Reworking the 273 Adjustable Rockers

Rapid Robert said
No need to tear down bro. you have done more than enough already. I will (1) cap the top hole (2) pull adjuster & check inside hole (clocking to bottom threads) (3) if good then cap outside hole (on that side) (4) other side, drill 1/8 hole to oil pushrod cup (drill bit pic) (4) check if there is a second set of OE holes in my shaft(s) 90 deg to the OE banana grooves/hole. I have a bunch of shafts so I will see what I see today. RR

(1) good if not a street engine
(2) I just wanted you to see the design relating to the factory drilling out the area beneath the oil passage and hole. The adjuster no longer is touching the rocker body at that point.
The oil will shoot out from there.
(3) don't worry about this being good just plug the hole or use a set screw as a lock for the adjuster that also plugs the hole.
(4) yes
