Over-filled engine oil
 

I over-filled my engine oil yesterday and noticed blue/grey smoke coming from the exhaust. I realized what I had done and drained/replaced my oil today however there is still grey smoke coming from the exhaust.

Did I permanently damage my engine? I believe its just burning off the excess oil but a second opinion would be great. Any idea on how long this might take?

Yes, I realize I'm an idiot for over-filling it.
