🔌 Function

Carries the lubricating oil leaving the turbocharger bearing housing back down to the engine, letting it drain away freely so that oil does not back up in the centre housing.

⚠️ Common Signs of Failure

• Reduced boost pressure, power loss or slow acceleration
• Black exhaust smoke or elevated exhaust temperature
• Excessive shaft movement or damaged compressor/turbine blades

🛠️ Service Notes

• Check the drain is clear and undistorted before condemning a turbocharger for oil leakage - a restricted or kinked drain backs oil up in the bearing housing and pushes it past the seals
• If the turbocharger has failed, clean or renew the drain as well, since debris and coked oil left in the line will reach the replacement
