Engine Crankcase Breather Hose Kit
The engine crankcase breather hose is a key part of your vehicle’s positive crankcase ventilation (PCV) system. Its main role is to route pressurized gases from the engine crankcase to the PCV valve (also called the air/oil separator). The PCV valve captures harmful oil vapers , drains them back into the engine, and redirects the cleaned air to the intake system to be burned during normal combustion.
Without a properly functioning breather hose, your engine can develop performance issues, oil leaks, and even emissions failures.
Fits:
Porsche 957 Cayenne S / GTS 4.8L 2009 - 2010
Why the Engine Crankcase Breather Hose Matters
During combustion, engines naturally produce positive crankcase pressure. This pressure combines with heat and oil vapers inside the crankcase. The breather hose is designed to handle this flow and keep your PCV system working efficiently.
Over time, however, exposure to heat, oil, and pressure makes the breather hose a common failure point. When damaged, it can cause poor performance, check engine lights, and increased emissions.
Common Symptoms of a Failing Crankcase Breather Hose
- Cracks, leaks, or breaks – Heat and oil vapers degrade rubber or plastic over time, leading to air leaks.
- Broken connectors or clips – Brittle plastic can snap during service or due to age.
- Visible damage – Hoses may split, soften, or harden, creating noticeable holes.
- Check Engine Light (CEL) – Unmetered air from a leak often triggers intake-related fault codes.
- Engine misfires or rough idle – Severe air leaks upset the air/fuel mixture, causing misfires.
Oil residue or odour – Escaping vapers leave oily deposits on the hose, engine block, and nearby components. In severe cases, you may smell burning oil.
Why You Shouldn’t Ignore a Bad Breather Hose
A faulty crankcase breather hose affects engine performance, fuel efficiency, and emissions compliance. Left untreated, it can cause long-term engine damage and costly repairs.
If you notice any of the above signs, it’s important to inspect and replace your crankcase breather hose as part of regular PCV system maintenance.

The Vent Breather Pipe is a OE MATCH component designed for the engine’s crankcase ventilation (PCV) system. This breather pipe routes crankcase vapours and excess pressure from the engine to the air/oil separator or intake system, helping maintain proper internal engine pressure and emissions control. It ensures correct fitment, reliable sealing, and long-term durability on Porsche 957 Cayenne S / GTS 4.8L models.
Fits:

Diagram Ref No 10 (Diagram Ref No 11 And 12 Included)
What This Product Does:
- Vents excess crankcase pressure created during engine operation.
- Routes blow-by gases and oil vapours to the PCV/air-oil separator system for proper ventilation.
- Helps reduce stress on engine seals and gaskets by preventing pressure build-up.
- Supports proper emissions control by returning vapours into the intake system rather than releasing them.
Symptoms Of Wear Or Failure:
- Cracks or splits in the breather pipe can cause a vacuum leak, leading to rough running or unstable idle.
- A leaking breather pipe can trigger engine management faults related to vacuum system leaks, PCV system performance, air/fuel mixture imbalance.
- If crankcase pressure is not vented correctly, it can push oil past seals and gaskets, causing leaks.
- Oil vapours escaping from a damaged breather pipe may cause an oily smell in the engine bay.
- Symptoms may include oil filler cap difficult to remove, whistling/hissing noises, pressure-related seal issues.
- Breather pipes often fail due to age and heat, showing hardened plastic/rubber, cracking, broken fittings or connectors.
- If ventilation is disrupted, oil vapour can be drawn into the intake incorrectly, contributing to oil burning.
Why Replacement Matters:
- Prevents vacuum leaks, which can cause rough idle, poor performance, and fault codes.
- Maintains proper crankcase ventilation, preventing pressure build-up inside the engine.
- Helps prevent oil leaks, since excessive crankcase pressure can force oil past seals and gaskets.
- Protects engine performance and efficiency, by keeping the air/fuel mixture stable and reducing unmetered air entering the system.
- Reduces risk of secondary damage, such as damaged seals, intake contamination, or long-term PCV system issues.
