Zusammenfassung:	A valve actuation system is disclosed for an engine. The system may have at least one gas exchange valve, a rocker shaft, a camshaft, a rocker arm connected to the rocker shaft and operatively engaged with the camshaft, a valve bridge engaged with the at least one gas exchanger valve, a lash adjuster disposed in the valve bridge, and a button configured to slide on the valve bridge. The system may further include a pin fluidly connecting the rocker arm to the button and having an elongated cylindrical shaft with a first open end inside the rocker arm and a second end inside the button. The pin may also have a head connected to and a reservoir formed in the elongated cylindrical shaft. The pin may further have passages extending from the bore of the rocker arm to the reservoir, and s passage extending from the reservoir through the head.
