An oil supply system for an internal combustion engine camshaft includes an oil distribution block configured for attachment to an engine structure adjacent to and above a camshaft, with attachment of the oil distribution block occurring after the camshaft has been installed in the engine. Fixed and movable ring segments, which are mounted to the oil distribution block, cooperate to provide the camshaft with oil under pressure, which may be used for controlling auxiliary devices such as a camshaft phaser or camshaft profile switching mechanism.
