- 2009 Audi Q7 3.6L
My Q7 with 3.6L just started smoking and using oil. Replaced valve cover with new PCV valve. Still using oil. Took intake hose off and there was oil in it. Took hose off air box out of PCV but it was not blowing oil. In another forum someone said I could have a cracked head. Could it be something else. Car has 160,000 miles on it.
