water in exhaust???

I changed my oil this afternoon. While it was up on the ramps, I started it and let it run for a few minutes. While looking underneath for leaks, I saw something dripping from the rear of the vehicle. Upon inspection it was a bit of water dripping from the tailpipe. Obviously it was "flowing" a little more quickly because of the angle, but still enough to concern me!! Is there something wrong???

no most car's have water in the exhaust i had my 92 runing to end it had water comeing out of the exhust

thanks beavis! I was hoping that was the response I would get:)

your welcome when it's cold out you get more water come out of the exhaust

the reason is because the CC works harder in the winter, since cars burn richer when cold, and the cold weather means they take longer to lean out - the CC converts NOX and CO into Water...

as long as you aren't getting anything that looks like white smoke, it's normal - white smoke is a different story...

I would say it's just condensation. It is more prevalent in cold weather due to the exhaust being much warmer than the outside air causing the extra condensation to form. As long as it's not coolant (no sweet smell or color to it), I'd say it's nothing to worry about.

yeah, true, but the Cat is working a bit harder as well in any car when the temp drops.

Correct, white smoke indicates that you have a coolant leak into the combustion chamber somewhere... if it's normal gray, etc - no worries on any water there

HC and CO (hydrocarbon and carbon monoxide) are processed by the cat, breaking hydrogen atoms from HC and combining with oxygen cracked from the CO bond, to form water (H2O) and carbon dioxide (CO2) which is inert. NOx is broken into nitrogen and oxygen, both harmless. But the visible output is water, and a bit of leftover carbon...

The cat may work a bit harder in cold weather since the engine stays in a cold rich mode a little longer but once full operating temp is reached, cat operation is normal. The reason you see more condensate is because the colder exhaust pipes when you start the motor instantly condenses the water being produced until the pipe has warmed up all the way to the tail pipe...normally that water would make it out of the system as vapor, but in cold weather it condenses and pools in the system...there is a small drain hole at the bottom of your muffler, most will run out there. It has to either run out or get cooked out by exhaust temps after warm-up...Car that don't get driven much have a lot of condensate in them, which is why old lady cars that don't go anywhere very far or very fast always have mufflers that rust through prematurely...

come to think of it, I remember talking to the guy who does my exhaust work about that little hole. I thought it was a rust hole forming; he then informed me that it was supposed to be there to let any water in the system run out, preventing premature breakdown of the muffler. Thanks for the responses!!
