I'm getting oil leaking down to my catalytic converter. When it's hot, it'll start to burn off and smoke right under the car. Smells like oil.

When I open the hood, there isn't any oil being burnt off that I could see. Near the back I could see some fresh oil though, around the passenger side top left of engine, valve cover gasket.

Are there common areas that would leak oil? Hoses etc. I'm thinking it's leaking near the back.
