Help me identify "This Hose"

[DanDDan]

I need to ask a novice question. Please help me identify the hose marked "This Hose" in the attached image. It runs from the Oil Filler pipe to to a location in the inlet air housing, downstream of the air filter. What is its purpose?

Thanks,

It's a part of the PCV system. Are you wanting to remove it?

No, when I had my oil changed last, I also had the serpentine belt replaced along with the air filter. My mechanic failed to plug this hose back when reassembling the air intake system. I plugged it into the only place it seem like it would go on the intake housing and that made me curious as to the purpose of the hose. If it's part of the PCV system, then I would like to know where the PCV valve is located?

PCV is located on the rearmost end of the drivers' side valve cover
