Just to report that, as has been commented before, the oil pressure gauge reading may not be accurate. My '90 Bronco II is a case in point. When I first bought it a few years ago, the oil pressure read on the low side. Then it started to gradually improve, but then decline again until coming to a steady reading of 'just on the right leg of the N of NORMAL'. I thought it was odd that it moved this way over time.
So I decided to install a new Motorcraft sender, down at the front of the block, during my last oil change.
Now the gauge consistently reads 'on the right leg of the M', so an 'improvement' of almost half of the NORMAL scale.
I have a bit more faith in the current reading than the old one, only because it's a brand new factory sensor and the old one must have been quite old (from the looks of it quite possibly the 30 year, 242K mile original). But the main point is that I now worry less about the engine needing a rebuild soon. It uses just a bit of oil, not much, runs very strong and gets pretty good mileage. Maybe it was rebuilt or replaced at some point, I don't know (is it easy to check if it's at least the original engine?). I replaced the heads a year ago due to coolant loss.
Try swapping out your sender, see what happens. I am glad I did.
