2013 Tiguan. I removed my skid plate to change my oil yesterday and saw this gunk running down the pan. It was mostly dried so I couldn't really tell what it was, and it was brittle so i could break little chunks off. I'm no mechanic at all so I have no clue what is happening. From the pics in this link http://imgur.com/gallery/gp0BGvL can anyone tell me what this might be? Thanks.
I was wondering what the oil cap had to do with it by the looks of it. If it is the pcv valve, can it cause permanent damage? I'll check this out immediately but I'm curious... always trying to learn more

What specifically am I looking for if I remove oil cap? I have not tested the pcv functionality. Over the past 4 or 5 months I have had to top off the coolant 3 times, although I haven't seen or smelled any signs of a leak until this oil change.
Ok. No build up of anything under the cap. Looks perfect. Just read that a failing pcv can cause a whistle. I've been hearing a whistle when accelerating over 30 miles per hour. At first I thought it was a distant siren but realized it was the car. It dies down and stops when I stop accelerating. I'll check the pcv valve tomorrow morning when I can see what I'm doing.
A malfunctioning PCV valve can cause oil blowing out of the seals. Over-pressureizing the crankcase.
In the old days, they use to just vent the crankcase to the atmosphere which was a major cause of smog. That was the first thing they fixed when they started doing pollution controls.
