if it smokes on start up its most likely valve seals or valve guides

and the smoke in my sig looks more bluish, therefore its oil and not just carbon or anything else

so its either what I said or Pdubinator, but like he stated its more if its doing it all the time


do a compression test, and a leak down. that will be able to differentiate much better than our guesses online, and what color the smoke might look ya know what i mean
