Exclamation Smoking filter

Today I noticed that my AFE filter has a little smoke coming from it after engine is shut down. It is very little, you have to be standing just right to see it. Is this normal or should I be concered?

Smoking filter

Probably oil vapor from the intake tube.

Smoking filter

I noticed this myself about a week ago on my truck. From what i can tell , it is oil vapor that is left over in the intake tube after the truck gets shut off. The pcv gets pressurized by the air going into the turbo , so when the truck shuts off , their is still going to be a small about of "smoke" left in the tube between the filter and the turbo itself , so it is going to look as the airfilter is smoking............
