⚠️ Common Signs of Failure

• Oil weeping or misting at a turbocharger union
• Hot-oil smell and light smoke from the turbo area after a run
• Turbocharger noisy or slow to build boost if the oil path restricts
• Line found chafed, kinked or cracked at a support point
• Internal bore found coked and union faces found grooved on strip-down

🛠️ Service Notes

• Only 1 gram separates this from the 0.129 kg return line 20484776, so weight cannot identify it - order by part number
• Blow the line through before fitting and renew the union sealing washers; a restricted oil path will destroy a turbocharger bearing
