ABSTRACT:
An arrangement for heating the blow-by gas system of a water cooled type internal combustion engine by providing engine coolant conduits in heat exchange relationship with the blow-by gas hoses and PCV valve. In one embodiment a water jacket surrounds the PCV valve. The heat exchangers between the blow-by gas system hoses and the coolant hoses are parallel adjacent conduits in one embodiment and concentric conduits in another embodiment.
