[Whizzer]

At 170k miles and with swirl flap linkage falling off decided that it might be sensible to replace the swirl flaps etc..
So far so good injectors 2, 3, and 4, showing signs of moving, 1 and 5 hopefully will also after a soaking with penetrating oil.
Struggling though to move the silver coloured pipe which runs over the camshaft cover as unable to part company with the rubber pipe at the front of the engine. Seems that this is not simply a pipe and rubber hose type connection that can be dismantled?
Can anyone shed any light on where to disconnect this pipe (and move out of the way) so that I can remove the cam shaft cover and intake manifold?

While I have the injectors out - should I be doing anything further to them before refitting?

2009 XC90 D5 185bhp.

Unable to upload a photo but the pipe rises up the front of the engine just to the right of the intake manifold ‘inlet’ over cylinder 4 and 5 diagonally, and down the back of the engine.

Thanks for any assistance.
