An oil baffle, a system, and a method are disclosed for separating a gaseous component from oil in a blow-by vapor for an internal combustion engine. An example system may include a cam cover configured to be mounted on a cylinder head. The system may also include an oil baffle that may have a generally planar body with a first face and a second face opposite the first face. The first face may be coupled to the cam cover and may define an oil separation chamber between the cam cover and the first face. The oil baffle may include one or more stiffening members coupled to and extending from and substantially normal to the second face.
