An engine includes a variable valve timing device coupled to a camshaft, which operates within a cam chamber of the engine. The variable valve timing device includes a hydraulic pressure switchover valve having an elongated valve body. The switchover valve is disposed outside the cam chamber and is oriented such that a longitudinal axis of the elongated valve body lies generally parallel to a rotational axis of the camshaft. In this manner, the engine size can generally remain compact while still employing a variable valve timing device with a switchover valve.
