Underside of intake manifold 3.0L

[CaptainCalf]

Hello all!

I'm new here and have a question

Can anybody direct me to a diagram or pic of the underside of an intake manifold for a 3.0L motor. I have a 05 X3 and just replaced the Oil Separator Valve (OSV) and hoses. While I didn't have to pull the intake manifold there is a vacuum hose underneath it that I pulled off it's nipple/connection and I don't think I got it back correctly as it's a blind connection from up top and now with the new OSV my X3 doesn't smoke anymore but it wont idle either

Thanks,
Rick C.

Actually, I've been looking around and I think the connection that I have wrong is the Idle Control Valve (ICV) hose that runs under the intake. It's impossible to see under there so I think I reinstalled that connection wrong

I have it plugged to the bottom of the intake, but I've read that it may just connect to another hose. Can anybody tell me if that's true?

Also, here's some picks of my blown OSV & drain hose:

Okay, I think I've tracked it down to be the hose off the fuel tank vent valve that should be connected to the throttle body:

Will let you know if that's it!

Okay, I found a pic of the intake under belly and looks like the only way to get the fuel tank breather hose re-attached to the manifold w/o pulling the it off is to remove the lower mounting bracket completely (all 3 bolts)...will let you know if I can pull it off...Wish me luck!

Got it sorted. The FTV fitting was behind and to the right of the OSV, but that didn't turn out to be my problem. The reason my x3 wouldn't idle was due to the ICV not being fully seated...
