R32 Oil Pressure

[rosco 104]

Hi guys,

I'm after a bit of advice, I have an r32 gts-t (93), I have noticed my factory oil pressure guage reads quite low (nearly back to 0 on idle, and only just above 2 for normal driving), is this likely to be an oil press sender issue? It runs fine, plenty of oil etc...

Also another quick question, I occasionally get a small hesitation when I roll off and back on the throttle, as in, I back off slightly, and then when I squeeze the pedal back on it gives a small miss, and then pulls away fine, not the end of the world, but it never used to do it.

Any help would be great!

Cheers.

Oil pressure Sender units are notorious for giving up the ghost, have someone check your oil pressure with a mechanical gauge. Flat spots are generally caused by a lean mixture, you may have an air leak into the inlet manifold.

I'm seeing the same thing with oil pressure on my 32, keen to know how u go fixing this

...I have noticed my factory oil pressure guage reads quite low (nearly back to 0 on idle, and only just above 2 for normal driving),

I notice the exact same thing with mine, could it be normal for a R32 GTS-T. My oil pressure does however rise to 4 after it has fully warmed up though.

mine has a mind of its own!! your right though, when it warms up it generally gets higher, for me it reaches the 2.5 makr i think.

im asasuming the sensor is dicked..

[R32_GODZILLA]

Mine drops as it gets warmer.

On cold start it will idle just on/bit over 4, when warm on/bit over 2.

Only ever rises as revs rise which is expected.

i also notice the guage gets lazy around oil change time(5000kms)

My motors healthy (compression tested etc..) but the oil pressure gauge always reads low.

On start up when cold it will be just under '4' on the stock oil pressure gauge, and it only gets lower as it gets warmer.

When cruising at a consistant speed its quiet low, but at about 100km/3XXXrpm its in between '2' & '4'..

I don't really worry about it to much as I have been told the stock oil pressure gauge is useless, so I won't be able to get an accurate reading till I get a decent after-market oil pressure gauge.

Yeah mine went heaps low after I serviced it.

Was slightly worried with it being so low..

Very normal guys, but don't assume anything. Get it tested..... not worth stuffing your motor over.

[TurboX]

Yeah, do like I did and ignore it thinking its a sender........

You will be sorry like I was too....

Hi again all,

Well I have fixed the problem, turned out to be an interesting one!

I had just replaced oil and filter before I started having this problem, and I used penzoil 10w30, which was a mineral oil, and as I read some of the posts is not the stuff to use, so I went to supercheap and got some fuchs 10w30 synthetic and chucked that in just to be safe.

Took her for a drive, and to my surprise, oil pressure is now back to normal readings on the guage! Not sure how that works being the same viscosity of oil and all, but thats how it hapened!

Cheers,

Rosco.
