I just went out to clear the snow and ice off my car and let it run for a bit. While I was brushing, I noticed a bit more exhaust vapors than normal…not really a big deal to me, as the car usually belches out a lot of vapors when it is cold. I did, however, notice a small column of vapors UNDER the car, from around the area of the catalytic converter (I THINK). Again, not TOO surprising to me, as I know the exhaust is sagging a bit and is in need of repair (just don’t have 1000$ to drop right now on a car that I don’t drive too often). When I crouched down to get a better look a minute later, I noticed that the spot on the exhaust where the column of vapor had been coming from was now leaking water. This is a new one. I figured it was just condensation - hot air meeting very cold air, after all - but wanted to make sure. Is this a sign of dangerous things to come? Could it be possible to have the exhaust welded up as a temporary fix?
