Mike,because of all the issues with hydraulic lifter is is more important to use the method we suggested.Put the exhaust in the proper just starting to open position,loosen the intake adjuster untill you feel free lash movement,spin the pushrod and tighten the adjuster untill the free lash is gone and the pushrod just contacts the lifter cup,then preload by tightening the adjuster 1/4 to 1/2 turn or the specific preload recommended by the manufacture.Lock the adjuster with the jam nut.On the same cylinder rotate till the intake valve opens and closes over 1/2 way and repeat the process on the exhaust.Many people adjust hydraulic lifters incorrectly and don't get the preload tight enough and the lifters are noisey and many times the lifter doesn't pump up and push rod may jump out.Sometimes they adjust them too tight and collaspe the lifter making it hold the valve open and damage the valve train componants including the cam.Hopefully I have been helpful in explaining,a lot of damage has been seen by incorrect processes.If your concerned about getting the lifter in the correct position you can uue the pushrod with the adjuster backed off and follow the lifter and cam movement with the pushrod.thumb:
