It makes me feel good when, after all this work by everyone, a question is answered here, in the forum, well before someone even thinks to ask it.

Happened just now, for example, for this vacuum port:

I have 2 issues for the forum - one a question and the other a comment/suggestion.

The new oil separator(OS) has a small port that was unplugged upon receiving it. Official BMW records say that port is "required" for my model year car. My old OS is not have it so I am thinking just plug it up. What should I do and if needed where does it bloody connect to?

In order to connect the breather hose (valve cover to OS) I used a heat gun to soften the OS side due to it being very stiff. I actually broke the first OS trying to connect this one. (urrrrgggg!) Sometimes these aftermarket kits require a little finagling right?

Responses appreciated. Here is what I am talking about.
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
