21139074 Oil Line | Genuine Volvo Penta Part

🔧 Product Description

Brand-new genuine Volvo Penta alternate turbocharger lubrication line for D11A engine configurations using the corresponding turbocharger and exhaust arrangement. Its bends and connection geometry are specific to the revised turbo location and must not be substituted with the other D11 oil lines.

⚙️ Key Features

• Rated for hot pressurised engine oil
• Rigid routing reduces hose expansion and abrasion
• Line only; sealing rings and hollow screws are separate
• Engine type: Volvo Penta D11 inline six-cylinder marine diesel

🔌 Function

Transfers lubricating oil to or from the turbocharger while preserving the specified flow, drainage angle and sealing integrity.

⚠️ Common Signs of Failure

• Oil leakage at the turbocharger connection
• Restricted oil flow and turbo bearing noise
• Blue exhaust smoke after bearing damage
• Vibration crack or heat damage to the line
• Oil starvation or coking in the turbo bearing housing

🛠️ 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
