245 DL dead in a giant puff of white smoke on the Houston Beltway! 200 1986

It's hard to make a serious cloud of white smoke (steam, yes, but not smoke).

Blue to blue/white smoke is oil. Broken piston or cracked cylinder wall are the most likely culprits. That, however, would not cause much gasoline odor, nor would gasoline drip out of the exhaust pipe.

Black smoke is partially-burned fuel. Major fuel injector failure could cause a black cloud and lots of gas smell.

A white cloud probably water vapor, but could be gasoline vapor or brake fluid burning. I would be impressed if you could put enough fuel through a broken injector to cause a big cloud of gasoline vapor. I have seen a vacuum assist fill up with brake fluid and fail, creating a smoke cloud that would make the Blue Angles blush every time the brake is applied.

1) Check coolant level - did you loose some?
2) Check brake fluid level - same question
3) Remove fuel injectors. If you were spraying enough fuel to make a cloud, the problem should be visible.
