Is Water In Exhaust Bad?

It all depends. The presence of water in your exhaust is not hazardous, and in fact, it is commonly referred to as “normal.” Water vapor is the sole component of combustion gasses. Because it condenses in a chilly exhaust system or an outstanding exhaust system, it will drip from the tailpipe. You will not observe any liquid dripping from the exhaust if the system is fully warmed up. A healthy engine will have water droplets dripping from its exhaust, and this is a good indicator. In other words, the air or the air-fuel mixture is completely combusted during the combustion stroke. The presence of black smoke after burning indicates that the charge contains an excessive amount of fuel. Carbon monoxide and nitrides would not be released.

When you see a puff of white smoke rising from your stove, you can be sure that some of the fuel hasn’t completely burned. Your car’s efficiency will suffer as a result, and its performance will suffer as well. Added to that, there will be toxins. In other words, a healthy engine produces clean smoke including water droplets.
