mopar valve adjustment

[CMcAllister]

Been awhile, but on hydraulics, we always just went to zero lash. Preload beyond that made it possible for the lifters to "pump up" at high RPM and prevent the valve from fully closing.

Might be a hillbilly way to do it, but we would run the valve adjustment just like a mechanical cam, but would loosen the adjustment a touch until it had clearance, then spin the pushrod with fingers while slowly tightening the adjustment. When the pushrod got snug, stop. Done.

Like I said, been awhile.
