Those two events do not happen at the same time. the pinion, oil pump gear and breather are the only gears that have a reference with the flywheel timing mark. " once breather valve is correctly timed, position of flywheel timing mark and breather valve timing mark,registered in slot of breather sleeve gear, can be disregarded when installing timing gears." RE 1978 service manual. hope this helps.
