A question for the car guys (or girls)

Probably water from condensation in the exhaust. I assume this is just when the vehicle's relatively cold, right?

 

Let me google that for you

 

It is the soul of a thousand unborn babies reproaching you for your use of fossil fuels.

Or condensation.

 

In most cases it is water or condensation from built up moisture having hot exhaust travel over.

 

Funny enough, the second link to pop up is this TB thread

 

Haha TB is the second search result.

Yeaaa...its water. Next question, please?

 

I must say, I didn't expect that.

NOBODY EXPECTS THE SOUL OF A THOUSAND UNBORN BABIES!!!!

 

It's amazing how many people use internet to ask question instead of using it to research things!

Google is your friend...

Combustion - Wikipedia, the free encyclopedia

 

I don't think it's water guys. It might be something more sinister....

 

Water vapor is a by product of the combustion. It normally comes out as steam and is invisible, except in weather when you can see it. When you shut the engine off, the steam condenses as it cools, and when you start it up again the water is pushed out by the exhaust. Once the engine gets hot - it becomes invisible steam again. This is the main reason exhaust systems rust out.

 

It's a little-known substance, somewhat hazardous by nature, called Hydrogen Oxide, among others.

 

Not only the presence of it, but short trips never let the exhaust system get hot enough for all of it to evaporate.

 

For short trips it is probably H2O condensate....if it is still apparent on a longer trip and you're using water, you have a bigger problem......headgasket or?

 

TOTALLY IRRELEVENT POST HERE......Mike, wrt your avatar....My son started working on Chameleon yesterday

RELEVENT.....Yup. Water.

Carry on....
