  Hose Air Inlet Hose Blowby Gas (Lower), Hose-Blow By, A

• Description:

  A blowby gas hose is a hose in an engine’s crankcase ventilation system that carries “blow-by” gases from the engine crankcase back into the intake system.

  What are blow-by gases?

  During combustion, a small amount of gas escapes past the piston rings into the crankcase. These gases contain:

  • Unburned fuel
  • Air
  • Oil vapor
  • Combustion gases

  If pressure builds up, it can cause:

  • Oil leaks
  • Sludge buildup
  • Poor engine performance

  What the hose does

  The blowby hose connects the crankcase or valve cover to:

  • the PCV (Positive Crankcase Ventilation) system, or
  • the intake/turbo inlet on diesel and turbo engines.

  This allows the engine to:

  • relieve crankcase pressure
  • reburn emissions
  • keep the engine clean internally

  Common symptoms of a bad blowby hose

  • Oil leaking around the hose
  • Cracked or collapsed hose
  • Excessive smoke or oil vapor
  • Rough idle
  • Check engine light
  • Whistling or hissing noises

  Common locations

  Usually found:

  • between the valve cover and intake
  • near the turbo inlet on diesel engines
  • connected to a PCV valve
