Excessive water puddling from exhaust muffler

Postby jose.martinez17 [OP] » Jan 28 2011, 7:13pm

Has anyone experienced a puddle of water coming out of their muffler? Condensation is mist, moisture, water drips...I'm talking a puddle under my muffler dripping a drop every 2 seconds. Dealer says that's normal, but i think that's not "Normal"; that's excessive. Feedback?

Must be normal!! mine has dual exhausts.....it drips water on "warmer" days and if it sets there long,they get as big around as steel coffee can lid or bigger.Drips steady til it moves. Never had a problem, and it don't show up in the oil.

Condensation is normal. Ever watch someone pull out on a highway and see a cloud of water vapor come out of their exhaust pipe? When faced with sudden acceleration, the water vaporizes and comes out as mist.

If you are warming up your vehicle while it sits in the driveway, the water droplets will get pushed out the exhaust pipe and form a puddle. If the relative humidity is high, more will be produced than if the atmosphere is dry.

Maybe it's all that water-absorbing gas they produce today that is making it seem more severe!
If you want to do what you want to do, you have to do what you have to do.

John, I think you are on to something. I don't want to highjack the thread, but I suppose it's possible that the higher ethanol fuels may contribute to this. Interesting thought.
Anyway, I am sometimes surprised by the amount of water than can come out of the muffler. I still think it's normal.

Another factor to consider here;When this water is dripping out of the tailpipe...If you can run the engine till this stops,other wise if you put it back in the garage , leave it out , whatever. Tis is when the exhauxt system starts to rust out.I run my 50 merc my 49 convert, and my 32 coupe, all chevy powered . during the winter months.
Its just good to do this, and before i shut any of them off, i put a paper towl up the tailpipe.....no moisture.no rust can form.

I don't worry about the rust. As long as you get the truck out and run it to full operating temp frequently, you won't have an issue. My truck goes about 22 miles each way to work. The exhaust gets fully heated, and the moisture is driven out of it. For comparison, my daughter drives 1.5 miles to school each day. She will definitely go through a muffler or 2 on her car. I encorage her to get out and run it once in a while, but she doesn't.
I don't think I would ever put a paper towel in my exhaust. I am not sure there is a benefit, and I'd be afraid I'd leave it in there the next time I went somewhere.

you also have to look at it like this..on the cold days with the temp of the exhaust vs ambient air temp..it will usually cause some type of condensation
Crap, my hampster fell off the wheel and it broke its leg.
