None of this equates to you oil question. Don’t want to scare you, but having a rocker seize to a shaft can be BAD. The galling can progress exponentially. Now that is a hard stainless rocker on a hard shaft. Also on the next generation the bushed the rocker. Funny, that shaft was and has never been orientated correctly. That rocker is welded to the shaft, so it hasn’t moved. Aftermarket rockers have a groove like a main bearing groove. So the location of the oil hole doesn’t matter.
