Detailed Fitment and Use

Use the Apex AVC425S when servicing a leaking or hardened valve cover seal on supported Ford Ranger, Ford Taurus, and Mercury Sable engines, as well as select Mazda B3000, Ford Windstar, Ford Aerostar, Ford Tempo, Mercury Topaz, and Ford Probe applications. The AVC425S part number is a practical search reference for buyers looking for an engine valve cover gasket set for these specific vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Oil seepage around the valve cover perimeter
• Oil residue on the engine exterior
• Burning-oil odor from leaks contacting hot engine surfaces
• Moisture or debris entering a compromised valve cover seal area
• Maintenance replacement after gasket hardening or compression loss

Installation Notes

Clean the sealing surfaces thoroughly before installation and inspect the valve cover for warpage, cracks, or damaged gasket grooves. Verify the vehicle application by year, make, model, and notes, especially for the 1991 Ford Aerostar engine-code-specific listing. The AVC425S is listed for vehicles with grommets, so confirm the existing setup matches the fitment notes before ordering.

Quality Assurance

Apex identifies this as an engine sealing component for the listed applications. Confirm fitment against the vehicle’s year, make, model, and engine notes to ensure the correct seal for your repair.
