Getting ready to change the plugs on my 06 Expy. Looking at he engine from the front, if you look down on the Front right hand side of the engine just behind the anti lock manifold there is a short line about 1/8 in diameter that seems to go nowhere. Does anyone know where this goes or what it does?
I have included a picture with a blue shop towel behind it so it is visible
.
Is it a 4x4? Looks like the vent line for the 4x4 wheel hubs in the front. It should vent to atmosphere. There should be one on each side, and if you trace them they lead down to the wheel hub.

Thanks, That makes sense. Yes it is a 4X4. BTW, Plug change was a breeze( other than having to remove the Brain) Cracked them, squirted some Berrymans into the well and waited for about an hour.
Did mine last year, didn't break any.. But I only had like 33k miles on it at the time, I just figured it was best to get the original ones out and get the new design in, before they seize up and will break. Put some antiseize on them as well, plus changed all the boots on the coils, cured a misfire I had at the same time
