🔌 Function

Carries air or crankcase vapour through the assigned engine circuit while maintaining a sealed, unrestricted path.

⚠️ Common Signs of Failure

• Oily mist or an air leak audible around the breather and inlet run
• Hose gone soft, spongy or ballooned where oil vapour has swollen the rubber
• Cracking at the moulded bends and at the ends where the clamps grip
• Hose end split or cut through by an over-tightened clamp
• Inner wall collapsed or delaminated, found only when the hose is cut open

🛠️ Service Notes

• Check the hose ends and clamp positions before condemning the hose - most leaks in this run are at the joint rather than the middle
• Renew the hose if oil has swollen it, as a swollen hose will not seal on a clean spigot
