It's my understanding that there are two oilways inside each rocker arm:
One allows oil from the hollow rocker shaft to drip down the push rod.
Oil then fills the lifter ("follower")
cup and overflows, lubricating the lifter bore and the cam lobe below.
(the other oilway lightly lubricates the valve top)
I could well be wrong. Others on the list will know more.
Also worth mentioning that each rocker shaft must be rotated / positioned
correctly on the pedestals, to allow the 4 oil holes to line up with the
oilway recesses in the rocker arms. that's only mentioned in *some* manuals.
Sorry to hear about your "nightmare". My own engine is just about to go
back together, so I'm following your ordeal closely. Hoping to observe all
this oil
flowing before startup by leaving off the tappet chest cover and valve /
head cover, no sparkplugs fitted, with the engine turning just on the
starter.
(At least that's the plan. Gotta track down a new camshaft first.)
p.s. ask yourself where all the metal fragments from the cam lobe & lifter
base have gone. You may want to strip the block and flush all your oilways.
Who said classic cars weren't fun?
cheers
