Hi all,
I was checking my oil and noticed that the hose that feeds into the airbox had popped off. The small hose that runs out the right side of the airbox. Can anyone tell me what that's for? Should I be concerned?
Thank you.

I think there is a small misconception on your part as to what the PCV system is or does. It vents blow-by gasses off and as long as the PCV is working the system is always at a positive pressure and does not suck into the valve cover. But the issue is there will be some air sucked into the intake air tube that is not filtered directly into the intake manifold. Though this is a small amount of dirt and changing the oil would be a good idea but it would not be an immediate concern for me.
