Hmmm. Keep up posted.... but listen. I was outside after reading and seeing the pic of your oil leak earlier today. At the corner inward fence post, image an "L" shape, i hang a bug light occasionally. Well, i hose clamped a piece of round stock i bent to pertrude up and outward, with a hook shape to hang the buglight, from the fence post. Long story short. The round stock is starting to rust after a few years. But the rust mark running down from the fencepost, appears to ride the hoseclamp then comes out partially around it and looks like it is actually leaking rust from a different area on the hoseclamp. I suspect there is a very minuet vavle cover leak from gasket then trickling around the exhaust manifold, which is super hot on a longer ride, thinning the two or three drops looking like river running down da block. As previously mentioned. Look at the valve cover gasket.
On a side note. You would make James Bond look bad, if there was enough oil in the exhaust passage to leak out of the manifold to trickle down the block, to create an external leak. Clouds would block the road behind you.
