The wind quit, the rain quit and the ceiling went up to 3000 so I went flying. I was about 20 miles from home and I noticed the oil pressure at 80 lb. The PO had marked the gauge at 60 lb and that was about the max. Good SW mechanical. I headed for home and took the road rather than across the bay to our island. At idle it dropped to 60. Engine is a 320 a2b with 1300 hrs and compression 72 74. Has always had good maintenance. I changed the oil 2 hours ago and it is very clean. Both screens were spotless. Oil temp was 160 at cruise. So I guess I have a stuck plunger/spring. Been there on cars. I think there is also a thermostat for the oil cooler. Guess that is the next project, any tips? A fellow at the airport said pour some of that stuff in, pointing to the gallon of MM that came with the plane. I'm not here or there with that.
