I drive my car pretty hard and I am wondering if anyone thinks that this is a gasket replacement time? I have white smoke out of the tailpipes but then again I do have cold mornings and afternoons. Anyways this car has pretty humid air coming out of the tailpipes and I have checked the coolant level and it doesn't seem to be draining out. Could it be a small leak? I checked the sparkplugs and it doesn't seem to be having any water pour out of any of the cylinders. Does it necessarily have to pour out water? would small leaks make the car spill out water?.
