Water leaking from exhaust

Isnt it like taking a piece of metal, letting it sit and cool then warming it up with a lighter? You will see some slight moisture. Now think of that on a greater scale.

This thread is just funny. Fuel tanks at gas stations also collect water condensation that gets pumped into your tank. Your gas tank in your car collects condensation, your intake collects condensation, etc. Either way there is water that runs threw your motor.
 
But if you look at the the ops topic it built up under his car!

"If we look into the chemical make-up of gasoline we will notice that it is made of Carbon, Hydrogen and then requires oxygen to combust. After the reaction, the by products are Carbon Dioxide and water. After we balance the equation it will look something like this:
2 C8H18 + 25 O2 to 16 CO2 + 18 H2O. You will notice that the byproduct contains water. This is part of the reason it contains water. Most of this is vaporized because of the intense heat created during combustion. Depending on the type of exhaust system the car has, the vapor may or may not condense on the inside of the exhaust pipes. This would lead to the appearance that it is dripping water. Also water can be either in the gas tank of the car or in the gas you purchase. The water is NOT part of the gas, but is separated and just ends up in your tank. Your fuel pump will pump the water into your motor and it will be vaporized and then be expelled out your exhaust system. Depending on if you have large or trace amounts of water it could effect how your vehicle operates."

Water is a byproduct regardless of whether is condenses or not.

Thanks. All of that is correct, but is totally irrelevant to the original poster's question. He asked if the water coming out of the exhaust pipe is condensation. The answer is Yes. The source of the water is irrelevant -- it may be a byproduct of combustion, or a product of the catalytic reactions in the catalytic converters, or it may just be in the gasoline.

You're confusing chemical changes with physical changes. The combustion processes and catalytic processes are chemical changes where water is produced chemically as a byproduct. Physical changes are when solid water (ice) melts to a liquid, or when liquid water is boiled to make a vapor (gas). Think back to your 3rd grade chemistry class.

The original poster did not ask where the water came from. He simply wanted to know if the water was condensation. And it is, based on a physical change of water vapor to liquid water. In other words, the condensation results from a physical change of the water vapor that is made by combustion and catalytic processes (and which remains gaseous when the engine and exhaust system is HOT) to back to liquid water when it cools (like when the exhaust pipes are cool). When the exhaust system gets hot, there is enough heat to prevent the water from cooling into a liquid state and the condensation goes away. Again, the source of the water is irrelevant. Water is water, regardless of whether it is a gas, liquid, or solid.
 
It appears to me he claims it is underneath his exhaust in the first post. Who says its not the ground thats producing condensation as the area ( car ) above is warming it up? I have noticed plenty of times a damp spot under he car after pulling away when I let it warm up in times when it was colder at night

ToddG is 100% correct either way around the OP.
 
I wondered what that hole was for but you cant deny the fact that you never pulled away and noticed a bit of moisture on the ground after letting the car warm up depending on the weather situation. I noticed stuff like that with different cars.

I still do agree with ToddG but my point is just towards the Original post.
 
Guess I will clarify my post a little bit...

After running it for about 10 minutes, I shut off the car and noticed water dripping rapidly from the tip of the exhaust and also at the small hole mentioned above. I noticed this last winter when I purchased the car.

I will have to take a pic next weekend to show what I am talking about - it seems to be an excessive amount of water coming out.

My 02 Taurus does not do this and my 00 V8 LS has a code continually coming up (exhaust leak) - just curious if anyone else has water coming out during the winter time.

FYI - car sits during the winter time and I do not see this water during the summer
 
To answer you question, I drive mine thru the winter and no I have not noticed any type of "liquid" coming from the exhaust. But I have seen a mysterious liquid coming from other cars exhaust when they hit the gas taking off from a red light.
