i dont know what you mean exactly, but if you mean that the exhaust has changed to a steam you most likely have a head or a head gasket problem.
Most gasolines have a high water content,When they are burned in the engine the water turns to steam and goes out the exhaust.As the exhaust system cools off, the steam condenses and water can run out of the tailpipe
Boil it
That is called condensation. When you start the engine the exhaust system/pipes are cold. When the heat from the engine exhaust passes through the exhaust it makes it sweat. That is normal.
You need a new Head Gasket.
The sun causes dehydration by evaporating moisture from the skin, which can lead to a decrease in the body's water content. This decrease in water content can trigger a compensatory mechanism in the body that causes an increase in water retention, leading to swelling.
Your in a high condensation area and it has collected in your exhaust system and causes old mufflers and exhaust system to rust.
creates landscape features such as valleys, and plains reduces the height of mountains over times starts the creation of sedimentary rock such as sand stone, causes land slips, changes the clarity and nutrient content of water, creates soil, changes nutrient content of soil. the list goes on...
Contrails are long, artificial clouds that are man-made, sometimes trailing an aircraft. They are made most commonly by the water vapor in the exhaust of the engines of aircrafts. However, they can also be made from changes in the air pressure.
different climate changes in the water
Evaporation causes water to become a vapour.
Water vapour due to condensation in the exhaust pipe.
AnswerCondensation. The hot exhaust system is prone to do this, sometimes mufflers have a small hole in them to act as a drain. Don't worry about it.
