Is this a sign of a leaking valve cover gasket? I've changed the oil cap and I still see oil around the neck of the cap and the video shows it going the whole way down so I'd assume its not just coming through the oil cap.. Potentially valve cover gasket? Is there any way to check without removing the cover?
I'm going to guess the seal behind the balancer is buggered and the cam cover gaskets are leaking. Clean the PCV out on the top rear drivers side and see if the cam cover leak continues. There's a "How To" in the "How To" subforum.
