So I was driving to college today and everything was fine until I got into the usual traffic, never usually any problems when I get here and as usual, I moved up a few places and continued on. But then as I was sitting there a tonne of white smoke was just pouring out of my exhaust and it just wouldn't stop! Felt so embarrassed cause it was just covering everyone's cars.. I don't know what to do! Scared to drive it any further...
