drilled holes in each rocker arm to
lubricate the eccentric, rocker arm
shaft bore, the valve, and ball end

assists in lubricating the tappet and
push rod seat. An oil outlet tube ex-
hausts excess oil from the rocker
shaft to lubricate the distributor
lower bushing and distributor drive
gear. The oil outlet tube is located
at the No. 1 rocker arm support.
The oil from each rocker arm drains
into the push rod chamber through
holes provided in the cylinder head.
