Heyo,
I just went through a horrible adventure of buying an '09 3.6, and a week after the purchase, the PCV diaphragm went, meaning lean codes and the Crankcase Breather hole on the valve cover was sucking air like crazy. I took it back to the dealership and they went to replace the valve cover and found valve damage supposedly though I didn't see symptoms. Thankfully, they just refunded us for the vehicle. I am stubborn so I am looking for another of the same vehicle.
TO MY QUESTION THOUGH: Should that crankcase breather hole on the valve cover ever suck air? Or is that always a sign that the PCV diaphragm is bad?
The reason I ask is that every Touareg I have test driven with the 3.6 is sucking air through that hole on the valve cover and I am obviously going to be sensitive to that now. I keep thinking maybe people just don't know that's a sign of a leaking PCV plunger or maybe it's supposed to suck a little? haha.
