Factory BMW dealerships do not offer internal PCV components individually, requiring vehicle owners to purchase a complete, expensive valve cover assembly when the internal rubber membrane ruptures. This repair kit provides a direct replacement cap, diaphragm, and tension spring to service the valve cap without replacing the entire valve cover.\u003c\/p\u003e\n\u003cp\u003eProlonged thermal cycling causes the factory rubber PCV diaphragm to crack or tear, resulting in unmetered air leaks, excessive crankcase vacuum, high oil consumption, and severe tailpipe smoking. Replacing the internal membrane restores proper crankcase pressure regulation and air-fuel mixture stability.\u003c\/p\u003e\n\u003cdiv class=\"attachment-container search-images\"\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cb\u003eVehicle Compatibility:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eDirect-fit replacement kit engineered exclusively for \u003cb\u003eGen 1 B58 3.0L Turbocharged Inline-6 Engines\u003c\/b\u003e across the following BMW platforms:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 1 Series (F20 \/ F21 Euro):\u003c\/b\u003e 2016–2019 (M140i, M140i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 2 Series (F22 \/ F23):\u003c\/b\u003e 2017–2021 (M240i, M240i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 3 Series (F30 \/ F31 \/ F34 GT):\u003c\/b\u003e 2016–2019 (340i, 340i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 4 Series (F32 \/ F33 \/ F36 Gran Coupé):\u003c\/b\u003e 2017–2020 (440i, 440i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 5 Series (G30):\u003c\/b\u003e 2017–2019 (540i, 540i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW 7 Series (G11 \/ G12):\u003c\/b\u003e 2016–2019 (740i, 740iL, 740i xDrive)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eBMW X3 \u0026amp;
