  1. CONSTRUCTION


    1. By using a PCV system which directly intakes blowby gas from the crankcase to the No. 1 ventilation case, ventilation efficiency has been enhanced and oil deterioration is reduced.

    2. A Labyrinth structure is used for the oil mist separator of the No. 1 ventilation case. By enhancing the oil mist collection rate, oil consumption and the buildup of deposits have been decreased.

    3. By integrating the PCV valve into the cylinder head, the vacuum hose has been discontinued and the PCV system has been simplified.
