The Honda 12391-ZG5-000 Head Cover Gasket is a genuine OEM component designed for the EB12 generator. As a direct Honda replacement, this gasket is manufactured to the same specifications as the original, ensuring a proper seal between the head cover and the engine. Verify your unit's serial number against the fitment table to confirm this is the correct gasket for your EB12 before ordering.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to deliver the same compression and oil retention performance as the original gasket, with no guesswork on material grade or clamping retention
- Direct OEM Replacement — engineered to match the original head cover interface on the EB12 generator for a straightforward, by-the-book installation
- Serial Number Verification Recommended — Honda updates parts at production breaks, so confirm your EB12 serial number against the fitment table to ensure part number 12391-ZG5-000 is the right specification for your unit
- Protect Engine Oil Integrity — a failed or degraded head cover gasket allows oil to escape and contaminants to enter; replacing it promptly keeps the engine running cleanly and prevents oil loss damage
The head cover gasket forms a seal between the valve or head cover and the top of the engine, preventing oil from leaking out around the cover and keeping debris from entering the valvetrain area. Over time, heat cycling causes gasket material to compress and harden, leading to oil seepage that can foul the generator and create a fire hazard if left unaddressed. Replacing a worn or cracked head cover gasket restores a clean, oil-tight seal and is a routine part of keeping the EB12 generator in sound working condition.
