My 2005 3.5 with 214,000 miles is smoking from under the hood when I drive it. I checked the coolant levels and oil etc. - topped all off and the oil was not milky. I get a strong exhaust smell in the cab while driving some of the time. What’s going on here?

Probably something like your valve cover is leaking oil, which drips onto the exhaust pipe and causes the smoke when it's hot. Typically a mechanic would shampoo the engine (to clean off years of gunk) and ask you to come back in a couple of days to see if they can determine the source of the leak.

Could be the flexpipe as well.
Is it a little louder than normal?
If not then I agree on a oil leak. Will run down to the edge and drip onto the manifold causing it to smoke, and could technically be a fire hazard
