Probably about time-rocker adjustment

Spinning the push rod is not the proper way to adjust a hydraulic lifter. Get the lifter on the base circle. Loosen the rocker while lifting the pushrod up and down. When u feel clearance start tightening the adjuster till u take out the play. Then tighten the additional 1/4, 1/2, 3/4 or 1 full turn. Some may 2 turns. I have only ever needed no more that 1/2 turn. In fact when I measure the preload I adjust it to .006 thou. Kim
