white smoke

If you live in a winter state that has cold weather, your exhaust will look like white smoke this time of year. The water you see dripping is normal. If you live in a warm climate state, you may have a bad head gasket. You should get your error codes read. Try Autozone. Some auto stores will do it for free. Hopefully your error code will be something simple like a bad O2 sensor. If you bring it to a garage, don't make the huge mistake of offering up any information on any problems. If you say you think the head gasket is bad, they may take advantage and just tell you it's bad. Let them scan the codes and see what they have to say.
