X5M catch can continued
Hopefully not too late to revive this thread.
I finally got around to installing the passenger side system and like so many others have seen very little collection. With the system open and engine running I noticed little or no vacuum generated by the port leading to the intake snout. Question that I did not see answered in this thread is why BMW set up the DS so different than the PS? There is significant vacuum/flow on the DS with the dual porting to the intake manifolds and almost zero on the PS. Anyone know why they did this?
