looks like it is coming out of that bolt for some reason. can you crank it up and let it run and look for the leak?
or better yet, go buy the dye and black light. if you weren't so far away i would do it for you. i have everything here. but poor the dye in the crankcase and drive it for a little bit. then put on the glasses and shine the light and you will be able to see where it is coming from.
I thought that bolt too, but couldn't figure out why the manifold bolt would leak oil. Can you get that dye stuff at a regular auto parts store? I tried looking while running, but all I saw was the smoke.
