20708833 Oil Line | Genuine Volvo Penta Part

🔧 Product Description

A genuine pressurised turbocharger oil line used in the TAD520VE inlet and exhaust system. It carries engine oil through the documented banjo and clamp arrangement to the turbocharger bearing housing.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD520VE

• Engine Family: TAD

⚙️ Key Features

• Factory-formed routing for the TAD520VE turbocharger installation
• Designed for hot pressurised engine oil
• Banjo/hollow-screw connection uses gasket 969011 and screw 25167
• Retainer and clamp points reduce vibration fatigue
• Must remain clear of exhaust heat and moving components
• Verify unrestricted flow and prime the turbocharger after installation

🔌 Function

Delivers pressurised lubricating oil to the turbocharger bearings.

⚠️ Common Signs of Failure

• Oil leaks from the pipe or banjo fittings
• The turbocharger is starved of oil
• The line is kinked, cracked, carboned or heat-damaged
• Clamps or retaining points are loose
• Turbo bearing noise or failure follows restricted flow

🛠️ Service Notes

• Work clean and cap or plug both the line and its ports as soon as they are open — anything that gets into an oil line ends up at a bearing or in the turbocharger
• Renew the sealing washers, O-rings or gaskets at each end rather than reusing them, and start unions by hand so the seal is not loaded sideways
• Do not bend or reshape a line to make it reach; a line strained into place fatigues and cracks at the union
• Refit every clip and support bracket in its original position — an unsupported oil line chafes and fails through vibration
• After fitting, check oil level, run the engine and check the unions for leaks and the oil pressure for normal reading, then check again once hot
