Hi Antbann, I'm not being awkward here,
, but I'm having a little
trouble understanding where you mean.
First off, there are no vents here and everything should be connected.
Secondly, I doubt very much that you removed your inlet manifold, and
you mean that you removed the big black plastic trunking that connects
from your big black air filter box at the front of the engine to the top
of the throttle body to give you access to your IACV.
Please correct me if I'm wrong.
When you say:
i saw a black pipe come up from below the engine at the back,Do you mean you saw a hose, the same size as the one from your Cam Cover,
coming back up between the Throttle Body and the engine, and that the black hose
from your Cam Cover is also in the same area but not connected to anything?
If you follow the hose down that is marked with the red arrow in this picture,
where does it go to?
Is it connected to anything at the other end?
Is it in this area that you seem to have a second black hose that is not connected?
Is it the same hose, but has been cut in half?
