PCV System: 1.6L

  1. PCV system maintenance consists of inspecting hoses to ensure they remain clear and in serviceable condition.
  2. The vacuum orifice in the intake manifold should be checked on a regular basis and cleaned as necessary. System performance is dependent on engine sealing. Faulty seals or an excessively worn rings and valves will cause sludge build-up or oil contamination.
