Help whats wrong!!

I decided to do an oil change in my 83 200x today and did it like I always have. I started it up and everything was normal. It was warming up when I turned around and looked into a wall of blue smoke. I revved it up a bit but nothing changed. I turned it off. I took out the spark plug and smoke came out the hole. I put the plug back in started it up and eventually it quit. This never happened before. Does anyone know what happened? Thanks

Also, what kind of damage might I have?

could it be that the gap in each ring linded up to let oil pass through the gaps and be burned. does it still smoke.

Yah I used the same oil Quaker State 10w-30. It stopped smoking and it appears to be back to normal. I just hope there is no damage to the top end. The spark plug gets carboned up quickly. and there is oil around the plug.
