Remove oil filter,remove brass nut in center of fllter inlet,remove cover.Brass nut has siamese internal and external threads,go easy putting it together.The easiest was to fix sticky valves is to remove sparkplug and spray penetrant directly at the valve while turning the engine over with the starter...key off,plug out,spray,reach across.engine and push starter rod by hand.
