Hi Yellow rose,
I called comp last week and they told me there steel rocker does not oil thru the adjuster cup bolt.
They just changed out to the cup bolt. Said I should oil like a chevy. They have steered me wrong before with there tech line.
The old set I have here gravity oils. Other company's I can't comment on. The reason I started this post to see whats new in the last 12-13yrs. I am using the good stock type shaft as in your cool rant.
Thank you for your post. It came up as I was answering your prior one.
Rick
