Abstract: A thermal management system for a positive crankcase ventilation (PCV) system of an engine is provided. The inventive system includes a heat pipe having one end coupled to a heat source such as the cylinder head of the engine. The heat pipe is then configured to be in thermal contact with one or more components of the PCV system, such as the PCV valve or a hose. The present invention further provides a vehicle subassembly comprising a PCV valve and a heat pipe routed through the PCV valve. The subassembly may further include a hose coupled to the PCV valve.
