yes if you didn;'t drain the oil after the fuel was filling air box its very well could have also been draining into your oil; and making the oil very diluted and could cause bigger motor issues as fuel; can dry out seals and gaskets and bearings??
SO< did you change oil after the fuel issue was corrected??
if not, I would start with changing the oil., making sure correct amount is in it, as too much oil can cause too much pressure and that can cause blow by which will make your blue ish smoke?
I would also as stated above check your breather line too!
but my guess is you had a over filled motor due to fuel filling into it as well as your air box!
