Part number for clip on the bottom of the valve cover?

[blakteky]

Does anyone know the part number for the clip on the underside of the n55 valve cover? It's slightly to the intake side, in the middle. It seem to be pcv related. It has two ears and a plastic square that seems to move up and down to block air flow with vacuum or pressure. One of the ears snapped off mine and this clip was laying in the bottom of the valve train.

I've looked for diagrams or part numbers for a couple hours now. But the best option I have to buy a used valve cover for this little part.
