No oil to rockers?

Lyn, Leave lifters in and spin pump, look for too much oil escaping onto cam and beliw lifter. Sounds like it?s not getting to the pushrod oil hole on the side. - thus the slot I was talking about. If it has two holes only barely slot one.

hydraulic lifters will have the oil hole in the oil band/groove of lifter,that lets oil flow through oil galleys.
the lifter that have to be slotted sometimes won't be hydraulic, will be soild roller or flat tappet the oil hole is above the band and that meters the oil sometimes it meters too good,then you have to make a small groove from oil band to oil hole which is above the oil band..
another check after you see oil galley is getting oil ar rear is to pull front lifter and check oil flow there, to verify the oil bands on lifters are lined up in the oil galley allowing oil to pass lifters

I saw a 327 that wasn?t oiling to the rockers and it
needed lash .003-.004 to oil the rockers it had longer
pushrods which changed the position of the oil hole in
the pushrod to oil hole in the rocker and without lash it would
not oil, put .004 in it and boom it oiled.
