Default High oil pressure after overheating

My wife severely overheated our 03 Tahoe one day and ever since the oil pressure has been high and having problem of more oil leaking. Idle runs around 40 but heavy acceleration could jump to 60-70+. Hwy Speed is around 60. Sending unit has been replaced. Engine has 315k but doesn't smoke and runs good otherwise.

About to replace the rear main where I know it's leaking, but any ideas why my pressure is high now?

Thanks for any help.

Severely over heated? May have damaged the sensor or it turned some oil into tar and you have a blocked oil passageway.
