Original BMW V12 Engine Block Cap with Seal for BMW 760i, 760Li, and M760i xDrive (2003–2022)

The Original BMW cap with seal, part number 11-14-7-506-384, closes off the water distribution pipe at the top of the engine block on the V12 BMW 760i, 760Li, and M760i xDrive. BMW calls it a cap with seal. The seal comes on the part, so the cap arrives ready to install. It mounts on the top section of the block, where the distribution pipe carries coolant through the engine. BMW started production of this number in January 2003 and has kept it in service through every V12 7 Series since then. It is made in the Netherlands and sold individually.

Original BMW Parts carry a 24-month parts warranty.

A cap of this type holds coolant pressure at an opening in the block, and its seal is what keeps that joint dry. One part number covers two V12 engine families. It fits the N73 in the E65, E66, and E67 7 Series and the N74 in the F01, F02, and F03, including facelift cars. The G12 M760i xDrive also uses it with both its N74B and N74L engine versions, so V12 owners from either generation order the same cap.
