Pulled the intake to do the valves and it's been a few weeks since I initially took it down. Now that it's going back together, I have this port but I can't find an extra hose for the life of me.

I checked out a couple write ups for removing the manifold and it wasn't mentioned in them or the Bentley manual, so I'm hoping I'm not losing my mind.


It the rear most port, just above the PCV hose fitting.

 

on my n18 the same port is there on the intake but it isnt drilled out

 

I did try sticking a screwdriver in and it stopped, but then I looked at it (using a mirror, so it wasn't a good look) and I couldn't tell if it had a smaller hole or not.

Maybe I'll try a piece of mechanics wire.
