Re: What is part #39-111-709-29 and 39-111-700-24 (archive)

I have no idea what the part numbers are or represent. However, the 750's use two anti-dieseling valves (one for each bank). The valves are attached to the outside of the air filter box.
This could be the "valve" you are listing, not sure.

The "check valves" are more than likely the infamous PCV valve that all the discussion is about. Check Valve is the proper description in MY dealers parts CD.

Thank you very much David.

This is what I thought and needed to hear.

What about the BMW part numbers Morty mentions? Are these the same as check valves? These numbers being:

1ea 11151718642 valve for cyl\7-12 side $30.75
1ea 11151718713 valve for cyl\1-6 side $30.75
2ea 11151715844 gasket (called adaptors) $2.25
2ea 11611708475 gaskets for throttle mtr $2.10
2ea 11151720131 check valve $11.41

Ekkehart mentions in Germany they have mention of a "back pressure stop valves" in their parts catalogue. Are these check valves?

Wonderfully built are they but a bitch to work on or understand (of course I am referring to the 750iL BMW car).
