An improved lubricating and valve actuating system for an internal combustion engine having plural valves per combustion chamber. Two valves are operated by the same camshaft, one directly and the other through a rocker arm. A lubricating system is provided that includes a passage that extends through the rocker arm pivotal axis and the sliding support for the thimble tappet of the directly actuated valve for lubricating both actuating mechanisms.
