Original BMW Valve Cover (Cylinders 1–4) for BMW 550i, 650i, 750i, Alpina B6/B7, X5, and X6 (2013–2016)

Covering cylinders 1–4 of the N63N V8, Original BMW cylinder head cover 11-12-7-636-759 seals the top of that bank's valve train on 2013–2016 BMW 550i, 650i, and 750i models, the Alpina B6 and B7, and the X5 and X6 xDrive50i. A valve cover sits on the cylinder head over the valves and valvetrain, keeping engine oil in and dirt and debris out. On a V8, each cylinder bank has its own cover. BMW marks this one ZYL. 1-4, its shorthand for cylinders 1 through 4. The cover weighs 4.2 kg (9.3 lb), is made in Germany, and sits at position 1 on BMW's valve cover diagram.

Original BMW Parts carry a 24-month parts warranty.

BMW began producing this cover in July 2012 for the N63N engine. BMW's records show it across the facelifted 5 Series and 7 Series, the 5 Series GT, the F06, F12, and F13 6 Series, the F15 X5, and the F16 X6. On several xDrive models, BMW shows the N63N in both 4.0 and 4.4 variants, and this cover is fitted to each. The part is bank-specific. If you plan to replace both covers, the cylinder 5–8 side takes its own cover, so check which bank is leaking or damaged before you order.

Common Questions

Does this cover fit both sides of the engine?
No. It covers cylinders 1–4 only, and the other bank takes its own cover.

What damages a valve cover?
High engine temperatures can warp or crack plastic or metal covers. Pressure built up in the crankcase from a blocked PCV valve can also damage the cover.

Why does my engine leak or smell of oil around the valve cover?
Valve cover gaskets harden and crack with age, which causes oil leaks or smells coming from the engine.

PMB carries this cover for N63N owners tracking down oil leaks on the cylinder 1–4 side.
