The Honda OEM Engine Oil Filler Cap Gasket is a genuine factory replacement designed to provide a reliable seal between the engine oil filler cap and the valve cover. Manufactured to Honda's original equipment specifications, this replacement gasket helps prevent oil seepage, maintain a clean engine bay, and ensure a secure seal around the engine oil filler opening.

Also known as an oil filler cap O-ring, oil cap seal, or oil filler cap packing, this genuine Honda gasket is compatible with a wide variety of Honda and Acura engines, including select B-Series, D-Series, F-Series, H-Series, K-Series, and other factory engine applications.

Over time, the original oil filler cap gasket can become hardened, flattened, cracked, or damaged due to repeated exposure to engine heat and oil. A deteriorated gasket may allow oil residue to accumulate around the filler cap, resulting in unwanted oil seepage and a messy valve cover.

Replacing the worn gasket with a genuine Honda OEM component is an inexpensive and effective way to restore proper sealing without purchasing an entirely new oil filler cap.

Whether you're performing routine engine maintenance, restoring a classic Honda, rebuilding a K20/K24 engine, or refreshing your engine bay, this genuine Honda OEM Oil Filler Cap Gasket provides dependable factory-style sealing performance.

Common Reasons for Replacement

Oil filler cap gaskets are exposed to engine heat, oil, and repeated removal during routine maintenance.

• Oil seepage around the engine oil filler cap
• Oil residue accumulating on the valve cover
• Hardened or brittle original gasket
• Flattened or compressed sealing surface
• Cracked, torn, or damaged gasket
• Missing oil filler cap seal
• Oil filler cap maintenance
• High-mileage engine restoration

• Engine rebuilding or maintenance
• Restoring a clean engine bay
• Replacing a worn oil filler cap gasket helps restore proper sealing and prevents unnecessary oil residue around the filler opening.

Installation Notes

• Installation is straightforward and typically requires no special tools.
• Allow the engine to cool before removing the oil filler cap.
• Remove the oil filler cap from the valve cover.
• Carefully remove the original gasket from the underside of the cap.
• Clean the gasket groove and inspect the oil filler cap for cracks or damage.
• Install the new Honda OEM gasket into the original sealing groove.
• Make sure the gasket is seated evenly and is not twisted or pinched.
• Reinstall the oil filler cap and tighten it securely by hand.
• Inspect the area for oil seepage after the engine has been operated.
• Important: Do not use sharp tools that could damage the oil filler cap or its sealing surface. If the cap itself is cracked, distorted, or damaged, replacing the gasket alone may not correct the leak.
