Valve Cover Gasket (25hp / 36hp) – 111-101-483 The 111-101-483 is an essential maintenance item for owners of "split-window" and early "oval-window" Volkswagens. Because early air-cooled engines rely on a secure seal to maintain internal oil pressure and cooling efficiency, a leaking valve cover gasket can lead to messy engine bays and potential overheating. This gasket is precision-cut to match the unique footprint of the early 25hp and 36hp heads. Unlike later gaskets, these are slightly smaller and have a different profile. They are designed to be used with the original "clip-on" style valve covers and provide the necessary cushion to prevent metal-to-metal contact while sealing the valvetrain area.

OEM Fitment: Matches the original Volkswagen and Porsche factory dimensions for early-style cylinder heads. Leak Prevention: Critical for keeping the pushrod tubes and lower engine area free of oil saturation. Technical Specifications Part Number: 111-101-483 Application: 25hp & 36hp Upright Engines Material: Compressed Cork Unit of Sale: Sold Individually Installation & Maintenance Tips Clean Surfaces: Before installing the new gasket, ensure both the cylinder head and the valve cover surfaces are completely free of old gasket material and oil residue. No Sealer Required: In most cases, these gaskets should be installed "dry." If you have persistent leaks, a very thin smear of high-tack gasket sealant on the cover side only can help keep the gasket in place during installation. Regular Replacement: It is a best practice to replace these gaskets every time you remove the valve covers for a valve adjustment (typically every 3,000 miles). 71-12010-00 111101483R 111101481
