(1) Crankcase breather (2) Filter base and filter for fumes disposal (3) Air cleanerThis engine is equipped with a Closed Crankcase Ventilation System (CCV) that is used for capturing the fumes of the crankcase. Fumes from the crankcase exit the engine through the crankcase breather. The fumes from the crankcase are collected in the filter base. The engine oil is separated from the fumes from the crankcase in the filter base. The engine oil collects in the filter base and drains back to the crankcase through a drain line in the bottom of the filter base. The fumes from the crankcase are directed back into the air cleaner assembly in order to be consumed by the engine.The CCV filter base has a service indicator that will indicate when the filter needs to be replaced. If the filter becomes plugged the engine will not be able to relieve the crankcase pressure. This will cause the engine to develop external oil leaks. For more information, refer to the OMM, "Closed Crankcase Ventilation (CCV) Filter Service Indicator - Inspect".
