So for a few months now, I stupidly have been driving my car while there was a strong smell of gas fumes coming through the air vents when I would use the ac or heat. I wrote this off and only recently decided I should get it fixed as it might be an exhaust issue. Could I have been inhaling carbon monoxide due to a faulty exhaust system leaking it into the car while driving? Even if I had no symptoms (no dizziness, nausea, headaches) could I still have been exposed to small amounts that would have accumulatively affected my health in any way? I read that small exposure over an extended period could affect heart, lungs and brain.
Hello~I would ask your doctor, I would think it would depend on how long you were exposed each time, if it were long periods, then possibly it could have done some damage, but if they were short intervals, then probably nothing to worry about.
