GQ oil gauge

Hi Paul,

I have a '91 GQ Petrol and at idle mine sits around the 2 mark, whilst driving it sits somewhere between 2 and 4 depending on the what sort weather I'm driving in. Its seems to sit more towards the 4 mark whilst driving in colder weather. I believe this is the norm.Cheers,
Darren

gday pauly.
i have a 1990 gq and mine does the same i dont think theres anything to worry about—~‘¬‘¥•s’B

Same.
Mine sits between 2 and 4 when oil is hot, often closer to the 2.
I then bought a good full swing VDO gauge (added on with a "T" so old gauge still works) and guess what? Oil oressure is good, right up to specs.!

Paul, the problem seems to to be in the oil pressure sender units and are known to be a problem in Patrols. Is yours a twin sender unit in that it has both an oil pressure guage and also a low oil pressure light on the dash? Mine is like this, and when I was experiencing the same problems as you I tried to find something available aftermarket. No joy there though, the only option is original equipment Nissan but they are priced over $100 for the one on my petrol GQ.
In the end I removed mine from the block and gave it a gentle burst of compressed air and it worked fine for quite some time but it's doing the same thing again so it's about time for another dose of compressed air cleaning.
Note, I didn't push the compressed air nozzle hard up against it, I gave it a light burst from about 100mm (4") away.
Regards Andrew.

Sounds like it's normal thank god for that.

Thanks for the replys

cheers
