Excessive (isolated) 273 Adjustable Rocker Arm Tip Wear: Diagnosis & Repair?

I can't find the factory hole, if it ever was there in the first place. I don't see any sign/evidence of an oil hole for that location on the inside (shaft) side of the rocker either. Not convinced it was a factory quality control issue yet, but it may have been.

Maybe if I treat it with some "Rogaine" first, it will come out of hiding (lol).
