20714027 Breather Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine crankcase breather pipe used in the TAD722VE inlet and exhaust system. It routes crankcase vapour between the engine, oil separator and inlet/ventilation components.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD722VE

• Engine Family: TAD

⚙️ Key Features

• Confirmed for the TAD722VE crankcase-ventilation assembly
• Factory-formed routing clears the inlet and exhaust hardware
• End connections match the documented hose, clamp and oil-separator components
• Maintains controlled crankcase breathing without unrestricted oil mist discharge
• Correct routing prevents kinks and contact damage
• Inspect the oil separator and connected hoses when replacing the pipe

🔌 Function

Routes crankcase gases through the oil-separation and ventilation system.

⚠️ Common Signs of Failure

• Oil mist or vapour leaks from the pipe
• The pipe is cracked, blocked or collapsed
• Crankcase pressure rises
• Oil leaks develop at connected seals and hoses
• The pipe rubs or loses its specified routing

🛠️ 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
