Coolant in exhaust

I hate to start another thread about this, but I'm going to...

I recently bought this 96 Disco and it had a visible coolant and oil leak from the passenger headgasket and alot of coolant in the oil. It would run, but power was low and had misfire codes. Nothing out of the ordinary. I pulled the heads and fortunately all the liners looked OK. I replaced both headgaskets and intake gasket, changed oil and coolant. Now engine runs fine, no codes, no exterior oil or coolant leaks, but I still have steam coming from the exhaust. All plugs look OK, so I can't identify any particular cylinder having a problem.

How else can coolant get into the cylinders? Cracked head? Internal intake manifold leak?

Thanks,
Stephen

Doesnt sound unusal. There is always some water in your exhaust. If you only have water coming out, and nothing else usual... I would say your just looking for trouble.

I know the normal condensate expelled from the exhaust. My Classic does that untill it warms up. It's not that. After driving for 30-45 minutes, it still does it. It starts just after start up and increases with engine speed. If I'm driving, and let off the gas, I can see it out the back window. It looks just like a car with a blown head gasket.

Water in the exhaust system was my first thought too, but I would have thought it would go away after a few minutes. How much water could be in there?

It does use coolant, but just a little.

The heads were cleaned and checked for true.

I've done a few heads before, but not had this problem before.

I have not owned this one for very long, so I don't know if there was an existing problem. I just saw the oil and coolant leaking out from the heads. I knew that needed to be done.

I was hoping someone else had seen this problem before. I can't figure out what else could be causing it.

Thanks for the help.

A product of combustion is water. About how little coolant does it use and how much smoke do you see? Have you pulled the plugs and looked at them?

Ron-I knew it wasnt a dropped liner, I just did the headgaskets and the liners looked OK. I've never seen a cracked block. I thought it could be a head. Wholesale it? I bought it for $400 knowing it needed at least headgaskets.

PT-I think you hit the nail on the head. I guess that the previous owner ran it and put a bunch of water in the exhaust. The muffler must have been full. Plus with it being cold and damp outside here-that made it worse. It finally quit after running for about 2 hours. The coolant reservoir was leaking at the seam on the side next to the fuse panel. I thought it was just overflow from when I filled it. I don't think it's using any coolant now. Thanks for your help.

Get that fixed sooner rather than later. It'll only get worse; the system won't hold pressure, and coolant will get lost through the leak whenver it gets warm enough to expand up the the leak; eventually you lose enough so that overheating is a potential concern.

if it hasnt been said above

i had a head leak (coolant into cyl into exhaust) for a while.
after repairing it it took even longer for it to dry out of the exhaust system.

seems to hang around in there for a while.
