Leaking oil...

So I was installing my WAI today, and while removing the tube from the top of the valve cover I noticed it's been leaking oil a bit. I'm not really even sure what these tubes are for but one would imagine there shouldn't be oil in them. How bad of a problem is this?

Lol it's one of the Positive Crankcase Ventilation (PCV) hoses. Oil vapors and oil at times make it through, travel to the intake and are burned off in the engine.

It's fine/normal.

I just replaced the hoses on mine. The rubber breaks down over time and has to be replaced.
