Original BMW N20 Valve Cover for BMW 2, 3, 4, and 5 Series, X1, X3, X4, X5, and Z4 (2012–2018)

The Original BMW cylinder head cover 11-12-7-588-412 is the valve cover for the N20 engine and closes off the top of the cylinder head on 2012–2018 BMW 228i, 320i, 328i, 428i, 528i, X1, X3, X4, X5 xDrive40e, and Z4 sDrive28i models. A valve cover keeps engine oil inside the head and keeps dirt and debris away from the camshafts and valve gear. On the N20 the cover also houses the PCV valve, which relieves crankcase pressure. That valve is built into this part instead of being mounted separately. It comes as a complete cover with a valve cover gasket set, vacuum pump seal, high-pressure fuel pump seal, damping elements, and mounting bolts.

Original BMW Parts carry a 24-month parts warranty.

The cover itself is normally a lifetime component. The gaskets that seal it to the head are a common replacement item and a common cause of oil leaks or smells, because they harden and crack with age. A new cover is the right repair when the old one is warped, cracked, or damaged in any way. High engine temperatures can warp or crack the cover. A blocked PCV valve can also let crankcase pressure build until it damages the cover, and replacing the cover renews the integrated valve at the same time. BMW's parts data shows this number in production from March 2011. The same cover is used on N20 versions of the F22 2 Series, F30 and F34 3 Series, F32 and F36 4 Series, F10 5 Series, E84 X1, F25 X3, F26 X4, F15 X5, and E89 Z4.

Common Questions

Do I need a new cover, or will a gasket set stop the leak?
If the cover is sound, the gaskets are the usual cause. A warped, cracked, or otherwise damaged cover has to be replaced.

Do I need to buy a PCV valve separately?
No. The PCV valve is part of this cover, so it arrives already in place.

Will this cover fit my X5?
Only the 2016–2018 X5 xDrive40e uses this N20 cover. Other X5 versions are not covered by this part number.
