Question: Oil Pressure
Question
When I start my Bronco oil pressure goes up to low normal, on or between the N&O. I let it warm to driving temps at idle same reading, I head out on the highway 60mph CC set and oil pressure drops just below the N, I return to Idle goes back between the N&O. During all driving, idling and reving the motor sounds smooth no knocks or ticks and is very powerfull while driving. Any ideas?

MasterOil pressure sender switches can certainly fail. Your gauge is largely cosmetic; however, the sender does provide general oil pressure information. If it is faulty, it may read inaccurately. They are inexpensive and easy to replace.
Beyond that, you do have a nearly 20 year old truck with (unknown to us) mileage, and it's a 302 cubic inch cast iron engine. You certainly will not be registering 60-80 psi of pressure at any point -- it will probably idle at 20-30 at best, but on the highway at speed you would indeed expect it to be slightly higher, with higher engine RPMs.
Start with your sender... Good luck.
