Oil Pressure - Very High!

[skyliner33wa]

Hey all,

I know this has been asked a lot but about a day or so ago i noticed that my oil pressure guage is showing 8 and over (going past the last mark on the guage) should i be worried. I thought i may have had something to do with my white face dials getting installed and them buggering up the needle but they didn't cause it was fine after getting the dials installed.

I have not checked my oil yet, i will do that, i have only had the car for a month.

Cheers

Kris

Kris,

Really high oil pressure is usually due tot he wrong grade of oil being used.

What is the pressure at idle when warm? And what it is at cruising speeds when warm?

If in dought, dump the oil and filter and change it to something the guys on here recommend.

Cheers

i would get another guage and check the pressure comparing to the factory one. you might find there could be a short in the wiring causing the needle to read that high.

just a thought.

I would suggest it's the sender. Disconnect the wire from the sender and see what happens to the gauge. Then try earthing the wire.

(had a similar problem in my R30 - oil pressure without the engine running, just with key in 'ON' position)

when is used a 10-60w Castrol formula R was too thick oil pressure was higher than normal...but nothin spastic..

sounds like the factory gauge/sensor playing up as you mentioned it only just started happening, i.e it was fine with the same oil....

but check oil to see level, and for contamination (water or fuel etc.) and buy an aftermarket gauge for more accurate indication.

if u r oil pressure is realy high ( have it checked with a good pressure gauge ) the pressure release valve maybe stuck , its on the oil pump .

if u r gauge is reading right 8=112 psi thats to high .

i had same problem, it read 8bar + even when engine off, i tried cleaning out with compressed air, no luck, biff sender, try another

My Oil pressure reaches high's only in the mornings when car is cold. I hesitate to drive because the needle just keeps rising unless i put the car in neutral wait for it to drop then try driving again, is this normal

after engineis warm it sits in the middle.

Normal , the oil is too thick when cold .
