Oil Pressure Guage Light

[94GTTR]

i have an R32 GTR, about 2000k out of a rebuilt and the red light on my oil pressure guage turned on.

i checked the oil and it was a little low and needed a change so i changed the it yesterday (castrol edge 10w-60w) and the light is still on...

is the light for oil level or low pressure? i'm worried can anyone shed some light on the situation?

cheers.

I would be very concerned. Get it towed to the workshop that did the build to check it out. The low pressure light is normally very reliable.

Red light mean NO oil pressure. I would be very concerned.

Only quick test you can do is put another aftermarket oil gauge and sender unit on the motor to confirm its not the origanal oil sender unit and guage. The oil sender units have been known to not show oil pressure properly so check it out.

If you tried the above and still no oil pressure, youve got a prob with your oil pump bud.

thanks mate,

but what i don't understand is that there is still a pressure reading on the dial itself, between 0 and 2 on idle and with higher revs it goes to around 4 which is what i thought was pretty normal?

also wouldn't "no" pressure affect oil or water temp? i have an aftermarket water temp and the car runs quite cool...

i hope it's not the pump, it's a nitto and i paid 1200 odd for it :-/

Sounds like a faulty sender for the light, when they go they are usually stuck on, they short out in the body. I'd go to a workshop and get them to check your oil pressure, but if your gauge is showing 2 to 4 [which is about right] then I'd say you have nothing to worry about - but get it checked!!!!

If its the oil light sender, around $20 will get you a new one. By the way they are generally - not always, but generally - set up to turn on at 7psi [0.5kg/cm2] or less. So if you don't make 7 psi then it will be on.
