The valve train assembly includes at least one tappet that is housed in a rocker housing with at least one rocker lever. The at least one tappet is engaged to an actuator that is operable to change the tappet from a first configuration in which all cam lobe motion is imparted to the rocker lever for opening and closing the intake and/or exhaust valve, to a second configuration in which less than all motion of the cam lobe is transferred to the rocker lever.
