Okay, I have a puzzling question. What would cause water to be present in one exhaust pipe?

The car has been sitting for a while, and the other day I started it, and water shot out of the passenger side exhaust pipe. Im not talking a little condensation, but a good amount. I ran the engine for a while and it seemed to clear up. Two or three days went by, and I restarted it again, and had the same thing happen. Now the exhaust exits in front of the rear tires, and it was parked backed in to the parking spot slightly on a rear raised angle. I figured the first time, that rain may have gotten into the pipe, but after seeing it happen again, I doubt it. ould this be a blown head gasket? Cracked head? What is it?

The water(condensation) it a byproduct of combustion, it was probably there during the warm weather but you didn't see it and as the weather has gotten colder,it takes longer for the exhaust to heat up to boil the condensation away.

The thing is, I had ran it the other day, ater changing a freeze plug, and adding an aluminum radiator. After that I ran it for a good hour, checking the temp and looking for leaks and such. All is well with the rest of it, except for the initial start up, which shot out a good amount of water. That was 3 days ago, and yesterday I started it up again to let it run for a bit, and the water again shot out of the passengerside pipe. If this is from condensation, why the heck wouldnt it be present on both sides? For exhaust, all I have is headers, header mufflers (glass pack types) and shorty pipes for exit in front of the rear tires.

If you don't have oil in your antifreeze or antifreeze in your oil, and your radiator stays full, I would have to agree with Leo. I don't know why there would be more on one side. Drive it for a while if the oil/coolant is fine, put it on the highway for a long run and dry it out.

Is the little drain hole in the muffler plugged on that side? Or do you even have water drain holes in your mufflers? Your muffler is probably full of water on that side of the car.

I had no clue that mufflers had drain holes at all. No, these are Cherry Bomb style tube type header mufflers. No drains. Im going to redo my exhaust anyway, so I will find out whats going on.

I know the mufflers on my new car have drain holes from the factory. I'd never seen them before prior to that, but a quick solution to the common problem of mufflers full of water is to use a hammer and nail and drive a small hole at the low point in the muffler.
