Original BMW Flat Metal Washer for M50, M52, M54, S52, and S54 Valve Covers, BMW 3 Series, 5 Series, X3, X5, Z3, and Z4 (1991–2008)

Original BMW valve cover washer 11-12-7-838-077 is the small flat metal washer used at the valve cover of BMW six-cylinder engines in the 3 Series, 5 Series, X3, X5, Z3, and Z4 from 1991 to 2008. BMW names it simply a washer and gives it a chrome-free CR(VI) finish, which means the surface treatment is made without hexavalent chromium. Each washer weighs 3 g (0.11 oz) and is made in Germany. These washers should be changed when you replace a valve cover gasket. On any valve cover, a washer under the fastener spreads the clamping load and gives the fastener a clean, flat face to seat against.

Original BMW Parts carry a 24-month parts warranty.

BMW has produced this number since January 2007, and it replaces the earlier 11-12-1-714-488. BMW rates the change as exchangeable retrospectively, so the current washer goes onto cars that left the factory with the older number. BMW's parts data puts it on a long run of inline-six engines: the M50 in the E34 and E36, the M52 and M54 through the E36, E46, E39, E53, E83, and Z3, and the S52 and S54 in the M3, Z3 M, and Z4 M models. One part number serves that whole spread of engines.
