Original BMW Valve Cover, Cylinders 5–8, for BMW 5, 6, and 7 Series, M5, M6, X5, and X6 (2012–2016)

BMW's cylinder head cover 11-12-7-636-612 seals the top of the cylinder 5–8 head on the N63N, S63N, and S63R engines in the 2012–2016 550i, 650i, 750i, Alpina B6 and B7, M5, M6, X5, and X6. A valve cover sits over the valves and valvetrain, keeping engine oil inside the head and dirt and debris out. This cover weighs 4.1 kg (9 lb), comes as a single piece, and is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

BMW released 11-12-7-636-612 in July 2012 as the replacement for the earlier cover, 11-12-7-603-653, and rates the change as exchangeable retrospectively. That makes this the correct cover for cars that left the factory with the older number. BMW's parts data assigns it to the N63N in the 550i, 650i, 750i, Alpina B6 and B7, X5 xDrive50i, and X6 xDrive50i, to the S63N in the M5 and M6, and to the S63R in the X5 M and X6 M. One part number covers all three engine variants on this cylinder bank.

Common Questions

Does this cover fit both cylinder heads?
No. It covers cylinders 5 through 8 only, and the cylinder 1–4 head takes a different cover.

What causes a valve cover to leak or crack?
Gaskets harden and crack with age, and high engine temperatures can warp or crack the cover itself. Uneven torque or a poorly placed gasket at installation also causes leaks, and pressure buildup from a blocked PCV valve can damage the cover.
