is what I posted in the original post the way to adjust them properly?
No, the factory recommendation is to take out the slack with the adjuster with both valves fully closed, then tighten the adjuster an additional 1 1/2 turns. The lifter plunger will retract slowly to the midpoint of its travel. Most of us consider this to be too much preload, and the conventional wisdom is to tighten the adjuster about 3/4-1 turn beyond the "zero lash" point. Do this adjustment with the engine stopped, not running, with each cylinder at top dead center of the compression stroke, and by the time you get around to all six cylinders by turning the engine to TDC compression by hand, the lifters will have assumed the proper retraction. Ignore advice about trying to do a running adjustment on hydraulic lifters- - - -it doesn't work.
