That could be be changed over and the hole blocked, but my RAS rockers feed oil through a cutout in the adjuster thread. Not sure what kind of issues that might cause trying to oil the adjuster.
I know the adjuster area on the Norris rockers isn't nearly as thick as the MP rockers I have. I'm not a fan of aluminum rockers but maybe I should just use the MP rockers and have you convert them to ball adjusters.
