Hemi Smoking

I finally got my swap done and running, still in tuning stages but its getting better. Im new to the fuel injection world so its definitely a learning experience. I had issues in the beginning with a map sensor that was not wired right so it ran extremely fat, then I got the wires swapped on the map and its running much better. Now I am experiencing oil smoke. I assume some of it is because I dont have a catch can for the pcv yet but my fear is that due to running so rich that I may have washed cylinders out. Is this possible. Background on the motor, it was purchased back in 2005 out of a roll over with 18,000 miles on it and had been sitting in a garage ever since. My other thought is stuck rings, if that is the case can this be remedied or do I need to pull it back apart. I have heard everything from trans fluid to sea foam while running, and water mist to break up solidified deposits. Lots of questions I apologize.
