Can't figure out what line coneccts to the open port on the manifold any help would be greatly appreciated

 

Not sure where on your picture this hose place is?

 

Sorry it's hard to see just to the right of that screw there are 2 vent lines and a spot for a third but I have nothing to put on it

 

Nothing. It was without a hose on mine. I don't have any excess hoses and I've taken it off twice. It only has a small hole and I'm not sure it even goes through.

 

Ps. I see you don't have a noise maker, I hope on purpose, if not and if your planning on working on your MINI leave it off. Cap the tube connection or buy or make a delete kit. For me fooling with it is the hardest part of taking the intake manifold off.

 

Thanks for the help, I have the noisemaker just took it off to make it easier to take the picture

 

Highly recommend leaving it off. I fought with it twice. This time I just installed a WMW delete.

 

Same here...if I remember correctly, this is plugged internally within the intake manifold.
