PCV hose with check valve has oil on it

So I got the message as a few suggested that although my VC gasket may need to be replaced, it probably won't cure my idle issue and that I probably have a vac leak somewhere else still.
One other possible clue is that the vac hose that goes from the PCV nipple to the intake manifold always has a light misting of oil covering the hose.
No other hoses in the engine bay have this type of "wet" look to them. I've cleaned up the hose many times and it always returns. The hose itself is new as well as the check valve and the crankcase vent nipple w bushing is secure and not leaking. The oil film only appears on the hose itself, as if the oil is seeping through the hose somehow. I don't have an insulator around it like most I've seen... Not sure if that actually has any major effect?
I have also replaced the big PCV hose that has the coolant line in it with a good used one because the other one was dry and split. I had the batt D/C at this time.
