{"product_id":"bmw-crankcase-vent-hose-12","title":"Original BMW Crankcase Breather Hose, Cylinders 1-4, for BMW 550i, 650i, 750i, X5, and X6 (2008–2014)","description":"\u003cp\u003eThis Original BMW crankcase breather hose is the connecting line that carries crankcase ventilation gases for cylinders 1-4 on the N63 V8 used in the BMW 550i, 650i, 750i, Alpina B7, X5 xDrive50i, and X6. BMW names the part a connecting line and assigns it to cylinders 1 through 4, which puts it on the right cylinder bank. In a positive crankcase ventilation system, a breather hose carries pressurized crankcase air to the air\/oil separator. The separator returns oil vapor to the engine and sends the remaining air to the intake to be burned. The constant mix of heat, pressure, and oil vapor makes this hose a common failure point in the system. The part weighs 103 g and is sold individually.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eBMW put this version into production in May 2012. BMW marks it as exchangeable retrospectively with the earlier part 11-15-7-575-642, so it also replaces that number on cars built before the change. Because the N63 has two cylinder banks, check which bank your hose sits on before you order. This line serves cylinders 1-4 on the right bank only. Plastic connectors on PCV hoses become brittle with heat and oil exposure, and the securing clips can break during removal or during other engine work.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (genuine part)\u003c\/li\u003e\n\u003cli\u003ePart number: 11-15-7-646-086\u003c\/li\u003e\n\u003cli\u003eBMW part name: connecting line, cylinders 1-4\u003c\/li\u003e\n\u003cli\u003ePosition: right cylinder bank, N63 V8\u003c\/li\u003e\n\u003cli\u003eWeight: 103 g (0.2 lb)\u003c\/li\u003e\n\u003cli\u003eProduction start: May 2012\u003c\/li\u003e\n\u003cli\u003eSupersedes 11-15-7-575-642, exchangeable retrospectively\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003cli\u003eWarranty: 24-month parts warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms point to a failed breather hose?\u003c\/strong\u003e\u003cbr\u003eLook for cracks or splits in the hose, broken connectors, and oil residue on the hose or the parts around it.
