WTB: Retarding valve p/n 11631711519

[Vman]

I'm looking for a retarding valve (part 11631711519) that goes on the vacuum line to the Thermovalve / purge valve. If anyone has one, please DM me. Thanks! Looks like this: https://www.turnermotorsport.com/p-3689 ... zEPf6M4nHw

It's just a 8mm vacuum check valve. Any auto parts store should have it, or 100s of places online.
I don't think its a critical component, I'm not running one on my car, bet others aren't also.

FYI My 1993 Volvo 245 runs with the exact same plastic B&W valve coming out from the plenum since new. So I’d do what kojo suggests, try to get it from any auto store (maybe will not be available under any BMW reference part number) but most likely you can find it. Let us know when you do.
