Just got home and can see your pics now Danish - couldnt see them from work.
On your plastic pipe from IC to IM, whats the hose you've got on the port you'd put the DV on? Its got a metal cap to it.
I've been basing this on the K04 with part numbers image thats floating around and cant see that pipe on that one.
I assumed its just the short slightly kinked pipe on that image that goes on this port up to the DV bits
Note to self - must sort out ETKA!
