H3 Positive crankcase vent tube.

Is there supposed to be a tube there? Can someone send me a picture if there is and where it goes? Here's what I have on it.

I think mine has that same plug without the hose clamp.

I think that would be used for a (vacuum) power brake booster (on Colorado/ Canyon) which our trucks don't have.

Mine's plugged the same way, but with a factory spring clamp instead of a pipe clamp like yours.

My 08 has just the plug.
