Tell us more about the engine? Recent rebuild, are you sure it's a hydraulic cam? How are you setting the preload? If not a recent rebuild how old is the engine?

adjust rockers down till pushrod just turns on the ball then turn adjuster one whole turn then tighten, this should be it and once motor is run in redo all of them.
make sure the rocker is off lobe.

this how i do it and it works perfect.
