oil popping around manifold?

[BOVADDICT]

When I start my car I usually hear a small popping or bubbling noise and it goes away so I think nothign of it. Recently we took my heat shield off and just kinda spaced putting it back on. Today I went to start my car and the hood was up when I realized that there was a decent amount of oil just left of the valve cover on some small cylinder and there was tiny bubbles of oil seeping and making tiny bubbles on my exhaust manifold right by this cylinder and throught the entire gasket. What could this be and how would this affect my car? Would this have anything to do with the popping/studdering when I push boost when I floor it?
