Just let it idle a while and see if it goes away. Sometimes that happens when you change the oil. It can pool and get sucked in through the PCV system. Try running with the oil cap off and see if smoke comes out of the oil cap. If it does, Thats bad. And check to see if the coolant is getting burned. The smells of car fluids are all very distinct, but they are hard to describe. Do like supran2r said and give it a smell. Antifreeze you cna taste and smell, its sweet and smells like an old gym locker kinda. Power steering or Trans fluid smells kinda like carrot juice/ass. Oil just smells like burning...oil. You should be able to tell. And there is pretty much nothing else that could be burning through the motor.
