Claim:
A filtration system, comprising: a valve lid defining a chamber, the chamber being configured to extend substantially in a second direction; a filter element associated with a lower portion of the chamber; a passageway in flow communication with the lower portion of the chamber, wherein the passageway is configured to provide flow communication for a mixture of oil vapor and crankcase fumes flowing into the chamber substantially in a first direction and substantially upward direction, the first direction being generally orthogonal to the second direction; a valve cover in flow communication with the valve lid, the valve cover forming a cavity and an opening of the passageway, the passageway fluidly connecting the cavity and the filter element; and a breather element disposed within the passageway upstream of the opening; and wherein the chamber is configured such that the flow of the mixture into the chamber results in at least a portion of the oil vapor collecting in the filter element, and at least a portion of the crankcase fumes flowing through the filter element.
