{"product_id":"bmw-crankcase-vent-hose-13","title":"Original BMW Cylinder 1–4 Bank PCV-to-Intake Vent Pipe, N63 V8, for BMW 550i, 650i, 750i, Alpina B7, X5, and X6 (2008–2014)","description":"\u003cp\u003eOn the N63 twin-turbo V8, this Original BMW vent pipe carries crankcase vapors from the PCV valve on the cylinder 1–4 bank to the intake manifold in the 550i, 650i, 750i, Alpina B7, X5 xDrive50i, and X6. Blow-by gases that slip past the piston rings build pressure in the crankcase, and the crankcase ventilation system routes them back into the intake to be burned. That process manages crankcase pressure and helps control emissions. BMW names this part the vent pipe for cylinders 1–4. It weighs 50 g (0.1 lb), comes as a single piece, and is made in the Czech Republic. Production started in July 2008.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts like this vent pipe carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eThe N63 runs separate ventilation hardware for each cylinder bank, and this number covers only the 1–4 side. The number 11-15-8-645-238 cross-references to this pipe. BMW's parts data spans the F07 5 Series Gran Turismo, F10 and F11 5 Series, F12 and F13 6 Series, F01, F02, F03, and F04 7 Series, E70 facelift X5, and E71 and E72 X6. Heat, pressure, and oil vapor make this hose a common failure point. The plastic grows brittle with age, and its connectors can break during removal or nearby service work.\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: 11-15-7-575-640\u003c\/li\u003e\n\u003cli\u003eBMW part name: vent pipe, cylinders 1–4\u003c\/li\u003e\n\u003cli\u003eCross-reference: 11-15-8-645-238\u003c\/li\u003e\n\u003cli\u003eEngine: N63 V8\u003c\/li\u003e\n\u003cli\u003eWeight: 50 g (0.1 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: July 2008\u003c\/li\u003e\n\u003cli\u003eMade in the Czech Republic\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months on parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms point to a failed vent pipe?\u003c\/strong\u003e\u003cbr\u003eCracks, splits, or broken connectors let unmetered air in.
