Where's the nocking coming from?

White SMOKE, is a lean mixture..... Steam on the other hand would be head gasket IMO, take the spark plug out that isnt firing and see if its wet.

or from cold start engine and put your foot flat on the floor rev it high cut it, check the water bottle for pressure
