Blue smoke
Mine does it too, mines not a huge cloud but is noticable. Ive heard its oil that seeps around the pistons into the cylinders and the engine just burns it off. I dont think it hurts anything but burning a smidge of oil.
That's a usuall for an older engine and if u got blow by it probably is jus the rings getting worn out but i wouldn't worry bout it too much cuz once they get warmed up it should be fine
