Hi guys,
Tip from an old-timer......remove the oil pressure relief valve....the big bronze nut, pull spring and piston, check piston for wear, replace or polish if worn, squirt in oil, rotate prop, repeat, reassemble, start engine. That was my once a year ritual when I returned from europe to fly for the summer. No heavy lifting, no special oil can connections or other B.S..
