You could well have leaky valve cover gaskets allowing oil to run down on to the exhaust. If you clean the area between the exhaust manifold and the head, you should be able to see if it's leaking.

The smoke out of the exhaust is most likely worn valve seals and/or guides which is probably not what you wanted to hear.
