Abstract
An oil tank uses centrifugal movement of oil to separate blow-by gases. The oil tank has a tank body with an internal oil chamber. The oil chamber is spaced from the walls of the oil tank. The oil is delivered to the oil chamber and the oil swirls along the inner wall of the oil chamber in a helical pattern thereby allowing separation between the oil and the blow-by gases. The oil settles in the bottom of the oil chamber, which is in fluid communication with the region defined between the tank body and the oil chamber. The oil chamber is placed in an off-center location relative to the bottom of the tank body.
