⚙️ Key Features

• For the turbocharger lubricating-oil feed and return system
• Listed for 1 application on TAD series engines
• Close in weight to the 0.202 kg oil pipe 20476142 in the same system

🔌 Function

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

⚠️ Common Signs of Failure

• Oil in the exhaust and blue smoke as a restricted drain backs oil up past the turbo seals
• Oil weeping from the drain union or from the pipe body
• Oily film across the turbocharger and manifold area
• Pipe found part-blocked with carbon and sludge on strip-down
• Pipe found chafed or crushed where it passes a bracket

🛠️ Service Notes

• A blocked or kinked return is a common cause of oil being pushed past turbo seals - check the drain is clear rather than condemning the turbocharger
• The 0.202 kg pipe 20476142 is only 14 grams different, so order by part number, and renew the union washers on refitting
