Original BMW Valve Cover Bolt with Seal M6 x 42.5 mm for 3 Series, 5 Series, 7 Series, X5, Z3, and Z8 (1991–2008)

This Original BMW collar screw, part number 11-12-7-568-809, is the M6 x 42.5 mm valve cover bolt with seal that clamps the cylinder head cover down on four-cylinder, V8, and V12 BMW engines from 1991 to 2008. The collar under the bolt head spreads clamping force across the cover, and the seal keeps oil from weeping out around the bolt hole. Each bolt weighs 22 grams, is made in Germany, and has been produced in its current form since December 2006. The bolt is M6 x 42.5 mm.

Original BMW Parts carry a 24-month parts warranty.

One bolt number spans a wide spread of engines. BMW applies it to the M42, M43, and M44 four-cylinders in the E30 and E36 318i, 318is, and 318ti and in the Z3 1.8 and 1.9. It also serves the M62 V8 in the E39 540i, the E38 740i and 740iL, the E53 X5 4.4i and 4.6is, and the E52 Alpina V8 roadster, plus the N73 V12 in the E65 760i and E66 760Li. That breadth means a single part covers four-cylinder, eight-cylinder, and twelve-cylinder valve covers.

Common Questions

Does the bolt come with its seal?
Yes. It is supplied as a valve cover bolt with seal, 6 x 42.5 mm.

Will it replace 11-12-1-721-877?
Yes. BMW superseded that number with 11-12-7-568-809 and marks the change as exchangeable retrospectively, so the new bolt also fits engines built with the old one.
