🔌 Function

Seals the turbocharger oil-line connection, crushing slightly as the union is tightened to fill the surface irregularities between the fitting and its seat so pressurised oil is contained at the joint.

⚠️ Common Signs of Failure

• Oil weeping or dripping from the turbocharger feed or drain union
• Oil smell and smoke from oil landing on the hot turbo housing or exhaust
• Oil level falling with no external leak found elsewhere on the engine
• Washer found flattened, hard, or bonded to the fitting on removal
• Scored or pitted sealing face beneath the washer, so a fresh one will not seal either

🛠️ Service Notes

• Confirm thread, length, grade and any single-use restriction against the exact application
• Clean the threads and use the specified torque, angle and locking method
