7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Valve cover gasket replacement - runs rough @ cold start

So using the excellent resources on this forum I am midway through replacing my cvs gaskets.
Also rough idle after cold starts. Code is for secondary air system. Decided to clean valves and passages while they were somewhat accessible. Found hard plastic sec air pipe under intake manifold broken off at connector. Click image for larger version

Hopefully this will help some others who have posted with similar problems.
Also found this vinyl cap in the center connection of the crv header. Does not look like it belongs. Has anyone else seen this?
It looks like the free samples that caplug sends out to mfg eng.
Any help is much appreciated.
Btw. All the rubber gaskets were hard as rock.
