If there is no oil on the plug and the compression is equal to the other cylinders then rings aren't the issue. Coil module being new don't mean coil fire, clean plug don't mean you are getting fuel. If the is fuel and spark then there would be no missfire. Ok so you have a coil pack so I would check plug wire and check injector for that cylinder. First change the wire out with another cylinder of the same length see if the missfire moves to that cylinder. If that is good then ohm the injectore and get back to me with ohms and I will look it up to see if it is in spec.
