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).

Oil Separator. One of the most common failures in the Boxster or 996 is the Air/Oil Separator, also referred to as the AOS.

Oil Separator. One of the most common failures in the Boxster or 996 is the Air/Oil Separator, also referred to as the AOS.
The AOS is basically a small diaphragm distillery which distills the minute amounts of oil mist in the crankcase, liquifies it and sends it back to the crankcase. The "clean" air is now sent into the air intake (after the throttle body) to be burned off by the engine.
When the AOS starts to fail it cannot separate all of the oil out of the mist and some liquid oil is sent to the air intake.
A few drops of oil is enough to generate the GREAT SMOKE BOMB for which our cars are famous for.
A big smoke bomb once in a while is completely normal, due to the architecture of the flat-6 engine, which may let a drop of oil flow into one of the combustion chambers sporadically.
