the risk is small, but it's there. a diesel runs on higher compression, and you'd think some water wouldnt hurt. i've seen several diesels throw a rod or blow the top off the power assembly, from a leaking water jacket. (emd locomotives) i've also hydro-locked a diesel, trying to crank it, with water in the cylinder. bent a rod, but didnt break it.
i use an empty dish detergent bottle, and just drizzle it, in a really light stream, with the motor at a very high idle. maybe 2000-2500 rpm. you'll know you're adding too much, when the motor starts to bog down, as it fights to compress the water. i also have the car hot from driving before doing this, or you might fill the mufflers with water and crap, helping to rust/clog it.
the gas today is a lot cleaner (some of it's clear, like water, vs the dark orange stuff we used to pump) and as long as your guides arent leaking, and you dont just idle the motor endlessly, it shouldnt be all that dirty. once or twice a year should be fine, if you worry about deposits. if the plugs are clean and dry, i would imagine the rest of the combustion chamber is, as well.
That's the problem, this motor has not been run much besides idling for the past 4 years. There has been no "punching it" so that's why I cam guessing this should be done.
Thanks for the help!

If the car is just dieseling, I would check the timing and/or idle mixtures. The rest of the info on cleaning stuff is good none-the-less 
If you ever find yourself in a fair fight, your tactics suck.

I have seen a running motor bend a rod due to water ingestion  As already suggested put new gas in it and drive it for a long trip to warm the oil up and suck out the bad gas that is in the tank. That or drain the tank, put all new fuel in it and then drive it for 50 miles or more   I've done all the old school stuff down the carb, a water and alcholol injection system will help clean the combustion chambers if you absolutely want that done   One thing you need to remember about all the old school methods, that was when all gasoline had lead in the fuel  Lots more deposits in the motor and exhaust sytem then than now, also keep in mind that those motors ran under 180F on a hot day, not like todays motosr runniing EFI and over 200 F to keep them effecient by atomizing the fuel better Don't pour any water, oil or ATF into the carb

ATF has to high of a flash-point... Use something like Marvel Mystery oil or some 2 stroke oil...

If you are wanting to clean the combustion chambers, then there are some very good products just for that purpose. And they work much better than water or ATF or Diesel.
It's called something like combustion chamber cleaner or upper cylinder cleaner and is available at a lot of places. Boat shops use it all the time. I keep some of GMs upper cylinder cleaner to clean carbs with. Works better than carb cleaner and is water soluable.
This is the same stuff that JC WHitney used to call Tune-Up-In-A-Can. But it works very well. In fact, the outboard service schools recommend these products as the preferred choice to clean their carbs. So I have used this stuff instead of carb cleaner for 20 years. Seems kind of funny that a product that is designed for and does a good job of de-carbonizing combustion chambers is not very well known.
As to the question of whether that is the root of the OPs problem, well, maybe, maybe not. But it doesn't take much time or money to clean the combustion chambers and at least rule it out.
Master, again and still

We used to use the cheapest pump spray glass cleaner (cheap Windex). It's mostly water, alcohol and dye. Warm engine, put on highest fast idle - about 2500 and spray it in about as fast as you can squeeze the pump without stalling engine - use about 1/2 the large bottle. Take off fast idle, spray in and stall engine. Let sit for 10-15 min, re-start, and run at about 2000 for about a minute. The nice thing about doing it this way is you can control the liquid better without having to worry about locking the motor up.
Free advice and worth every penny...

Mopar Combustion Chamber Cleaner - unless you live in California where you can't get it anymore - so it must be good!
I have a feeling it's relabeled Seafoam.
diesel will do the same thing only cheaper. You guys using water may as well leave all your condensation in your gas tank and oil - hell all it is doing is flushing & cleaning our oiling and fuel systems.

..neighbor told me GM had service bulletin instructing the use of ATF to clean and free up noisy lifters.
Been doing that for many years and it has been stated many times her e too. Ad a few miles before and oil change. ATF has very high detergent content. In fact if you have dirty grease cruddy hands dip into some ATF and rub in like GoJo and they will be just as clean.

BG induction cleaner sucked through a vacuum source at the base of the carb that has constant vacuum.Do one can then take it out and get it warm and then repeat one more time.
