Changed my oil. What a PITA that was btw. There is a vent right above the oil filter housing (pic attached) that turns down with a rubber hose attached that runs about 6-8 inches down that ends just above the skid plate. Is this a crankcase vent? While running I can't feel any air coming out or suction. Should that hose be routed upward so no water can enter crossing a creek or stream? Skid plate level is pretty shallow considering.
