I just placed an oil catch can in line with my PCV valve, and i realized that my PCV valve, oil dip stick and valve cover vent all blow white smoke when the motor is running... furthermore, after putting 30 miles or so on the car, i pulled the catch can, and found a white, frothy substance around the inside of the nipple of the catch can, and it also turned the oil inside the catch can a coffee color.... what is this white smoke + substance.... is it gasoline??? help please!
