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.
The vacuum hose at #6 is ONLY used on the older I6 E39 models, (ex. 528i's).
Save your money and just get the Cold Weather CCV version as a kit, and buy the (2) additional hoses needed.
You should also buy the New Oil dipstick tube as well...
Link to different parts...
Link to my thread:
Link to Cold Weather CCV kit at E-BMW-Parts.com (BMW Dealer in Peabody, Mass. - best price I have found for the kit):
Another great place to purchase parts (another BMW dealer, but in Ohio):

You can see now that the "kit" is made up of numbers 1,2 and 3.
To complete the "kit" to include all insulated hoses you would need:
• 11 61 7 532 629
Vent hose (insulated)
• 11 61 7 504 536
Return Pipe (insulated)
which are numbers 4 and 7 in the diagram I posted above.
If memory serves me correctly you do not need part 6 on a 5 series.
That does not apply to the e39 and there is no place to plug it into the CCV.
