Abstract
Apparatuses including an oil separation device are discussed and shown. The oil separation device can optionally include a jacket arranged between an inner housing and an outer housing. The inner housing has an inner cavity that receives a filter configured to separate the oil from a blow-by gas. A first inlet port is positioned to extend generally tangentially relative to the jacket and a first outlet port is positioned to extend generally tangentially relative to the jacket. The oil separation device can include a first cover and a second cover coupled to or integral with at least the outer housing at opposing end portions. The first cover and the second cover are configured to receive the blow-by gas and to pass the blow-by gas as desired.
