There has been some debate over this, mines running at about 80 psi at about the rev range you run at when cruising at 100k in 5th (no im not suggesting that oil pressure is relative to speed... its just to give you an idea of the revs, obviously it goes up when boosting and down when idling...) Anyway some people say this is too high, and some say its normal... I would really like to know for sure!!
HELP!!

OK guys...Whats the normal oil pressure in psi for a 4G63T?

G/Day Kiwi oil preasure is governed by the following
0 condition of your motor : good ,worn ,clapped out
1 engine revs
2 oil temperature
3 grade of the oil you are useing
The stock opg is electric . (in a staz ) Do you have a mechanical gauge ??

A good rule of thumb is 10psi of Oil pressure per 1000Rpm, so 80Psi at 7000Rpm is ok :)
What Oil are you using exactly ? Eg, Brand ? Type and Viscosity ? Cause you can lower it by trying an oil with 12% less cSt @ 100C, but same Weight and equal if not higher HTHS :beer

Computer games don't affect kids I mean if PacMan affected us as kids, we'd all be running around in darkened rooms, munching magic pills and listening to repetitive electronic music :D
High oil pressure is ok though, justs costs you power :)
If you can be bothered checking the 'Relief valve spring/piston' isn't jamming, then that's where I would look :beer

Are you sure you took out the "Oil Pressure Relief Valve" and not the "Oil Cooler Thermostat" ?Grifstar wrote:no im using the sender that came with the pod guage... i will definitly check that valva again though... I took it out and had a look a little while ago and it seemed fine, but how do you tell for sure??
But, yes take it out and check that the Piston wall surface is clean. Then you should check that the Bore wall where the little Piston sits in, is also 100% clean so that the relief Valve/Piston moves freely and isn't jamming.
You will have to remove the Oil Cooler Lines, and remove that whole section which has the Oil Filter on it to check this........
You will also loose some Oil from this so make sure you re-check your Oil level afterwards.
