Oil pressure reading high

[99bluegst]

ok the first thing it happen to my car was that the oil light was flashing during idle so after that happen, now everytime the car pull hard the oil pressure needle goes all the way to the top, it only happens when the car pull hard
please help!

thats supose to happen at wot you can see up to 100psi or more

> 100 PSI oil pressure IS high. Get a REAL gauge installed and see what it's ACTUALLY doing.

I assume after the oil light flashed you stopped immediately and checked your oil level?

my car has a mechanical autometer oil pressure guage and i see over 100 psi alot... ( during high rpm and during warm up. ) I dont think your problem of quote "high oil pressure" is uncommon. - usually the oil light comes on due to lack of oil volume ( low level ).

I agree with My98GSX my fresh built engine is seeing around 80psi when driving and when your pulling hard its over 100 psi. my guage is tapped at the bottom of the engine, so would be less at the top of the engine. not sure how much though

+1 with rallyturbo

Those of you who have really high oil pressure and no balance shafts, I hope you ported the oil relief valve well.

Are the balance shafts removed? If they are it will cause higher oil pressure.

No the car is all stock!

But why is doing it right now it wasn't doin it before Or is it becuase of the type of oil, I use pennzoil 10-40,or maybe the sender unit ??

Use 10-30 or 5-30 is more thinner and can help alot.
You should check your relieve valve it can be bad maybe it got stock and is not opening.

Yes I stop and checked and the oil level was right.

But now the light went away And the issue is the needle,
I'm try to explain, there's 3 levels on the oil pressure guage bottom, middle, top. So when I pull hard at full boost the needle pass the top level,

Use 10-30 or 5-30 is more thinner and can help alot.

Where is the relieve valve?

The second pic shows it, the bolt and all internal is the relief valve,
it is very weir to go bad, but it can happen, Here is it.

It is located in front of the engine underneath on the filter housing, Here is another one that shows where is located.

Maybe your sending unit on your OFH is old and messed up and reading wrong,usually high oil pressure occur when you do a BSE,I recommend getting an electronic oil pressure gauge.
