🔌 Function

Supplies or returns lubricating oil between the engine oil circuit and the assigned component, maintaining pressure and unrestricted drainage.

⚠️ Common Signs of Failure

• Oil leakage at the pipe or end fittings
• Restricted flow from carbon or debris
• Cracked or work-hardened tubing
• Low oil pressure at the supplied component
• Oil starvation damage to the turbocharger or bearing assembly

🛠️ 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
