The Honda 12311-Z2E-010 Cylinder Head Cover is a genuine OEM Cylinder Head Cover designed for GX440 horizontal shaft engines. As a direct Honda OEM component, this part is manufactured to the same specification as the original, ensuring a proper fit without modification. Sourced directly from Honda's parts catalog, it is the correct replacement when the original cover is cracked, warped, or leaking oil. Confirm your unit's serial number against the fitment table before ordering to ensure part number 12311-Z2E-010 is the right match for your engine's production range.
Key Features
- Genuine Honda OEM Construction — manufactured to the same specification as the original, with correct sealing geometry to prevent oil leaks at the valve train enclosure.
- Built for GX440 Engines — engineered specifically for GX440 horizontal shaft engines; no fitting, trimming, or adapting required for a proper installation.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so check your engine's serial number against the fitment table to confirm this is the correct cover for your unit.
- Restores Valve Train Protection — a damaged or leaking cylinder head cover exposes the valve train to contamination and allows oil to escape, leading to accelerated wear and potential engine damage.
The cylinder head cover seals the top of the engine's cylinder head, enclosing the valve train — the rocker arms, valves, and associated components — and keeping engine oil contained within the lubrication circuit. When the cover cracks, warps, or its gasket fails, oil can escape onto hot engine surfaces and contaminants can enter the valve chamber, shortening the service life of internal components and creating a fire hazard from oil contacting exhaust components.
