These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O-Ring seals use the standard retainer and oil splash shield. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop PTFE seal is used. We also have a smaller diameter Viton seal available for triple spring applications. Both the O-Ring and the umbrella seals require no machining, but with the PTFE seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don't forget the valve seals.\u003c\/p\u003e\u003cp\u003eFor 4 Cylinder use -8 suffix, for 6 Cylinder use -12 suffix.\u003c\/p\u003e","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":45480960163897,"sku":"04MBJ","price":53.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/8632\/8889\/files\/f4485d0292a5aca0254f02e6503f3a81.jpg?v=1771390018","url":"https:\/\/shop.throttletherapynation.com\/products\/comp-cams-11-32-530-metal-jacket-viton-valve-seal-1","provider":"Throttle Therapy Nation ","version":"1.0","type":"link"}
