How do you adjust the valve on a hydraulic lifter?
When adjusting the valves on an engine with hydraulic lifters, you are not really setting the lash or clearance–you’re actually setting the preload on the lifter through the pushrod and rocker arm.

When do you switch to an adjustable valvetrain?
If we switch to solid lifters it is mandatory that we convert to an adjustable valvetrain (I would also say that converting to adjustable valvetrain is mandatory in ALL racing applications as well as any application where we want to have accurate control of our valve lash setting). Not doing so is asking for serious problems!
When do you know you need to adjust a valve?
You can only properly adjust the valvetrain after removing and closely scrutinizing each of the rocker arms, pushrods and valve stems (the cylinder heads do not need to come off at this point).
