It depends how much water was put into your tank and if it has ran through your auto. Usually if a car has been left to sit for a period of time condensation will build in the gas tank which will cause white smoke to come from the exhaust. If water was put into the gas tank it is best to drain the tank and adding new fuel with a quart of fuel drier. The car will most likely not run if the water to gas ratio is high but as far as permanent damage goes it is not likely. Water would have to sit for a long period of time to corrode and make a hole in your tank which will cause the gas tank to have a leak. In some cases your car might have a misfire if water is in the fuel lines. The best thing to do is to go to your local honest mechanic and have him run a diagnosis.
