Abstract
A cam cover for an overhead cam engine has first and second oil separators connecting the crankcase with the engine induction system high and low vacuum portions as part of a crankcase ventilation system. The separators each have a floor sloping toward the outlet and forming a sump with a drain to the crankcase. A large slow flowing separation chamber precedes the sump. An optional inlet tube is angled down with a large inlet facing away from the oil splash. A shelf may extend between the sump and the outlet end to deter oil carryover to the outlet. Optional PCV valve and oil filler locations are shown.
