2002 Mazda 626 smoke coming from the area of the distributor and spark plug wires

There are certainly other possibilities - visual inspection needed.

I already had a valve cover gasket replacement done several months ago and there are no leaks, and no leaks at the spark plug boots. I also had a timing belt replacement done as well. The smoke is coming from the ignition coil area which makes me think that that part is bad. It baffles me because the car doesn't misfire and it runs fine I'm just saying the smoke after driving it for a while. Also, thank you for your response.
