AnswerOne potential cause is too much gas. It may be running "rich". Your car may also be burning a little oil.

White smoke is usually water or antifreeze. If you are loosing coolant from the radiator, it's probably a blown head gasket. If not, it is just condensation in the exhaust pipe that is evaporating as the pipes heat up. If the car is running too rich, the unburned gas will cause black smoke and burning oil smoke will be blue.

White smoke is usually an indicator of moisture/water in the system where the "white smoke" is actually steam. There may be heavy condensation or water inside the muffler and the heat of the exhaust is turning it into steam. You can remove the muffler and drain it or you can just let all the moisture/water evaporate eventually.

Can a hole in the muffler cause a car to smoke?

Just having a hole in the muffler won't cause smoke to form. Any smoke coming from an engine is caused by either environment changes (white smoke while engine is warming up), or an engine burning oil (blue smoke). Sometimes even a bad catalytic converter can cause smoke. The hole in the muffler simply gives the smoke a way out. Trying looking for external oil leaks or checking he oil level occasionally to see if it is burning oil. You may see water vapor is there is a hole in the muffler but it wouldn't last long once the muffler warms up and the moisture is burned off. She shouldn't see actual smoke unless there is a problem with the engine.

A sure way to tell is to tell is that the oil will be a milky color and overfull.
