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
