The invention provides a PCV system for a V-type engine, where an oilmist extraction port, through which oilmist to be supplied to an oil separator is taken out from the engine, is formed at a position corresponding to the lateral center of the top portion of a chain case of the engine, and the oil separator has an oil discharge hole, and is connected to a PCV valve. A rib, which extends from the floor wall of the oil separator toward a wall opposite to the floor wall, is arranged inside the oil separator. The rib forms a dead-end portion that is open in the direction opposite to the direction toward the PCV valve side, and forms a dead-end in the direction toward the PCV valve side. An oil return passage connected to the oil discharge hole is provided with a container portion.
