The crankcase ventilation system comprises:
Positive Crankcase Ventilation (PCV) valve
Positive Crankcase Ventilation (PCV) hose
Crankcase Ventilation (CCV) hose
The PCV is an electrically heated control valve that allows the gas from left hand cylinder head to flow into the air intake.
The PCV valve is electrically heated to allow it to remain operational in cold climates. The PCV heater power is fed from
the fuel pump relay, therefore heating is always active while the engine is running. The current supplied is internally
regulated by the PCV.
