Low oil pressure??

[Ronin 09]

I've got an R33 GTS-T, I've potentially got an oil pressure problem... the gauge sits low at idle (at about 1), but when up in it sits at about 4. Does anyone know if:

1. nissan oil pressure gauges are dodgy

2. nissan oil pressure sensors are dodgy

3. GTS-Ts have dodgy oil pumps.

From the way it drives it seems to be fine.

If it is the oil pump what on average is the cost of part/repair?

Thanks.

Ronin 09,

As far as I know, Nissan don't have dodgey senders/gauges etc. However it is common for the oil pressure sender to fail. This is usually due to poor maintenance rather than a defect in manafacturing.

With regards to your pressure it does seem low. Idle should be around 2 at 6k rpm it should be around 6. The first thing I would do is try an aftermarket gauge. Then replace oil sender, then go from there.

Also check that you are running a high quality synthetic oil Eg Mobil 1 5w-50w. If you search the forums you will find many other suggestions for oil.

The Skyline senders are well known to give low readings.

Like hitnrun said, more of a maintance thing that a manufacturing thing.

Mine did this once. I gave it a drink of good qual oil and a change of filter and haven't looked back.

If you start to hear a rattle, turn it off REAL FAST !! :uh-huh: :uh-huh: :uh-huh:

Thanks guys, haven't heard any spooky noises or anything, so i assume it is the sender. Sometimes tries to stall at idle, but i think the idle is set too low (450-500 RPM)...

I've just got my car fresh from importing, and have not had a chance to change all the fluids yet. Problem is i'm pretty useless mechanically, and all the shops are closed till at least the 6th. I'll report back when i get the fluids changed / a service and get them to look at the pressure sender.

Any recommendations of shops to get my car serviced in Melbourne? Using Evolution R, but they seem pretty $$!

How did you go?

I have the exact same problem...

[Ronin 09]

Dremen, i've had a couple of oil changes, and it has steadily gotten better. Apparently the sensors are quite sensitive to crap oil. I've used Mobil 1 5-40W, and just last change went to Motul 3000 15-50W. Just use a quality oil, you should be right

Cool

I just changed the oil and filter then...... Mobil 1 10-40W

I will see how it goes.....
