Maybe clean the engine and see if that helps, or you might have a new oil leak developing. But if its been smelling like that ever since they left the oil cap off, its possible, since the oil fill cap is towards the right rear on the exhaust side, that some oil got trapped in the heat shielding and is soaked and burning off slowly, just a thought.
