I like this MR. CARGUY. The radiator was dry and I refilled it with 50/50. I will add the stop leak and give it a go ....

I don't think I'd do that if my 820 was as nice as your's... If you've got coolant leaking into the cylinder and combusting you'll note the white smoke in the exhaust plume. That's not "blow-by"! Blow-by is the trace smoke coming from the rubber vent pipe on the valve cover.
Even burning very small amounts of water/coolant can result in significant damage to the cylinder head, valves and piston. If the leak becomes big enough the engine could "water lock" and break the piston, a rod and/or the crankshaft. That's a "catastrophic" failure and could mean you sell your tractor for scrap value!
Figure out where the leak is coming from and go from there - IMO.
Good luck.

Yes I would like to know where its coming from too. My first guess would be head gasket and that not too hard to do.

I agree with AKfish.
1. Blowby is combustion gases from the top of the piston into the rest of the engine and gases and a little smoke comes out the vent tube on the side of the engine.
2. Coolant leaking into the combustion chamber produces white smoke out the exhaust pipe.
3. Coolant leaking into the engine oil results in gunk such as your picture and the green droplets you describe. Oil turns grey.
Which of these do you have? Or are you seeing something else? More info the better.

I have all of the above!

Given what you indicated about your experience, I would take it to a trusted mechanic and get it fixed right. I am guessing $2000 to $2500. Curious what others think. Those are very nice tractors and a few K bucks is cheap compared to a new tractor.

I think you have typical indication that your tractor has cylinder liner cavatation from previous owners not changing coolant often enough.I'd recommend pulling engine pan then pressurize radiator and look for antifreeze droplets exiting cyl liners. PS antifreeze is very detrimental to rod & main brgs on crankshaft.

This is what I would do.
Plus in my opinion if you end up doing the head gasket I would look into a full rebuild and clean the whole block out to get all the sludge out. or at least main and rod bearings. The lower end of the motor is the easier part of the project so if the head is off your more than half way there. Its really not as big of a project as you think

Yes tex you are right. Sludge indicates liner and or o-ring failure. Good oils and engine temp. can take care of condensation and water but antifreeze turns to sludge plugs everything. and ruins cranks.

Tx Jim I'm in agreement with you. Have a brother that runs a Farmall"B" clean and seldom burns a pint of gas at one running. Called me that has water in oil not sludge drains water before using . told him this is a probably 0 ring in liner and to not run until locate what is wrong. Didn't believe me because he takes care if the tractor,
Any way went to where he lives pulled pan and #3 liner was dripping. took off the head and pulled liner it was cracked and pitted looked like cavitation in a pump . inside water chamber was enough crud sludge to be able to scoop out by hand .so removed all liners and purchased new bearings and pistons rings and liners for less than 350.00 . engine now runs better than he can remember. All this to replace was less than 4 hours of work.
Told him either work the engine or sell and hire some one to putter around his yard.
Doubt he will do either.
