Any oil will smell, far from odorless. Coolant also has a distinctive smell, can't miss it. Steam will dissipate, smoke will not--check in a closed place.
Yes, there are coolant hoses that run to the heater behind the engine and, of course to the radiator. The coolant is pressurized so it can continue to leak for some time after the engine is turned off.
Not seeing anything on the ground or on the bottom of the X?

i've been reading all morning on here, seem like most of the 8cylin smoke is coming from exhaust. Mine is only the engine. it kind of burns like oil. on after about a 20miles drive and park, i can smell sort of burnt plastic in the engine.
even after the engine is off, it will continue to have smoke and it slowly slowly fades away.On the driveway, there are drops of oil seems to be directly under the engine block and only the drop of coolant is directly under the exp tank. I've had the oil leak for quite some time now. would it matter that it due to me driving to work is less than 20miles and would it accumulate sludge of somesort in the oil?

I would suggest doing a pressure test on the cooling system. You can get a tester on loan from places like Autozone or O'Rielly's. Test it at no more than about 15 psi. You just want to see if there are any leaks in the system.

thanks aquila, i ran a pressure test few weeks ago, seems only area that had coolant leak was the water cooling connector (T-shape connector under the expansion tank) i was looking for other signs of coolant leak, but couldn't find anywhere else.
thanks again guys. would this be due to i topped off M1 5w-30 the other day? It does feel like it's consuming more oil than usual. Should i do an oil change and use the high mileage?
i appreciate all the tips, i can definitely check when i get home tonight if there's a specific area you guys recommend to look at.
