high Oil pressure

[maswift]

I have a 1987 260/5.7 it has a half fresh water cooling system, I recently changed the risers seawater pump and did a tuneup. I bought a aftermarket seawater pump and didnt know they were left and right hand turn so i hooked it up backwards and overheated the engine to the point of antifreeze blowing out of overfill. Got it back to marina fixed the problem, changed and flushed antifreeze and oil and filter. Now when idling my oil pressure is at 60-70 and when cruising at 3000-4000 rpm is steady between 70-75. No strange noises, oil is clean, and has run fine for about 3 hours now. Just concerned about oil pressure anyone have any suggestions? Is this normal? Thanks in advance.

Bad sender or gauge, remove the elec and install a mech gauge to test reading.

Sounds good to me.

Dock, THe pressure sounds good or installing a mechanical gauge? Thanks

The oil pressure sounds fine. You can't go wrong by installing a mechanical gauge just to be sure.

Thanks Dock, I read that normal operating was 30-60 at idle but i dont remember it being that high before maybe just me being worried after the overheating. Thanks Again

If memory serves me correctly, I think spec is 30 to 50 Lbs @2000 rpm.
