retorque heads to solve issue?

It looks oily, it has that shine. Possibly oil from the china wall seeping and creeping as you drive then when you stop it flows down. The cooling fan and driving kicks dirt and grime on it. The think about china wall leaks is they are not overly prevalent until you drive, they won't leak much if at all until you drive. Speaking of oil leaks, what are you running for a PCV system?

I edited my post to say that the soot actually did have a slight oily feel to it after I wiped it with my finger. My PCV system was a breather on the passenger side, a PCV valve and another breather on the driver side. I just changed the breather on the driver side to an oil cap.
