[AT] JD B tappet oiling

[Ray Trimble]

    After installing the head and looking at it, it puzzled me that I cannot see how oil retirns back to the crankcase from the tappet rocker arm. Iassume oil travels along the outside of the push-rods they are solid. but I see no way for it to return. There is a ventilation but I assume its for gases and it would take take quite abit of pressure to return to the top of the governor housing.
