Detailed Description

Use the Apex AVC604S when servicing valve cover sealing on covered Subaru Impreza and Subaru Legacy models. This gasket set is listed for vehicles with grommets and is cataloged for specific production cutoffs, including 1998 Subaru Impreza built to 06/30/98 and 1998 Subaru Legacy built to 05/31/98. The AVC604S is a practical choice for replacing worn valve cover sealing components on Subaru engines where oil control at the cover is a concern.

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

What It Helps Address

• Oil seepage around the valve cover sealing surface
• Visible gasket deterioration from age and heat cycling
• Leaks after valve cover service on Subaru engines
• Loss of sealing integrity at the cover-to-head interface

Installation Notes and Tips

Confirm engine build date before ordering, since the 1998 Subaru Impreza and 1998 Subaru Legacy applications are limited by production cutoff. Clean the mating surfaces thoroughly before installation and inspect the valve cover for warpage or damage that could affect sealing. Verify that the application uses grommets, as listed in the fitment notes.

Quality Assurance

Apex identifies this part as an engine sealing component for the listed Subaru applications. Verify fitment against the vehicle’s year, model, and production date before installation.
