Question Oil Leak Near Valve Cover Gasket

So I am chasing an oil leak in my vehicle. It is coming from pretty high up on the block. My picture was taken underneath the front right of the engine looking up... for some reason this site uploaded the picture upside down...

I originally thought it was the oil pan gasket until I noticed oil residue much higher than the oil pan. Then I thought it was the crankshaft pulley seal until, like I said above, I noticed oil higher than that. I can feel below the back left of the valve cover and pull my hand away with small amounts of oil on my fingers.

The only thing I can think of that would leak up there is the valve cover gasket. I pulled the valve cover off and noticed that oil was getting passed the gasket into the screw post right around where I was getting oil on my hand. If you've ever removed the valve cover, it's right where the engine block isn't perfectly machined flat and the gasket has some RTV sealant to make up for it (I was shocked to see this... they couldn't machine that flat?!)

Correct me if I am wrong, but I noticed that the screw posts into the block that secure the valve cover are drilled completely through the block and have outlet holes in the bottom. I think the oil was making it's way past the gasket and into the screw post... dripping down the left side of the engine block.

Anyone experience this or have any tips? I went ahead and replaced the valve cover gasket and applied new RTV on those two locations. We'll see.
