Thanks for all that have chipped in. Here's a little background on this. The motor started shutting off when it got up to normal temp, I'd have to wait for it to get stone cold again before it would restart. I did the key thing and it showed no ignition from coil, I replaced the coil, same thing happened. Then the dash blinker showed no egr signal, replaced the egr, didn't help. Next the dash blinked no signal from cam sensor, I was getting fed up with chasing things so I took it to a local shop, they replaced the cam sensor, no change. They then put it on their scope and told me it was a bad computer so I had them replace it. They called me a week later and said the truck was fixed. When I went to pick it up the exhaust was steaming (it wasn't steaming before they worked on it). They told me the steam was due to excess fuel in the exhaust system caused by the bad computer. I took their word for it. I trailered the truck home as there are no tags on it, I just use it for plowing my road. When backing it into the garage, the motor warmed up and shut off just as before. So now I have the same problem as before and now also dealing with the dripping tailpipe.

Here's one way to narrow it down a bit, remove all the spark plugs, have someone crank the engine over while you watch to see which spark plug hole is spitting antifreeze. This way you'll know which head to pull. You may have to put a pressure tester on the radiator while doing this but with the way antifreeze is coming out the tailpipe you probably won't have to.

To answer some of your questions, the body is in good shape and yes, the motor is buried under the cowl overhang. I am wondering what they could have done while changing the cam sensor that would cause antifreeze to get in the motor? The cam sensor is in the distributor, behind the giant intake manifold and you can't even see the distributor. It doesn't look like they removed the intake to replace the cam sensor. Do you trust the shop that changed the sensor to tell you if they pulled the intake or not? I could see the intake being the cause of coolant in the oil but it would be a stretch for it to find its way to the exhaust from there. I suppose it MIGHT be able to migrate from the water ports at the front and back of the manifold/cylinder head to the #1, #2 or #7, #8 intake port but that would be a perfect storm kind of scenario to have a gasket breech that much distance without it leaking visibly elsewhere. I don't know if it's possible for the intake to crack or perforate into the plenum from corrosion but that's unicorn territory too I think. Have you pulled the plugs yet? That much coolant on the floor from the exhaust is going to show on the plugs. If it shows on one of the 4 corners you might have a faint hope of a cheap intake gasket swap fix but in any case it should point you to whatever hole is causing the problem and which head needs to come off. The bucks down solution at that point I think is a trip to the local pull your own auto recycler on all engines for $199 day. Kevin

Okay, I did as you guys said. Pulled the spark plugs, I couldn't really tell which one looked steamed. I had my girlfriend crank the motor over, number 8 sprayed A/F all over the inner fender. Looked into the hole with a light and found this (see pic). You can see the A/F thru the #8 spark plug hole. I found a running 5.9 for $550 and decided to just replace the motor. The shop that did the other work said they would cut me a break on installing it. Oh, they said they didn't remove the intake before and I can tell they didn't because the intake bolts were never touched.

Use exactly as the direction say, it is not at all like Barrs leak. Might get lucky and fix it...permanently. I have done it twice after my mechanic friend suggested it to me years ago. It is made for these kinds of situations. LINK

If you were to disconnect the O2 sensor it would run open loop if it will run at all. You could try that to see if it will stay running long enough to get up to and stay at operating temp. I would bypass the heater before I ran that sealer thru it if it's made out of what I think it is.
You sure once it warms up that the AF leak isn't opening up to the point that it's hydraulic locking the engine, making it quit? Looked like a lot of green in one of those pictures you posted.
Kevin It's not locking the cylinder because the motor will crank over easily, just won't fire. Should I disconnect the downstream 02 sensor? The pic is after it sat overnight.

Here's why the K-Seal wouldn't work, this head gasket was really out of shape. Head wasn't cracked.

Well at least it's a cheaper fix. Not easier though.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

With the way it pushed that fire ring out the top of the cylinder it might be a good idea to put a straight edge along the top of the deck and check how far down that piston is compared to the other cylinders. You may have bent a rod.

You may have bent a rod. GC340 your right, I checked the pistons, the other three are .050 in the hole and this one is .090 in the hole. I guess there's a bent connecting rod here. Thanks for having me check that.

I've heard about those super secret variable compression engines, I didn't think they put them in a truck but who knows with Mopar! Ha, Ha.
