just from your description it would sound like you have a coolant leak into cylinder #6 with the engine warm. you might want to take out the #6 spark plug and pressure test your cooling system to a pressure slightly higher than the rating on you radiator cap and see if coolant is leaking into the cylinder.

ok, if you have a misfire on #6 and replacing the plug will make it go away (and the plug is wet) it could be a problem with too much fuel flooding the cylinder. If you say it's wet but it's not gas then the next thought would be that it is coolant. Coolant from a cracked head, a damaged head gasket, bad intake something that will go into cylinder #6. At my shop I would get the engine warmed up to your 210 degrees and pull out the #6 plug and pressure test your cooling system. See if coolant fills up in the cylinder. We have a camera that will go down into the cylinder and we would look to see where it might be coming from.

I wish I could be more helpful but you are talking about something inside the motor. Are you loosing coolant? have you had to add coolant to the system?
