What parts are included and which OEM numbers does it replace?

The package contains one complete engine valve cover gasket set plus the solenoid valve gasket configured to match the original sealing points. The kit serves as a replacement for numerous OEM part numbers, so you can repair leaking valve covers without sourcing multiple separate gaskets.

• Included: 1 x engine valve cover gasket set (with solenoid valve gasket)
• Replaces: VS50773R, VS50559, 12030RJA000, VS50558, 12341R70A00, 12351R70A00, and related numbers
• Check compatibility by cross-referencing year, model, engine code, and OEM part number

How does installing this gasket kit help engine maintenance?

Replacing aged or damaged valve cover and solenoid gaskets restores a tight seal, preventing oil seepage onto the motor and downstream components. That reduces oil loss, keeps ignition coils and spark plug wells cleaner, and preserves PCV/ventilation performance when installed correctly.

• Stops common oil leaks at valve covers and solenoid ports
• Protects ignition components from oil contamination
• Maintains proper crankcase ventilation when gaskets seal correctly

What should I check before buying and installing this kit?

Confirm that the kit matches your vehicle’s engine displacement and model year, and note the Odyssey exclusion for the J35A6 engine. Use your VIN or vehicle configuration in a fitment tool if available, and inspect mating surfaces for warpage or damage before installing new gaskets.

• Verify year, make, model, and engine code against the compatibility list
• Inspect valve cover and head surface for flatness and cleanliness
• Replace any worn fasteners or clips for a reliable seal

Who is this for: This RICHWEI gasket set is aimed at DIY mechanics and professional technicians working on Honda and Acura V6 engines from the late 2000s through mid-2010s who need a comprehensive valve cover and solenoid valve seal replacement. If you’re troubleshooting oil leaks around the valve cover area or performing a scheduled gasket refresh, this kit provides the key components in one matched package—just confirm fitment for your exact engine code before purchase.
