After engine rebuild and 3000 miles later I wanted to check yesterday the adjustment of my hydraulic roller lifters. I used the common procedure "zero lash of the rods and then turn the rocker arm nut by 1/2 turn". Unfortunately, I found at least half of lifters without "spring effect" which means that after having reached the zero lash position I opened the valve by the 1/2 turn which can't be right .
I thought, why not doing it the other way around and tighten the rocker arm nut until you feel a significant resistance (valve is opening) and then loosen the nut by half a turn. My this method I found that for those half lifters with spring effect that it requires loosening another half turn to go to zero lash. I interpreted it that by my method I had reached approximately mid way operating range of the hydraulic lifters which I thought is good. However, I have now approximately half of the rockers in sluggish position (those which have the "zero spring lifters") and hope that oil pressure and temperature will reestablish the spring effect . I have not started the engine yet because I wanted to crosscheck with you first. Could be that I made a stupid mistake
Thanks for sharing your view and experience.
