Water from Exhaust??????????
 
what the hell. I was doing some idle adjustments today, and while under the hood I decided to retard the timing a little bit, which has caused my car to smoke even more!!! I guess it is possible for a new engine to have crappy oil seals, great that isn't embarrasing or anything, but

as I was in the driveway, I noticed little puddles at my tips, there are little drain holes in the tips and there was actually a 6 inch round puddle after like 10 minutes. Why would their be water coming from the exhaust. The smoke thaat comes out is oilly not coolant. Coolant level is always good, plus I know what coolant smoke smells like.

I don't understand what it is, please help me..Thanks

Well one of the by-products of cumbustion is H2O so you might just have a lot of it. lol

You could have had water in the pipes afte the drain hole and the cars exhaust might have pushed it out.

That's quite alot of water, but not unheard of due to long idle periods. To be safe, presure test the cooling system or do the "bubble test". That will tell you for sure if you should worry.

what do you mean bubble test? I have checked the coolant level and it hasn't gone down. I ahve never seen this before on my car.

turn on the car with the rad. cap off. see bubbles?

wpgrexx 10-01-03 03:04 PM

oh, you mean is the system bled off, yes, with the heater on full tits.

No, that's not the bubble test.

With the car completely cool, remove the coolant filler cap. Now, start the car. Look into the coolant...do you see a steady stream of bubbles coming from somewhere in the engine? Rev the engine via the lever on the throttle body. Do the bubbles increase or does coolant gush out? If yes, then you may be looking at a coolant seal failure. Do a proper pressure test to be absolutely sure.

Note that the entire time you do this procedure, the car cannot be warmed up.

I don't think there's anything to worry about. Water is produced as a byproduct of combustion. The more efficient the combustion the more water that is produced.
