Default Proper Oil Pressure?
Does anyone know what the normal oil pressure is at idle, and at 2500 rpm?

I am sitting at 90psi idle 120psi at 2500-3500 rpm.

Thanks in advance

Fully warmed up, the oil pressure should be near 2 on idle. By 2500 rpm, around 4 bar. Oil pressure should not go higher than 5 bar, fully warmed up.

90 psi is 6 bar. You have VERY VERY high oil pressure.

Well, sounds to me like I may as well go ahead and pull the oil cooler housing. I'll keep it updated.

What does it show up as on the stock oil pressure gauge? Are you using an aftermarket one in PSI increments?

One sign of a sender unit going bad is that it will give out very high readings.

No, I'm using a Matco, manual pressure gauge that reads from 20psi to 240psi. So I KNOW that the reading is accurate.

Changed it out with an older unit, and checked the new one, they seem to be working normally. I think the cooler may be clogged, and/or ruptured. See my post on the "other" oil pressure woe thread.
