The Turner Motorsport Polished Valve Cover Cap Nut serves as a direct replacement designed to address these common failure points while improving upon overall engine bay aesthetics. \u003c\/p\u003e\n\u003cp\u003eBecause maintaining precise gasket compression is critical to preventing oil leaks, these cap nuts and washers are machined directly to OE-style dimensions. This exact fitment allows for direct compatibility with original and replacement valve cover studs (see ES#5434624) and ensures the hardware can be torqued precisely to OEM specifications without guesswork. Manufactured to grade 8.8 structural strength standards, the hardware maintains the necessary clamp force required under normal and high-performance engine operating conditions.\u003c\/p\u003e\n\u003cp\u003eTo resist corrosion, both the cap nut and washer undergo an electroless nickel plating process during production. Unlike standard zinc coatings that dull or rust over time, electroless nickel provides a uniform layer of corrosion resistance that withstands long-term chemical exposure and extreme temperature swings while giving the hardware a polished, high-end appearance. Each cap nut assembly includes an OE rubber washer seal, ensuring a tight, leak-free barrier that prevents oil from escaping through the mounting studs.\u003c\/p\u003e\n\u003cp\u003eFEATURES\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cp\u003eMachined to exact factory specifications for a direct drop-in fit that retains standard torque values and clamping force.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eGrade 8.8 hardware engineered to meet strict structural strength standards to prevent thread stripping and maintain reliable tension.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eElectroless nickel plating delivers superior protection against rust, oil, and chemical corrosion in high-heat environments.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eBright finish provides a clean, refined look ideal for engine bay restorations and detailed builds.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Turner Motorsports","offers":[{"title":"Default Title","offer_id":67790161903920,"sku":"5480678","price":7.14,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7582\/4176\/files\/2102632_x800_5e2985fb-084d-4f11-9929-91376d7f22ec.jpg?v=1789509874","url":"https:\/\/es-performance.com\/products\/turner-motorsport-polished-valve-cover-cap-nut-11121738607-priced-each","provider":"Eurosport Performance","version":"1.0","type":"link"}
