🔌 Function

The washer seals the injector where it enters the cylinder head, containing combustion pressure and gases at the nozzle seat. It also provides a consistent crush surface so the injector clamps down to the correct seated height.

⚠️ Common Signs of Failure

• Combustion gas or soot leakage tracking around the base of the injector
• Loss of compression or rough running on the affected cylinder
• Hard starting or uneven idle after injector service
• Flattened, cracked or previously crushed washer found on removal
• Injector difficult to seat correctly or loosening in service

🛠️ Service Notes

• Renew this washer every time the injector is removed — it is a crush washer and must not be reused.
• Fit in the correct stack order with the matching heat shield and waved washer for the engine; these are separate parts and must not be substituted for one another.
• Confirm quantity before ordering: 4 required for a complete 30-series engine, 6 for a complete 40-series engine.
