🔌 Function

Returns oil from the turbocharger bearing housing to the crankcase along the drain path the installation provides.

⚠️ Common Signs of Failure

• Blue smoke and oil in the exhaust as the drain restricts
• Oil weeping at the drain union or along the pipe
• Oily film building on the turbocharger and manifold
• Pipe found coked internally or chafed externally on strip-down
• Flange or union faces found distorted

🛠️ Service Notes

• Confirm the drain is fully clear and the pipe unkinked - restricted turbo drainage forces oil past the bearing seals
• Renew the joint gasket or washers at the union and check the pipe is supported clear of hot surfaces
