fresh oil from ccv???

[ns954]

Hello all.After a recent oil change,i noticed fresh "clean" oil had coated my lower ccv hose.More oil than i am used to seeing.My driveway has more spots as well.The actual blow by vapor coming from the tube is the same,but this fresh oil concerns me.I did slightly,very slightly, overfill it with oil.Now,after 150 miles,the oil level is at the very top of the mark.So,i cleaned the tube,and drove it approx 36 miles.There is still fresh oil on the tube.(elbow connection).No abnormal smoke,noises,fuel comsuption,power issues,etc.Could this be an early warning sign.Or would a very slight overfill cause this.It's never happened in the past.Thanks everyone.
