Crankcase Ventilation Systems


Crankcase Ventilation Systems

The positive crankcase ventilation system (PCV) routes unneeded and potentially harmful gases from an engine’s crankcase back into the combustion chamber. Wells produces one-way PCV valves that routes these gases back into the combustion chamber.

If the Crankcase Ventilation System is not functioning properly, a vehicle may experience:

  • Excessive high idling
  • Poor performance or fuel economy
  • Check engine light is illuminated
