Default 2008 Mazda CX-9 Grand Touring, Code P0301. Cylinder 1 smoke

I had all spark plugs, all ignition coils, air intake manifold gaskets and valve cover gaskets changed. The misfire in cylinder 1 has stopped. The mechanic noticed oil on the old ignition coil and said it should burn off after he changed everything. It was changed on Friday. I drove over 250 miles. Last day driving was Sunday and the cylinder is still smoking. I wonder if it's something else wrong or should I wait longer for it to burn off. Also, yesterday my A.C. has started to turn on automatically for 30 secs when I shut off my vehicle. My car has over 230,000 miles.

AC issues is a faulty relay, I think there's 2 separate relays.
Smoke may be a leaking rocker cover gasket.

Thank you for your response. The smell has died down some today. I definitely need to check out the A.C. It blows strong but doesn't get cold or hot when I change the degrees.
