Mine sits around 4 in the morning for warm up. Once the oil gets to 80-90*C it will then drop down to around 2 i think. after a long day it will idle under the first bar (Not the zero bar obiously). I have been told that when its low after a long day, its ok because oil is all over your engine and doesnt need to be pumped at high pressure.

Other wise the guage is stuffed. =) See a mechanic to know when your oil pump is on its way.

interesting post guys. My 32 GTR and one of my best mates with same car, have totally inconsistent readings.

I usually have 4 on warm cruise, but some times after idle ( at lights etc) it barely makes 2. I get a bit concerned and stare at it, then 10 seconds later its 4. ( irrelevant of revs )

Never the same each day.

We have come to the conclusion that the standard guages are a bit dodge.

The best way to put your mind at rest is to put in an aftermarket guage.

I have a Greddy one on the way, will tell u how it goes.

Dont sweat, it may just be the guage.

thanx for your input guys!

started up my car this morning and the oil pressure was up to bloody 6. then it drops back to around 3. Then during hot times in the afternoon after ive been driving it, it sits at just above 1. it got me worried coz someone was telling me basically my engine is stuffed and a rebuild is needed. but i dont see any smoke or nothing coming out of the zorst, also the engine runs really smoothly without any miss firing or undue noise. so i guess its all right then.

getting the car checked out next week, so ill know for sure. at the mean time, i was told 1 bar is the low end of ok zone, as long as the oil pressure light is not on. again, as someone said, it could be the sensor or gauge, or even bad oil.

any way, ill let u guys know. cheers!

Before you rush off & start replacing anything do a search for oil pressure - there are about a bazillion posts on the subject.

A couple of things:

The oil pressure will always be higher on a cold engine thatn on a warm one because the oil has a higher viscosity when cold.

The oil pressure sender unit on the Nissans is known to be rubbish. It will send erratic pressure readings to the gauge. Hence before you get anything removed check the pressure sender unit either by substituting it with a known good one or by getting a mechanical gauge put on the car by your mechanic as a test.

The overwhelming probability is that the send unit is stuffed & the engine is fine. It will cost maybe a couple of hundred dollars if you want to replace the sender unit, but most people don't even bother doing so.

personally i would never go by a factory fittef oil pressure gauge, for one skylines always seem to have problems with them, just save a lil money mate an get a fairly good quility aftermarket oil pressure gauge. Depending on brand/ size, ur looking around 80- 140 bucks.

A lot of the Oil Pressure Gauges on GT-Rs are faulty. Mine sits on just under 3 most of the time but some days it sits under 2. Restart Car and it is back up to just under 3.

Also depends on the Oil you use. The Full Synthetic Oil will usually make the reading a bit lower.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
