Abstract: An oil separation baffle is mounted in an oil gallery of an internal combustion engine. A lower section includes a bottom wall and side window openings. Crankcase gasses flow into the side window openings, through the lower section, and through the top opening. An upper section includes a plurality of ribs extending horizontally between a front side wall of the upper section and a rear side wall of the upper section. The plurality of ribs are vertically spaced apart from each other and extend from a first wall of the oil gallery toward a second wall of the oil gallery to an opening defined between a distal end of the rib and the other of the first and second walls of the oil gallery. The bottom planar wall separates larger oil droplets and the ribs separate smaller oil particles from the crankcase gasses and return the oil to the crankcase.
