Abstract
An oil passageway structure for an internal combustion engine which provides a greater degree of freedom in design, prevents oil leakage outside the engine, and avoids the need to change the respective shapes of a cylinder block and a cylinder head, with a concomitant reduction in plant investment. The oil passageway structure includes an oil pipe laid between a passage extending on the downstream side of an oil pump on the side of the cylinder block and an oil control valve on the side of the cylinder head. The oil pipe is positioned inside a chain chamber.
