Black smoke could mean it is running rich, have a scan done, it is probably an engine misfire code and it will tell you which cylinder is misfiring. the last digit is the cylinder, unless it says random missfire, It may be time for a good tune up and don't forget the fuel injection system, Clean out the intake and do an induction cleaning on the injectors.

Aside from making the engine run poorly, what you did should not have damaged anything. In being one tower off, you changed the engine timing. Timing can change the amount of heat in a cylinder.
If there was a problem before you did that, such as a failing head gasket, you may have pushed it into complete failure. What you are seeing may not be oil but condensation in the exhaust mixed with carbon residue from the inside of the pipe.
You didn't mention why you replaced the cap, or, if the engine now has any problems while it's running. if it's missing, first thing I'd do is remove the plugs and see if any have wet or burned on oil residue. If you find that, take a compression test and go from there..

It sounds like it has a bad main bearing, or it is dumping oil in the fuel (bad gaskets) You definitely do not want to run the engine with low oil pressure.
