360 water in exhaust system

dodge1972 · Apr 29, 2020

Purchased a 79 dodge with a 360 with heaters serval years ago. Its been in storage, just start it from time to time. When starting a lot of water or comes out the right side of the dual exhaust. estimate a gallon within a few minutes. What's odd is none out the left side. All engine produce moisture on cold starts, but this one pushes a lot out. Radiator level apears normal, but I really don't drive it, just run it for 5 minutes and shut it down. don't see any water near the engine, just out the right exhaust pipe.

A GALLON....

You're doing more damage starting it up for 5 minutes and shutting it off, I can tell you that. Either leave it sit or run it long enough to be fully up to temperature and burn the condensation completely out of her. Drive the thing!

The few minutes of running causes the condensation to accumulate and when you start it that is when the water is coming out. I have an SRT chally and always run it till oil temp is above 212*. Your vehicle isn't insured or registered to do what your doing. My 71 Cuda is driven at least once a week and I usually put on 20 miles. Of course sun has to be out.

Water is a bi-product of complete combustion. You need to allow the engine to heat up to operating temperature for a while. I typically wait til I no longer see anything coming out of the tailpipes. 440'

It's only coming out of one side because there's probably a heat control valve somewhere that reduces or blocks the other side until it's warmed up.

and I think everyone knows to warm it up good before romping on it. After temp is up to normal operating the oil psi comes down to operating psi. 1/2 hour of driving before hammer time

Normal bro.....

You could have water leaking around a header bolt or stud too, as I believe they screw into the water jacket on a 360.

For every gallon of fuel you burn you create up to a gallon of water through the explosion process. As others have said the engine needs to really warm up to purge all condensation from the system. You can always tell a car that is cold esp in winter cause the vapour coming out of the tailpipe is water condensate. Oncer an engine and its exhaust system is up to operating temp you dont see the water as it has not cooled to be seen as vapour. Its interesting watching movies and the car turns up and the occupants have driven a distance and the tailpipe is still showing vapour - shows the car hasn't run long enough to warm up yet the movie theme will say something else however thats Hollywood for you. You need to run the engine for longer and if possible move it abit as you need to stir up the oil/fluids in the gearbox and diff. I've seen ring and pinions start to rust cause the wheels were not turned and the oil eventually drained off the third member and the hot/cold cycle of the seasons will create some form of condensation. Cars in storage are a hard machine to maintain cause they are designed to move and part of that lubrication process protects steel as a by product. Also I'll presume you are venting the room the car is in well as all of this can kill you via carbon monoxide poisoning Cheers

I see you're from CO so i'm thinking the car is in storage which means it probably is not in a climate controlled building. Are you sure your anti freeze is good, and it didn't freeze up over the winter some time. Have to be careful in cold climates.

An old trick from back in the day is to drill a small (1/8") hole at the back center of the mufflers to let water drain out. I grew up in WI and we did this because especially in the cold temps you ended up with condensation in the exhaust that would't get burned off and caused muffler replacement every 2 or 3 years.

I used to weld a washer when drilling that drain hole to keep the pipe from rusting

AJ/FormS · May 11, 2020

I drilled those holes and one in every low-point of every pipe .............. in 1999, and still running the same TTI, pig-heavy, 75 pound exhaust system. Every time I gas that car up, I think about them 75 pounds; like burning dollar bills.
