Diagram Ref No 12

This breather hose forms a vital connection within the engine's crankcase ventilation system, allowing oil vapours and excess pressure to be safely routed away from the engine. The cloth-covered construction helps maintain an authentic factory-correct appearance, making it ideal for both maintenance and restoration projects.  

What This Product Does:

• Connects key components within the engine breather and oil ventilation system.
• Allows crankcase gases and oil vapours to circulate correctly.
• Helps regulate internal engine pressure.
• Supports efficient engine operation and oil system performance.
• Reduces the risk of oil leaks caused by excessive crankcase pressure.

Symptoms Of Wear Or Failure:

• Cracks, splits or perished rubber.
• Oil leaks or oil residue around the hose and connections.
• Strong oil vapour smells from the engine bay.
• Hardened, brittle or collapsed hose sections.
• Excessive crankcase pressure.
• Increased oil mist contamination within the engine compartment.
• Poor engine breathing and ventilation performance.

Why Replacement Matters:

• Breather hoses are constantly exposed to engine heat, oil vapours, pressure fluctuations and vibration. Over time, the rubber can harden, crack or deteriorate, compromising the integrity of the ventilation system. A damaged breather hose can lead to oil leaks, pressure build-up, contamination of engine components and increased wear on seals and gaskets.
• Replacing a worn breather hose helps maintain correct crankcase ventilation, prevents unnecessary oil leaks, protects surrounding engine components and ensures the engine's oil system continues to operate as intended. Regular replacement is an important part of maintaining reliability and preserving the performance of your classic Porsche.
