Manufactured from high-grade composite plastic, this cover is responsible for sealing the top of the cylinder head, protecting the Valvetronic system, and housing the high-pressure fuel injectors.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eA critical engineering feature of this cover is the \u003cb data-path-to-node=\"2\" data-index-in-node=\"52\"\u003eIntegrated Positive Crankcase Ventilation (PCV)\u003c\/b\u003e system. In the N55 engine, the PCV diaphragm is prone to tearing over time, leading to significant vacuum leaks, high oil consumption, and a distinct \"squealing\" or \"whistling\" sound at idle. Because the PCV valve is heat-welded into the plastic housing, the entire valve cover must be replaced to resolve these issues. Additionally, the plastic is known to warp or crack near the rear of the engine (cylinders 5 and 6) due to heat soak, resulting in oil leaking onto the hot exhaust manifold and causing a burning smell in the cabin. This replacement kit typically includes the pre-installed perimeter gasket and the spark plug tube seals.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eVehicle Compatibility:\u003c\/b\u003e This valve cover is designed for the \u003cb data-path-to-node=\"3\" data-index-in-node=\"60\"\u003eN55 (Single-Turbo, Twin-Scroll)\u003c\/b\u003e inline-6 engine:\u003c\/p\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003e3 Series Sedan (F30):\u003c\/b\u003e 2012–2015 (335i, 335ix)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003e3 Series Coupe\/Vert (E92 \/ E93):\u003c\/b\u003e 2011–2013 (335i)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003e5 Series Sedan (F10):\u003c\/b\u003e 2011–2016 (535i, 535ix, Hybrid 5)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003e1 Series (E82 \/ E88 \/ F20):\u003c\/b\u003e 2011–2015 (135i, M135i)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,4,0\"\u003e\u003cb data-path-to-node=\"4,4,0\" data-index-in-node=\"0\"\u003e4 Series (F32 \/ F33 \/ F36):\u003c\/b\u003e 2014–2016 (435i, 435ix)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,5,0\"\u003e\u003cb data-path-to-node=\"4,5,0\" data-index-in-node=\"0\"\u003eX3 (F25):\u003c\/b\u003e 2011–2017 (xDrive35i)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,6,0\"\u003e\u003cb data-path-to-node=\"4,6,0\" data-index-in-node=\"0\"\u003eX5 (E70 \/ F15):\u003c\/b\u003e 2011–2018 (35i, 35ix)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,7,0\"\u003e\u003cb data-path-to-node=\"4,7,0\" data-index-in-node=\"0\"\u003eX6 (E71 \/ F16):\u003c\/b\u003e 2011–2019 (35i, 35ix)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eMaterial:\u003c\/b\u003e Reinforced Composite Plastic\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eIncludes:\u003c\/b\u003e Valve Cover Gasket, Spark Plug Seals, Perimeter Bolts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eEngine Code:\u003c\/b\u003e N55B30A\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":48196759027951,"sku":"11127570292","price":2850.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/7183\/5631\/files\/2013-F30-335i-N55-Valve-Cover.png?v=1774444514","url":"https:\/\/myty.co.za\/products\/engine-valve-cover-bmw-1-2-3-4-5-7-series-x3-x5-x6-11-19","provider":"MYTY Auto Parts","version":"1.0","type":"link"}
