⚙️ Key Features

• 0.129 kg
• For the turbocharger lubricating-oil feed and return system
• Listed for 2 applications on TAD series engines
• Close in weight to the 0.128 kg oil line 20500644 in the same system

🔌 Function

Returns oil from the turbocharger bearing housing to the crankcase, keeping the drain route clear and correctly supported.

⚠️ Common Signs of Failure

• Blue smoke and oil in the exhaust as the drain restricts
• Oil weeping at the drain union or along the line
• Oily film building up across the turbocharger and manifold
• Line found coked internally or chafed at a support on strip-down

🛠️ Service Notes

• Only 1 gram separates this from the 0.128 kg oil line 20500644, so weight cannot identify it - order by part number
• Confirm the drain is clear before condemning the turbocharger; a restricted return pushes oil past the bearing seals
