Please anyone help me with the question about from where vaccum line comes to oil separator valve on 2002 X5, 3.0 engine.

I am tired with oil separator valve going bad and I am going to try out modification with the placement of oil separtor valve at easy to access location within the engine bay. For this purpose, I am going to break off old pipes going to the separator valve and leave the bad valve in its own position. I am going to run separate flexible hoses from valve cover and intake manifold and run them to the space near headlight on left side as a new location for separtaor valve installation. My problem is I can not see from where the vaccum line comes from to the separator valve. Once, I know from you guys, I can run the vaccum line to the new location and that way at later time it will be easy to change the valve.

So please anyone quickly help me with the information about origin/starting point of vaccum line coming to the separator valve. I sincerely appreciate your help in advance. Thanks

If you are asking about the oil separator vent hoses, this is the diagram. Hose number 2 goes to the Crankcase cover. Hose number 3, goes to the distribution piece. Hose number 4, goes to the oil dip stick. And hose number 7, goes from one side of the distribution piece to the top of hose number 3. There isn't any other vaccum lines coming to the separator valve.

Is it really the valve going bad...?
It freezes up then forces oil out of the weakest point in the engine.
Once it is thawed isnt it back to normal...?
Now you have to find where the oil is forced out of.
Thats where im at. Its happend a second time to me.
My wife was driving it and pulled over after smoke started rolling out of every where. Ofcourse i come to the rescue. check the oil and its fine.
I drive it home with smoke pouring out. I end up going back to work.
At the end of the day I pop the hood look around and see oil on the ground.
I cant find where it is leaking from.
What are the the typical culprits when this happens...?
Ive replaced the valve cover gaskets ccv and pcv...
It looks like now oil is coming from the front of the engine...

No. The valve doesn't freeze itself. The condensate paste, which contains water, freezes. If it freezes in the closed position, then pressure builds up in the crankcase and forces its way out, often through a valve cover gasket.

If the condensate paste is there, it can freeze again.

So I dont think this problem will ever go away unless I move somewhere where it doesnt get below freezing temperature.
I have learned that if you drive gently and try to stay below 2k rpms the car will drive fine.
I drove like this after the most recent time the ccv froze. The x5 ran fine no smoke or anything.
This morning i thouhgt i would test my theory so I bump the gas twice so the rpms would go above 2k quickly... sure enough the x5 began to smoke like crazy!! previous times my wife was driving it so i didnt experience the the problem.

This time I was driving, the car was stallling and there was smoke behind me for a 1/4 mile. Not kidding! I couldnt see the cars behind me.

Im guessing the oil is entering the intake and flooding one or more of the cylinders.

Is this a possibility? Im not familiar with the setup. Just wondering if there is a way for a gasket to blow and allow oil to enter the cylinders....?

I just bought this recently, from a single owner who owned it from brand new with 130k. Its in really nice shape. But i dont think my driving style is a good
fit for the car as i dont do long trips just short ones.

have you guys checked on my threads yet, with plenty of pictures on how to remove the entire intake manifold, rear intake cover, throttle body and replacing all intake gaskets area for the following codes: P0171/P0174/P1158/P1160

Search for intake manifold removal or for these codes above for pictures...

This is a pretty much great diagram vacuum picture showing above, and I hope this should be enough for you my friend who needs it. As you can see, every pieces facing directly to their parts where they connect to. N'less you would like to see certain video specified directly the diagram line you referred to.
