Abstract: Apparatuses, systems and methods are disclosed including a breather remote from an engine housing. The breather can be configured to be in fluid communication with a blow-by gas of the engine, and an oil separating apparatus. The breather can be configured to separate oil from the blow-by gas with a first filter media. The oil separating apparatus can be configured to be in fluid communication with the blow-by gas and can be configured to further separate oil from the blow-by gas with a second filter media. The breather and the oil separating apparatus can be configured to be coupled directly together such that an outlet of the breather communicates directly with an inlet of the oil separating apparatus with no intermediate component therebetween facilitating communication.
