Seized TEF now has water in cylinder 2

Today I had planned to use compressed air to blow out the Cola I used in an attempt to dissolve any rust in my cylinders. So i removed the diesel injectors and applied the air gun. But in number 2 cylinder all I got was water. Fairly clean water, could this be coming from the cooling system. I have never worked with a wet sleeve engine before and am on a steep learning curve.
The engine is seized so 90% chance the head has to come off, as I have tried every suggestion to free the engine.
 
I don't know the history of the tractor so...

Has it been sitting outside? And now the engine is stuck?
If so, it is probably rain water. If it hasn't been to long, like years, you might get it to break loose and run. But you need to get the water out first so you can get some penetrating oil down into the cylinders.

If it was running, and locked up, or got hot and now has water in the cylinders, the water is likely coolant, and it will need to come apart.
 
Sorry I have no history on the tractor either. i bought it as a non runner, when I pulled the injectors to put in penetrating fluid number two piston had a large amount of apparently clean water in it. i assumed from the vertical exhaust and being stored out side.
I cleared it with air, then appplied atf thinned with racing A.
Two weeks later tried the cola trick to see if rust was a factor, that was more than a week ago.
Can you tell me if water from the cooling system could be getting into the cylinder through a blown head gasket?
I just dont follow clearly the wet sleeve engine system and am still awaiting the manual.
Thanks
 
"Can you tell me if water from the cooling system could be getting into the cylinder through a blown head gasket?"

Yes, it can. That is the most common cause of coolant in a cylinder. Coolant can also get into a cylinder by a cracked head, or a damaged head due to a dropped valve or something on top of a piston has damaged the combustion chamber roof. And coolant can get in a cylinder through a pin hole or crack in a cylinder sleeve, or a wrist pin that has come loose and cut the sleeve.

"I just dont follow clearly the wet sleeve engine system and am still awaiting the manual."

A wet sleeve engine uses free standing cylinder sleeves that sit in machined holes in the bottom of the block. There are oring or compression gasket seals to keep coolant from leaking into the crankcase. The top of the sleeves stands slightly higher than the block surface. The head gasket seals directly to the top of the sleeves, the head holds the sleeves in place in the block.

That said, if you pull the head, you'll need to bolt the sleeves down before trying to turn the engine. Otherwise they will come up out of the block. If any move at all, they will need to come out and be resealed at the bottom.

Thanks for that Steve, I had watched a partial video of a TEA20 wet sleeve replacement on line and wondered why the author went to such trouble to show holding the sleeves inplace with penny washers. That now makes perfect sense.
Am I right in understanding that for coolant to enter the bore it must have come through the side of the sleeve, if the head is sealed around the sleeve top. Or can a blown gasket allow coolant to enter the sleeve.
I suppose that either way doesnt matter, Im just trying to get a clearer mental picture of how it all works.
 
It looks as though I may have mislead you, I got this from anothe source.
I'm not sure how you define 'wet sleeved' . The TEF sleeves aren't water cooled though they do slot into bores and have a thin copper gasket/shim under them. This is to provide a better seat in the block, possible loss of compression into the crankcase and possible oil ingress into the combustion chamber. The only coolant is in the block water jacket and the head..
So it may be that I have a common head gasket leak.
