Crankcase ventilation system is designed to divert blow-by gases into intake manifold to be burned by engine. System is a closed type and consists of positive crankcase ventilation (PCV) valve, oil separator (Starion Turbo) and connecting hoses. System supplies fresh air to crankcase through air cleaner.
Under normal driving conditions, fresh air is mixed with blow-by gases (inside crankcase) and passes through PCV valve into intake manifold. Under heavy acceleration or high-speed driving, intake manifold vacuum decreases and blow-by gases exceed PCV valve capacity. The gases are then routed through breather hose into air cleaner and carburetor to be burned by the engine.
