Original BMW Rear Engine Block Cover for BMW 550i, 650i, 750i, 760Li, M5, M6, X5, and X6 (2008–2019)

Original BMW rear engine block cover 11-14-2-446-298 seals the back of the engine block on the BMW 550i, 650i, 750i, 760Li, M5, M6, X5 xDrive50i, X6, and Alpina B6 and B7 from the 2008–2019 model years. The cover sits on the rear of the engine, hidden behind the transmission, and it is a common leak point on these cars. Over time the cover will eventually start to leak. Because it lives in such an awkward spot, getting the right part the first time matters.

Original BMW Parts carry a 24-month parts warranty.

This cover uses a billet aluminum housing with an integrated Viton seal. It also adds sealed surfaces that encapsulate the leaking engine oil galley plug. It is the rear block cover, and it is sold individually as a single cover.
