Oil psi keeps rising after car is warm.

[Brentenorris]

Just as the title says, the oil psi gets higher after the car has been warmed up. This is going off the stock gauge, I know that is not a good sorce but this has just started doing this. It never got over half way regaurdless of rpm. Now it gets right before the second mark on the stock gauge. I have read numerous theards about the gauge sender but would this cause this problem?

Any opinions?

Well the gauge could be bad. Its a 21 year old sensor. I would try an aftermarket gauge and see what the pressure is on it. Then go from there.

You can replace the sensor unit that is at the Oil filter Housing.
If the problem insist, then replace your gauge unit.
That's if you want to keep your car as (STOCK).

I would replace it with an After Market unit, which is more accurate and will let you know exactly where your oil psi are at.

Replace the guage/sensor - I went with AEM (Amazon.com for cheap prices).

Thanks for everyones opinions. I'm goiong to replace the gauge with an aftermarket unit. Ive watched the gague and will not do it untill it get past 3k at highway speeds. (anything above 60mph) Should i go with mechanical or electrical unit

If you just want to replace your stock oil pressure send unit you can buy one from here:

1G Oil Pressure Sensors

+1 on replacing the sending unit..the gauge can only read what is being sent to it..

Id like to know this answer also.

I have an autometer electircal pressure guage. Can I just wire the input wire from the guage to the sending unit and just remove the wire from the stock harness?

I personally like the mechanical gauges but this is a matter of preference.

On my cars, oil pressure was always highest at cold start. My old hyundai was around 75-80 psi at start up, then warm at idle id say around 20-25. So getting higher just don't right unless something is seriously going on.

I liked my electronic gauge. Didn't have to deal with running that line from the oil pressure location to the cabin.

When i first got my last Talon my stock oil pressure gauge was all over the place. I cleaned the electrical connection for the unit and my pressure needle started acting normal again.

I have an AEM Elc. And it works grate.

It is faster then Mechanical.

But. It's up to you, there are good reviews on both of them.

Personally,,,,, I would go with an electrical....

You need to use the After market sensor and gauge.

You can't use an after market sensor with your stock gauge, nor the stock sensor with an after market gauge.

Wires, does not matter which ones you use, You can use the stock lines or different one..
I wouldn't recommend to use the stock lines which will be more labor.

Hope this helps.

It's ok man. Well i went and got a cheapo mechanical oil psi gauge. To my surprise the oil psi at a cold start jumped up to 80psi then dropped to about 55 after it was compleatly warm the oil psi held at 11psi. I still need to drive it. This problem only happen at highway speeds over 3k. My bs delete consist of cutting the bs off and turning the bearings in the block the ofh is not ported. Thank you all for the help.

Well it's the gauge sender going bad. Drove around last night for a lilltle while and everything is checking out ok. Thanks to all the people that helped. How do i tag this thread as resolved?
