My newly installed used-but-ran-great F engine has a few problems. There are oil leaks which I'm methodically fixing and odd noises associated with the tranny or xfer. The real problem I think is the oil pressure. With a full load of oil the pressure is 40-40 lbs at start. After a casual drive down the hil I hit the freeway, about 15 minutes. The pressure remains god for about 5-10 minuites of freeway at 55-65 mph. Then the pressure drops to 30, with a drop to 10 when idling at a turnout. If the engine is shutoff for awhile, the pressure comes up some, maybe to 35-40.
Any ideas? The leaks do drop the oil amount, but very minimally. What should I check/replace/blow-up?????
