A cam cover for a motorcycle engine comprises a fluid passageway for crankcase ventilation, a camshaft support, and a crankshaft support. The fluid passageway is routed such that the camshaft support and the crankshaft support are positioned to one side of the fluid passageway. Additionally, the cam cover comprises a piece of sheet material that partially bounds the fluid passageway and creates a settling chamber for separating oil out of mixture with gaseous fluids being vented.
