ABSTRACT:
A four-cycle outboard motor has an oil separator positioned within a head cover assembly. The oil separator is positioned within a recess of a cam cover, which forms a portion of the head cover assembly. A cover plate is interposed between the oil separator and a cam chamber. The oil separator includes a generally u-shaped labyrinth through which exhaust gases with entrained lubricant are sucked. A suction portion extends through the cover plate and facilitates communication between the cam chamber and the oil separator. An exhaust return line is connected to an induction system to draw gases through the oil separator back into the induction system.
