You did this as well correct?
"rotate the engine in the normal direction of rotation until the exhaust valve begins to open. At this point,
adjust the intake valve to ZERO LASH with no pre-load at the lifter, then tighten 1/2 more turn. Rotate the engine again until
the intake valve has fully opened. Now you can adjust the exhaust valve to ZERO LASH, then 1/2 more turn. Repeat this
procedure until each cylinder is completed."
I adjusted the rockers that way today and it didn't change anything. For some reason just the one rocker/pushrod combo is different from the rest. When I have the adjuster backed all the way out and the pushrod in place, I can't turn the pushrod with my fingers without the lifter turning slightly as well. If I pull upward on the pushrod very slightly as I am spinning it the lifter stops turning in the bore. So, since it looks like the pushrod is just starting to push down on the lifter plunger without having set any lash, instead of doing the half turn to set the lash I only did a quarter turn.
