I have a question ? recently bought a 1978 GMC Eleganza II and when I open the RH hood ( for lack of better word ) I can see the radiator and where you add radiator fluid, but there is another cap ( well my cap is missing ) or another what looks like a radiator fill line ? Is that what it is or is that a fill port for something else ?
Thanks for any help you may be able to provide !

That will be hard to flush as the oil pan has a front recess to clear the drive shaft that holds 1 QT. Don't run it with antifreeze in the oil as you will ruin the bearings.
Ethylene glycol goes in the overflow jug. The radiator cap should stay fully on for normal adding.

I added about 12 oz of water out of water bottle,,, don't ask me why just seemed like the thing to do at the time ! and before I thought I better look into it before I add any more !

I will have to go back and look in the morning , but I do believe it is the one when you open right side hood and it is almost center up front and yes has a long tube running back toward the engine, I'm missing the cap and with it gone assumed ! It was for the radiator until I looked a little harder and saw the radiator has one located on it as normal ! I can take photos and post tomorrow if that will help ?
I know I need the help !!

Sir, in your case there may be another cap like that in the propane compartment. It is for potable water. The operators manual for your coach is required reading. The front oil fill cap is from a Toronado your year model I believe.

12 ounces of water - not antifreeze - ain't the end of the world, but it must be got out to the degree it's gettable out. If one of the gurus here has an idea, I'd follow it. Otherwise, I'd go get a couple gallons of the cheapest motoroil I could find. Pour a gallon through, out the drain into a clean pan and see how much water came with it. Keep this up (you can reuse the oil to flush) until you aren't getting any more water out. If you got most of it, then clean oil, new filter, fire it off, and get it up to running temp to evaporate whatever's left. change the oil and go about your binniss. If you don't recover most of the water, there's a problem. It can be dissolved in alcohol, and that mix flushed as above... but the alcohol will also wash loose whatever crud it contacts on the way through. A gallon of alcohol run through (as with the oil flushing, remove the drain, put a clean pan under and pour it through). After the alcohol, the oil flush again, then new oil and play Dirty Harry (How do ya feel, Punk? Lucky?). The option is to remove the oil pan, clean it, and put it back, which will get the water out, but it's a PIA to accomplish.

Glover,
Before you do any else, do download the manuals that Rob has given you the short cut too. Get an oil cap, NAPA# BK7031692, under $3.00. If you want something in the bling style. http://www.jegs.com/i/Spectre/865/43105/10002/-1

Brian,
Welcome to the GA GMC family! You should have let us know you're here.
There are current and former skilled GMC owners near you, one probably not
10 miles away, and I'm not very far away, in Americus, just one turn away
after you get on US19.
I'll second the recommendations you've already gotten, with some additions;
Jack the front of the coach as high as possible so the drain plug is as
far below the front of the pan as possible. If you look at this album,
you'll see where you're trying to remove water from:
http://www.gmcmhphotos.com/photos/g3942-455-oil-pan-capacity.html
The front section of the pan, which holds 1 qt. of oil, is where most of
the water you poured went first. Since H20 is heavier than oil, most of it
probably stayed there.
You should capture all of the material you drain from the pan, catching the
first of it in a clear 1+ gallon container. You want to be able to see how
much water is below the oil after the mixture has had a chance to settle.
If you're lucky, most of the water will NOT have stayed in the front
section but will be in the container now.
Now pour that cheap-as-you-can-find oil through the engine repeatedly
(there's no need to install the drain plug), always catching it in the
clear container and checking the amount of water after the mixture
settles. When you don't collect any more water, you should be safe to
install 5 quarts of the cheap oil and run the engine up to normal
temperature; I would not drive the coach yet. Now drain and check again
for water. If you still see any, drain the oil off, leaving the water
behind, and repeat the fill & run again. Keep doing that until all the
water's out. Now you can fill with your preferred regular oil, probably a
15w40 dino oil. You've dodged a bullet!
Go to www.GMCDixielanders.org. Join the club, and sign up for the November
rally at Pensacola -- we'll be expecting you.
Give me a call at 229 nine thirty-eight 27 ninety-seven if I can help in
any way.

Simply noted - it's a PIA. However, had there been glycol in the water he added, that would be the only option.

You can always use a small hole saw in the front part of the sump to drain the oil and flush then make a bonding patch on the outside.

Since we are talking about antifreeze getting into the oil pan keep in mind anyone that is about to replace the engine driven water pump with a new pump. You absolutely need to first drain the radiator then both sides of the engine block. If you don't do this when you unbolt the old pump some coolent will flow into the oil pan as the timing cover will pull away from the block about 1/8" leaving a path for the Coolent to flow into the oil pan. This is for sure if you use a non hardening sealant on the timing cover like permatex. It happened to me and I was glad I had a 2nd drain plug in the pan as several ounces wound up in the front sump.
