So im just trying to see if other 2004 bmw 745li's have that, or if it looks like mine, because i would think without that pressure regulating valve, it is unable to regulate ccv pressure in the head on the left(passenger side)?
That's interesting that the passenger side doesn't appear to have the pressure regulating valve... I wonder if this is a new "improved' design?
