No rain overnight, definitely came from the radiator through the block into sump. Disconnected the water pipes to cooler and tried to blow in one pipe while holding the other closed, no air leaking out anywhere. We thought of every other possibility, but nothing makes sense.Had you rain overnight, was it outside?
Don't rule out the cooler completely, if unsure can you bypass (join the coolant pipes) to test?
Lots of rust, thinking some rust got behind o-ring and broke itCould the liner have been moving up and down very slightly with the slack head bolts, causing the o ring to fail?
dont worry about rings and bearings if its not knocking or breathingI haven't priced a new one from the local Deere dealer yet. But it'll take another week to get here probably. Neighbor has same tractor that they overhauled engine recently, going to see if I can't use one of his old sleeves. Should probably replace all of them, plan is to put new rings and bearings in it then as well. Just don't have the funds to do it right now.
Probably poor quality water in it too. I'm sure they all will look like this one.thing is its had no antifreeze/inhibitor in it thats why its rusty
the other 3 liners will look the same
could you get that 1 sandblasted clean to inspect it?
Do you know anyone sh!t hot at welding,preferably TIG?Probably poor quality water in it too. I'm sure they all will look like this one.
The liner doesn't look too bad overall, just that one place where the o-ring sits that bothers me. I'm worried it will not seal properly and leak again. Could I chance putting a little silicone there?

They could build it up quietly and dress it back for now as temporary fix
Hence low amp tig and a good welderWhat about the rings, would you not be afraid of the cylinder going oval with the heat?
