You are probally getting oil in the cylinder from somewhere. Mine I I hope is just the valave seals.

Hows your oil level?Most likley the valve guides in that cylinder.Could it be a stuck injector it being black meaning running really rich.I would check the tune if I were you see were your A/F is at.
