Original BMW Crankcase Vent Pipe for Cylinders 5 to 8 BMW 550i, 650i, 750i, Alpina B7, X5, and X6 (2008–2014)

Built for the N63 engine, this Original BMW vent pipe connects the crankcase vent valve to the valve cover for cylinders 5 through 8 on the BMW 550i, 650i, 750i, Alpina B7, X5 xDrive50i, and X6. BMW names it simply a vent pipe and marks it for cylinders 5 to 8, which identifies the bank it serves. The pipe is a light piece at 39 g (1.38 oz), and BMW's parts data shows production beginning in July 2008. It is made in the Czech Republic. With age the pipe can crack, letting oil seep out and allowing unmetered air into the intake.

Original BMW Parts carry a 24-month parts warranty.

A crankcase ventilation system draws blow-by gas out of the engine and routes it back into the intake to be burned, and this pipe is one leg of that path on the N63. BMW marks this pipe for cylinders 5 to 8, so confirm that designation before ordering. BMW applies it across a wide group of N63 cars, including the F07 5 Series Gran Turismo, F10 sedan, F12 and F13 6 Series, F01 and F02 7 Series with their Alpina B7 versions, the E70 Facelift X5, and the E71 and E72 X6. It is a sensible piece to renew alongside a new crankcase vent valve, since both see the same heat and oil vapor.
