I had the same type of leak when I first got my 01 4.4 about a month ago. After about a week it stopped. So not sure what to think. But after cruising the forum a while I came across a link to this YouTube video about changing the VP gasket and in it he shows just where the leak occurs. It's not a step by step DIY but it has some great information on changing the gasket including tip on doing the work without pulling the WP. When I get ready to tackle mine (I need VC gaskets too) I'm going to use his tips for sure. Plus it gives you some encouragement as it doesn't look too difficult.
Good luck and let us know how it turns out.
