🔌 Function

Drains oil back to the sump under gravity after it has passed through the component it served, keeping the return path clear so pressure cannot build behind it.

⚠️ Common Signs of Failure

• Blue smoke and oil carried into the charge air system where a turbocharger drain is restricted
• Oil forced past a seal that a clear drain would have relieved
• Weeping or staining at a union on the return run
• Pipe found kinked, crushed or coked up internally
• Union faces scored or the flare cracked on removal

🛠️ Service Notes

• Prove the return pipe is clear before condemning a seal or a turbocharger - a restricted return raises pressure behind the seal and pushes oil past it
• Renew the sealing washers at the unions and keep the run falling continuously to the sump
