{"product_id":"bmw-valve-cover-23","title":"Original BMW Valve Cover for BMW 535d, 535d xDrive, and X5 xDrive35d (2014–2018)","description":"\u003cp\u003eOriginal BMW valve cover 11-12-8-578-811 is the cylinder head cover for the N57N engine in the BMW 535d, 535d xDrive, and X5 xDrive35d, closing off the valvetrain at the top of the cylinder head. Every valve cover has the same basic job. It keeps the oil that lubricates the valves and valvetrain inside the head and keeps dirt and debris away from those parts. This one weighs 2 kg (4.4 lb), is made in Germany, and comes as a single cover.\u003c\/p\u003e\u003cp\u003eThis Original BMW Part carries a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eBMW calls this part a cylinder head cover, while most shops and parts counters know it as a valve cover or rocker cover. All three names describe the same piece. One part number spans two quite different vehicles here. BMW fits this cover to the N57N in the facelifted F10 5 Series, sold as the 535d and 535d xDrive, and to the N57N in the F15 X5 xDrive35d. The engine ties the application together rather than the body, so the X5 and 5 Series owners in the fitment order exactly the same part.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW part)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-12-8-578-811\u003c\/li\u003e\n\u003cli\u003eBMW part name: Cylinder head cover\u003c\/li\u003e\n\u003cli\u003eEngine: N57N\u003c\/li\u003e\n\u003cli\u003eChassis: F10 Facelift 5 Series and F15 X5\u003c\/li\u003e\n\u003cli\u003eWeight: 2 kg (4.4 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: July 2013\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Germany\u003c\/li\u003e\n\u003cli\u003eSold as: single cover\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on Original BMW Parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat causes a valve cover to leak or fail?\u003c\/strong\u003e\u003cbr\u003eGaskets harden and crack with age, and uneven torque or a poorly placed gasket at installation also causes leaks. High engine temperatures can warp or crack the cover itself, and a blocked PCV valve can build crankcase pressure that damages it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this cover fit a 2013 535d?\u003c\/strong\u003e\u003cbr\u003eThe fitment for this part starts with the 2014 model year, and BMW applies it only to facelift F10 production, so a pre-facelift 535d falls outside it.
