I had original engine rebuilt on my 71 FJ40 and oil pressure is HIGH right when you crank it over. I had it into Toyota mechanic today and he's looking into it. I read some comments that it could be the gauge or sending unit (wired incorrectly). Any ideas?

Put a calibrated mechanical analog gauge on it temporarily to get some data and see if it is actually high?
