Original BMW Engine Valley Cover Cap with Seal for BMW 5, 6, 7 Series, Alpina B7, and X5 V8 (2002–2010)

The Original BMW cap with seal is the engine valley cover that sits under the intake manifold, between the cylinder heads, on the N62 and N62N V8 engines in the 545i, 550i, 645Ci, 650i, 745i, 745Li, 750i, 750Li, Alpina B7, and V8 X5 (2002–2010). The seal is part of the cap and is not sold on its own, so you replace the cover and its gasket as one piece. The part weighs 1.1 kg (2.3 lb), and BMW shows production of this number starting in July 2001. A coolant leak around the intake area is the sign that this cover needs replacing. It is made in the Netherlands.

Original BMW Parts carry a 24-month parts warranty.

On a V engine, the valley is the open space between the two cylinder banks, and a cover closes that space off under the intake. BMW uses this one number on both the earlier N62 and the later N62N engines, so pre-facelift and facelift cars take the same cap. The cap is tied to the coolant plumbing in the valley. Whenever the cooling pipe under the intake manifold has to be replaced, this valley cover is required as well, so order the two parts together for that job.

Common Questions

Can I buy the valley cover gasket by itself?
No. The gasket is part of the cap, and BMW does not sell it separately, so the complete cover is the replacement.

Do I need this cap when replacing the valley cooling pipe?
Yes. The valley cover is required whenever the cooling pipe under the intake manifold is replaced.

Does one cap cover both N62 and N62N cars?
Yes. BMW uses this same number on both versions of the V8 across the 5, 6, and 7 Series and the X5.
