What This Product Does:
- The crankcase ventilation hose provides a path for filtered crankcase gases (blow-by, vapours, oil mist) to be routed from the engine’s crankcase or oil separator back into the intake or PCV (positive crankcase ventilation) system rather than being vented uncontrolled.
- It helps maintain correct engine vacuum/pressure balance within the crankcase, removes oil vapours, prevents buildup of excess pressure that could cause leaks or gasket failures, and supports emissions compliance.
Symptoms Of Wear Or Failure:
- Visible cracks, splits or brittleness in the hose; rubber/engine bay hoses degrade under heat/oil/vapour over time.
- Oil residue, grime or wetness around the hose or its connectors — if vapour is leaking, you may see oil-moisture deposit around the breather circuit.
- Mis-fires, rough idle or engine running poorly — because un-metered air (via a damaged breather hose) may be introduced, altering the air/fuel ratio.
- Check Engine Light (CEL) or fault codes concerning intake air leak, crankcase pressure or PCV system faults.
- Oil smells in the engine bay / smoke from the breather area — indicating the hose may no longer be securing the vapours correctly.
- Protects engine internals & seals: Proper ventilation prevents excessive crankcase pressure which can force oil past seals or gaskets, causing leaks or damage.
- Maintains performance & emissions: A damaged breather hose can upset engine vacuum and air-fuel mixture, affecting power, idle quality and emissions.
- Prevents bigger failures: A failing hose is inexpensive; ignoring it could lead to more costly repairs (seal replacement, engine bay oil contamination, intake system clean-up).
