Smoke, what smoke? If you want to see smoke, come to my house when I start my vert up...cripes... it reminds me of the old days when they used to fog the neighborhoods for the mosquitos..!! (Granted, I think its an original engine thats never been rebuilt, ...but thats for another year..)

Seriously, I wouldn't worry too much about that. Now...if you start noticing a huge drop in oil when checking the dipstick, then be concerned...
