Hi all

so i went to see the car and there was little white smoke and blow by coming out of the engine (dip stick) and I asked around some said it was normal because of the turbo

so I need your help guys, if someone can send me a video or post a video of a normal engine with a perfect condition so I can used it for as a reference , the sound and if you pull the dipstick how much air and smoke comes out

I have asked like 7 people , they all said something different

any help will be highly appreciated
