Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes a method that includes passing the blow-by gas to a first oil separating apparatus and a second oil separating apparatus, wherein the first oil separating apparatus and the second oil separating apparatus are physically coupled together along interfacing surfaces and in fluid communication with one another as an array, separating the blow-by gas by passing the blow-by gas through respective filters of the first oil separating apparatus and the second oil separating apparatus, removing the oil from the blow-by gas with the respective filters and recombining the blow-by gas after passing from the respective filters; passing the blow-by gas as a single flow stream from the first oil separating apparatus and the second oil separating apparatus.
