Pushrod Tech (Page 2/2) La fiera MAY 29, 10:53 PM quote Originally posted by claude dalpe: I start my explanation again, when you have the right push rod length the rocker does not move on the valve stem or very slightly but in general the rocker remains in the center of the valve stem which gives normal wear of the guides Claude, you'll always have the rocker moving on the valve stem. If the rocker is not moving it is not lifting the valve.
