OVERVIEW
The engine crankcase is ventilated through a positive crankcase ventilation (PCV) valve located on the camshaft cover. The crankcase gasses are transferred internally to the positive crankcase ventilation (PCV). The positive crankcase ventilation (PCV) valve prevents reverse airflow into the crankcase.
