This OEM replacement N55 Valve Cover is the complete valve cover overhaul that includes the gaskets and hardware. Elring has done extensive materials research and testing to offer a new OE-style plastic valve cover that is more resistant to cracks and warping than the original. Fitment for 2011+ E82 135i, F22 M235i, F30 335i, F32 435i, F10 535i, F13 640i, F02 740i, F25 X3, F26 X4, F15 X5, F16 X6 35i models.

If your 2011 or newer N55 "TwinPower" single turbo powered BMW is in need of a new crankcase vent system or valve cover gasket replacement, you should be aware the factory valve cover is a composite / plastic design, unlike the previous engine designs that used an aluminum valve cover. This guarantees that with age, mileage, and thousands of heat cycles, the plastic N55 valve cover will become brittle and frail, and will develop cracks. This is why BMW recommends replacing the entire valve cover assembly with new gaskets and seal rings, rather than just replacing the gasket as you might on earlier BMW engines.

Valve cover and valve cover gasket failure is quite common on these cars. It usually happens right around 100k miles, though its been known to strike earlier. Are you getting a smell of burning oil while driving or while idling at a drive-thru with your windows down? This may be due to your valve cover gasket weeping oil onto your hot exhaust manifold. Not only does this risk running your BMW low on oil, it's also known to start engine fires and safety concerns.

This is an N55 valve cover manufactured by Elring Klinger - an original supplier to BMW for many other engine components. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM-type parts like Elring are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
