Can someone please identify this part for me.

Thanks for your time. I put my transmission back in a couple nights ago. I don't think there is anything that goes on the inside of the bellhousing(clutch side). It's gotta be a vent to something. I'm gonna check my headlights tonight. I have both of them removed. Maybe there is a vent tube on them. It has dust on the inside of it so it's not an internal part.

Thanks for checking later.
