2005 Ford Focus engine

White smoke from the tail pipe is a sure sign of coolant leaking into the cylinders of your engine.

Have you checked your anti-freeze level lately?

Coolant can get into your cylinders from a blown intake gasket, head gasket or both. And you'll soon experience overheating issues as well, if you haven't already.

Because your engine is a four cylinder, it is a lot easier to replace these gaskets. But only for mechanics, not people with no experience. And unfortunately, no mechanic will do this cheaply.
