Narrative:

I leveled off at approximately 14;000 ft on an IFR flight plan. As soon as I started to make my power adjustments from climb to cruise I had a loud knocking sound followed by an immediate loss of all manifold pressure. I declared an emergency with center and diverted directly to ZZZ. On the descent there was thick smoke in the cockpit and I had to open the windows for ventilation. We landed without incident without power. I am not sure what caused the problem; but think that it might have been a bad valve or cylinder.
