No oil coming up through my push rods.

With most lifters having oil holes these days, and most pushrods having oil holes these days, it is possible to have "oil-thru-pushrods" on a LA engine. It hurts nothing. However, that is not how the rocker arms get oiled. All the oil the rockers need should come from the shafts.

Not sure I agree that it can't damage things - in the case of my Magnum, the amount of oil that spewed out of the hollow lifter-pushrod-rocker seat combo was enough that the lifters couldn't pump up with enough oil to keep the valvetrain from loosening up and clattering. Something would have gotten fubar'ed if I kept it like that.

Had it been an LA top end with the same combination, it would probably have been a similar situation, if a bit less pronounced due to the smaller hole on the rocker.
