Original BMW N74 V12 Cylinder Head Cover Profile Seal, Cylinders 7–12, BMW 760Li and M760i xDrive (2010–2022)

For BMW's N74 V12, this Original BMW profile seal seals the cylinder head cover to the head on the cylinders 7 through 12 bank of the 760Li (2010–2015) and M760i xDrive (2017–2022). A valve cover gasket keeps engine oil and oil vapor inside the head at the joint between the cover and the cylinder head. BMW calls this part a profile seal for the cylinder head cover. It weighs 64 g, is made in Hungary, and is sold as one piece. BMW shows production of the current number starting in December 2015.

Original BMW Parts carry a 24-month parts warranty.

The V12 has two cylinder heads, and BMW assigns this seal to cylinders 7 through 12 only, so check which bank you are servicing before ordering. Part 11-12-8-621-958 replaces 11-12-7-578-669, and BMW rates the change as exchangeable retrospectively, so it fits earlier F02 cars built with the older seal. BMW applies it to the N74 in the F01, F02, and F03 7 Series and to the later N74B and N74L versions in the G12 M760i xDrive.

Installation & Tuning Notes

Excess tightening torque on the cover fasteners can crush the gasket past the point where it seals. Incompatible chemical gasket makers or sealing agents can also react with the gasket and cause it to fail.

Common Questions

What are the signs of a leaking valve cover gasket?
Oil seeping down the cylinder head from the valve cover is the most common sign. Oil that reaches the exhaust manifold can also burn off and leave a noticeable smell while driving.

Does this seal cover both cylinder heads?
No. BMW assigns this seal to the cylinders 7 through 12 bank only.
