⚠️ Common Signs of Failure

• Oil mist or leakage at joints
• Blocked pipe causing positive crankcase pressure
• Cracking from heat and vibration
• Oil consumption associated with ventilation faults
• Whistling, suction or unstable crankcase pressure

🛠️ Service Notes

• Route the new pipe exactly as the original ran, with no kinks and no sagging low point where oil or condensate can collect and block the flow
• Support the pipe with its original clips and keep it clear of hot surfaces and moving parts; a chafed or melted breather puts oil mist into the engine space
• Make sure both connections are clean, sealed and clamped — a leaking breather makes an oily mess and upsets crankcase pressure
• Clean out the breather housing, hose stub or oil separator while the pipe is off; blocked crankcase ventilation pressurises the crankcase and pushes oil past seals and the dipstick
• Check the joints again after the first run at temperature, when the pipe is soft and connections can settle
