retorque heads to solve issue?

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.

Good, having the breather and PCV on the same side rendered it useless.

On the potential leak issue, I would get that area squeeky clean, go for a drive around he block and stop and take a paper towel and blot along from the header side to the intake and see where its coming from.
