The breather includes a rocker cover mounted to the cylinder head of the crankcase. A plate is positioned within a cavity in the rocker cover for separating the cavity into first and second portions. The plate has an opening therein for allowing the crankcase blow-by to flow from the first portion into the second portion of the cavity. An oil separator is disposed in the second portion of the cavity and includes baffles projecting from each side thereof. It is contemplated that the oil in the crankcase blow-by cling to the oil separator and the first and second sets of baffles as the crankcase blow-by flows therepast.
