 then warmed at 2kg/cm2. At cruising and then suddenly brake till car stops, the oil pressure drops to the same level as well.

I wouldn't worry too much as it happens so frequently on my car. No oil leaks anywhere and i change the oil at every 5000km interval.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
