RE: Water/Vapor from Tail Pipe
One of the combustion by-products of an internal combustion engine is water. This by-product when combined with humidity, (and not combinedwith humidityalso)and a cool exhaust system will produce water out of the exhaust pipes.
The condensation is elevated by the cold winter temperatures, and long exhaust pipes...
As long as the water does not contain antifreeze, you have no wories...

The hot water vapors condense on the cooler exhaust pipe. Once the pipes heat up the water wont condense back & remain in gas/vapor form.

My turn to say the same thing with a few different words.
This water is in vapor form when it exits the cylinder but condenses into water in the cold exhaust. That's why water pours from a cold engine's exhaust pipes.
Once the exhaust system warms up the water combines with the other byproducts and remains in vapor form until it exits the exhaust.

Water is NOT a by product of internal combustion. Hydrogen, yes. The water is already in the air before combustion.

Without doing research right now, I am 99.99% sure that the biggest single combustion by product of an internal combustion engine is in fact water..... The hydrogen you speak of combines with oxygen in combustion and thus produces water... H2O... "Thats some high quality h2o coach Kline"
I could be mistaken,,,, but I don't think so....

Im positive, if the air is 100% dry then you wont get ANY water coming out.

But,,,, beggin yer pardon, yer wrong on this one!!
Check it out for yourself....

As stated, water is in fact THE major byproduct of gasoline combustion.
Trust us.
"Octane, a typical gasoline molecule has a chemical formula of C8H18. When combusted in an internal combustion engine the chemical equation is:
C8H18 + 12.5 O2 = 8CO2 + 9H20
As you can see over half of the exhaust gases formed are water molecules (H2O). In a typical vehicle at 60 miles per hour getting 30 mile per gallon the engine is burning up gasoline at the rate of two gallons per hour. Gasoline weighs about 3 kilograms per gallon so that typical vehicle is burning up 6 kilograms of gasoline per hour. If Octane is the typical molecule of gasoline then each 114 grams of octane (molecular weight of octane is 114 grams) produces 162 grams of water (9 times the molecular weight of water, 18 grams). So every hour the typical vehicle produces 8.5 kilograms of water. That equates to 18.75 pounds or 2.3 gallons of water. "
