An oil catch can on a race car is supposed to aid in removing oil vapors from air being recirculated from the crankcase back into the intake manifold. However, has anyone ever noticed that unlike the vapor filtration system located inside the valve covers and consisting of multiple baffles with “strainer” holes, oil catch cans usually are hollow inside, thus allowing for fairly unrestricted air flow. “Strainer” baffles are meant to create a resistance to flowing air thus allowing for oil to deposit on the baffles and flow down to the bottom of the engine. The same philosophy was applied to the Greddy catch can on “Project Black” and the oil catch can strainer baffle was born. The baffle is positioned in such a way that it divides the inside of the catch can in two chambers forcing the air to flow through the strainer.
