Oil pressure gague likes to fluctuate, help?

Hey guys, when I first bought my turd, The oil pressure would always, no matter what, stay at 60. But one day turd decided to boil over when I took her on the beach so I decided it was time to change the antifreeze.
After I changed the antifreeze, the oil pressure never stays at 60 anymore. It likes to drop to 30 when I idle and as the rpm's climb it the oil pressure will climb as well.
Any solutions to this?
Any input is greatly appreciated

I had this happen to me as well about a year ago. For 20 years the needle was always in the middle. Got everything operational again and now it fluctuates according to load. Something must have been stuck for those first 20 years.
