CORRECTION:
With the truck off no keys in the ignition the gauge shows 20 psi. With the keys in and in the ON position but motor off the gauge shows 0.
So I still think I have high oil pressure. 40 psi idling warm. 60 psi at 2k rpm. And around 78-80+ under wide open throttle.
Any ideas?

2. Run the cable parallel to an non-vibrating, moving part and push it through the firewall and
3. attach it someplace in your line of sight but not too sloppy.
4. You can patch the illumination wires into the radio illumination, lighter or dash display(radio is the easiest).
5. Run the motor for 10 minutes and check what the engine oil pressure actually is.

Hmm
GM allows for 1 quart per 1000,which is not normal no matter what they say. You can not leak that much oil unless it is leaving puddles every time you park. If it is not soaking wet with oil under the entire engine and at least half way to the rear bumper it is not leaking all that oil it is burning it. The stock oil pressure gauge it not always accurate,you need to perform a mechanical pressure test. I doubt it has anything to do with your oil pressure.
