Key Features

• Genuine OEM Valve Train Sealing: — Manufactured to the original Honda engine seal specification, ensuring the correct elastomer compound and interference fit for long-lasting valve stem protection.
• Cross-Equipment Compatibility: — A single OEM seal that fits Honda-engined equipment across Multiquip plate compactors (MVH series), walk-behind and ride-on rollers (MRH800GS, V305EH, AR13H), mixers, generators, pumps, and saws.
• Drop-In Installation: — Engineered to the same dimensions as the original part, seating correctly onto the valve stem guide without modification to the cylinder head.
• Prevents Oil Consumption and Smoke: — A functioning valve stem seal meters the correct amount of lubricating oil to the valve stem; a worn seal allows excess oil to burn in the combustion chamber, causing blue smoke and elevated oil consumption.
• Fuel System and Emissions Compliance: — Maintaining an intact valve stem seal keeps combustion clean and helps the engine run within its intended emissions and performance parameters.

A valve stem seal sits at the top of each intake and exhaust valve guide in the cylinder head, controlling how much oil reaches the valve stem to keep it lubricated without allowing excess oil into the combustion chamber. When the seal hardens, cracks, or wears out, oil migrates past the valve stem and burns during combustion — resulting in blue exhaust smoke, fouled spark plugs, increased oil consumption, and eventually reduced engine compression. Replacing a failed valve stem seal with a correctly spec'd OEM part restores proper valve train lubrication balance and returns the engine to clean, efficient operation.
