The Closed Crankcase Ventilation system (CCV) requires the replacement of the fumes disposal filter. The service interval of the Closed Crankcase Ventilation system (CCV) will be affected by the following items:
- Engine load
- Soot concentration
- Condition of the engine
The Closed Crankcase Ventilation system (CCV) is equipped with a service indicator. If the fumes disposal filter becomes plugged prior to the normal service interval, increased restriction of the filter will cause the vacuum to become positive.

Reset the service indicator by using the following procedure:
Resetting the Service Indicator
