Oil Pressure

[fishyy]

hey guys..

ive got a 96 S2 r33 and i noticed recently that my oil pressure gauge on the dash goes to 8 when i start it cold.. then it drops down to around 4 or slighty above after a while of driving..

normal or should i be worried?

that is way to high, it should read 4 and then drop to bar below that once warm, make sure u have the right amount of oil

does the lil red light come on when it does this??

you mean the circle light with the (!) on it yeah?

nope no light

checked the oil. its slighty above the max mark but 1-2mm.

btw im using full synthetic oil.. i think 60/10.. (Think)

could that be the problem?

[Greekos]

i think you mean 10/60, un less your engine is very worn and has high K's. drain that and go buy some proper oil like a 7.5/40W or as close you can get.

That sounds like the oil is too thick which is making the pressure very high when it is cold.

Skylines like oil in the 10-40 or 7.5-40 range only and synthetic if you can afford it. The best is Motul Chrono 10-40 but it is nearly $100 for 4 litres.

Nissan recommends 7.5W30

The thinner oil allows better flow to the turbo and head. Save the 10W60 for the old Holdens etc

nope no light

nah the one that is apart of the oil pressure guage its around so big... O

can anyone confirm with me the dodgy oil pressure gauge on my S2 r33? I have a fresh built motor with the lot internaly but about half an hour nto my first outing at the track the indicators went funny and the oil pressure now sits on a big scary 0 at idle but isnt making any bad sounds (knocking as it should if the pressure was correct).

When I rev it it only gets to just above the first bar on the gauge but all was working perfect before the indicators went oh and no fuse's are blown. also the oil pump is a tomei item for a RB26 to fit my 26 crank. waiting for my oil filter spacer to come so I can fit my mechanical oil pressure gauge.

any one have a similar problem with the R33 S2 oil pressure gauge?

erm ...

Cold start.. esp winter mornings... its normal for ur pressure to reach around 7 for the frist few mintues of driving....

After its warmed it will drop down ...

Idle around 2.

And when u drive should b around 3.5.

I have the offical figures in my room... i printed out the service manual.

thanks man but this was after some full blooded runs at mallala so yeah i think it might be a dodgy stock gauge as the indicators went as well so yet to put the mechanical gauge on but if you can give some psi readings that would be great, so when i finaly get back to my car to check it out i know what im lookin for
