hmm, not sure, but i dont know how there could be that much, there is alot of it. i recorded it and it should be on youtube in a day or two

yeah, i would also say its moisture. If it was gas i dont think your truck would be running. You'd have some extremely fowled plugs also...

i guess your right, what would be causing so much moisture?

When the exhaust is hotter then the inside surface of your exhaust system, you produce condensation. combine that with exhaust gases that slightly cool and you get more condensation.

no, it looks clear. there is just alot of it. i thought it might be gas because i dont know that much about engines

So.Cal.Super · 05-08-2009, 02:42 PM

could be black due to oil blow by or carbon build up? mine is clear.

sjarrett71 · 05-08-2009, 03:38 PM

Sounds more like condensation to me too. Does the liquid smell like gas?

gintaras · 05-08-2009, 03:49 PM

hey that's not gas, it's your muffler fluid leaking

all kidding aside, it is just moisture, all cars do this.

but one way to be sure, smell it, taste it, it's just water

I hope you were kidding on the taste it part also, because its far from consumable.

The only engine that makes drinkable water is a hydrogen engine.

Our internal combustion engines will leave deposits of fuel, carbon, oil, carbon monoxide.... I hate to sound like a Green peace member but please do not drink it.

Or we will all suffer from some new Flu Strain... lol

yes... no drinky drinky the water

gintaras · 05-08-2009, 04:18 PM

I would think it would go without saying not to drink a glass of it, but a little taste from your fingertip won't hurt you.

So.Cal.Super · 05-08-2009, 05:11 PM

true, I probably have drank more vehicles fluids on accident. I still wouldn't taste it on purpose.

ZombieWeinerDog · 05-08-2009, 08:59 PM

**special-K** · 05-08-2009, 09:07 PM

Why taste?Smelling will tell the story.
