CRANKCASE VENTILATION SYSTEM

The Engine Ventilation System passes crankcase vapours, via the Engine Vent Pipe, to the Cam Support Cover,
where separation of oil and exhaust gases occur. The oil drains into the Cylinder Head, via the Camshaft Support.
The gases pass through the Primary and Secondary Vent Hoses to the intake system, and are consumed during
the combustion process.
