Also, check and see if the gaskets around the WP & T-stat are still OK.
Also, once the car is up to operating temp, I would pull over and pop the hood. If you have a friend, I would ask him to rev the engine as well while you check under the hood. That might show the leak.
Another culprit that will make a car smoke is a failed CCV, which in your case might be coincidental, but making you chase a different demon.
