Oil leak(not new), but noticing smoke from hood

Grand Prix GT 2000, ~139K miles.

Hello all. I've had an oil leak for a while (long story short been trying to track down a transmission issue first in order to decide how to proceed. See ......http://www.grandprixforums.net/any-n...tml#post433826 )

On a few hot summer days in the past, I have noticed burnt oil smell and some smoke, but it seems to be a constant thing now for about 2 weeks. When I'm idling at a light, I can see the smoke but it smells more sweet than like burnt oil. My low coolant light does come on but it disappears after I drive for 5 mins. What can I do to determine if the smoke is due to the oil OR if its a problem with a leak from the LIM/UIM(original ones)?

Thanks in advance.
