A valve operating mechanism includes a pin housing housed in a lash adjuster and a lash adjustment chamber. A sync pin is slidably received within the housing between an activating position and a deactivating position. A ball valve assembly is provided within the housing for communication with the chamber, and is moveable between an open position and a closed position. The valve operating mechanism is operable in an active mode and a deactive mode. In the active mode, the sync pin is in the activating position, a valve is in an active state and the valve operating mechanism is configured to adjust valve lash. In the deactive mode, the sync pin is in the deactivating position and the valve is in a deactive state. The valve operating mechanism is configured to generate valve lash to allow the operating mechanism to move between the active mode and the deactive mode.
