🔌 Function

Supplies clean pressurised engine oil to the turbocharger bearing housing for lubrication and heat removal.

⚠️ Common Signs of Failure

• Oil leakage at line fittings or cracked pipe
• Turbocharger whine, bearing wear or seizure from restricted oil supply
• Blue smoke or turbo oil leakage
• Coking inside the line after overheating
• Damaged sealing ring or distorted connection
• Low oil flow caused by blocked inhibitor/non-return valve

🛠️ 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
