Default Oil pressure

I have a 87 3/4 ton suburban 4x4. It runs great except that it has high oil pressure. I changed the oil, sending unit and am about to change the gage. I don't think any of these things are the reason for the high pressure. Anybody got any suggestions.
thanks[]

Possibly a restriction in the PCV system.

Default RE: Oil pressure

So i changed out the PCV and the pressure was ok for a day and today on my home from fishing the stupid thing pegged itself to 60, The pressure seems really inconsistent though. I think i am going to change the gage. If that's not it does anyone have any other suggestions.
thanks
