Blow-by system
The oil vapour and gas recirculation system is a closed circuit.
In the event of engine malfunction causing an anomalous increase in oil pressure, oil vapour from the heads is
ducted via the pipes (A) to the vapour separator (B).
In the vapour separator (B), a portion of the vapour condenses and drains into the oil tank below, whereas the
remaining gases are aspirated by the vacuum generated by the engine and ducted via the pipes (C) to the
bellows (D) ahead of the throttle bodies and into the intake plenums.
