PCV Hose

The positive crankcase ventilation (PCV) hose carries crankcase gases from the engine to the intake manifold, where they are drawn into the cylinders for combustion.

Symptoms of a Bad or Failing PCV Hose

  • Engine vacuum leak
  • Rough or high engine idle
  • Illumination of the Check Engine Light
  • The PCV hose should be inspected whenever the PCV system is serviced
