🔌 Function

Seals the oil filler cap to the filler neck while allowing the cap to be removed for engine-oil servicing.

⚠️ Common Signs of Failure

• Oil mist or wetness around the filler cap
• Dust entering around the cap
• Seal flattened, cracked or swollen
• Cap no longer tightening securely
• Oil odour or staining on the valve cover

🛠️ Service Notes

• Sits beneath oil filler cap 20807510 specifically — confirm the cap fitted to your engine before ordering, as this seal is sized to that cap rather than a generic filler neck
• Approximate aftermarket dimensions are 39.67 mm inside diameter with a 5.53 mm section — check a removed seal against these before assuming a different rubber washer in the range will substitute
• Renew if flattened, hard or swollen rather than reusing; EPDM seals harden with age and heat around the filler neck
