Ring job versus total rebuild

I've got an old 1956 to35. It's burning oil terribly and tends to be reluctant to start if I turn it off and try to restart it when it's hot. What are the chances a ring job would solve the problem decently say for maybe three to five seasons? Is it like putting a Band-Aid on a broken arm?
 
Part of the answer to your question depends on your answer to this. Do you have good oil pressure at hot idle?

If you have good oil pressure it suggests but does not prove that you main and rod bearings are OK. The next question requires you to remove the head to check for cylinder wear. If it is badly worn, rings won't help much. If minimal wear, then rings alone will help a lot. My Ford 3600 was buring oil like it was free. I just replaced rings and it went from using a quart a day to so little I can't see any difference in 100 hour of usage.

If you can do the work yourself I'd say it is worth the gamble if you have good oil pressure.
 
It's been done many times.

You can do what's called an "in frame overhaul", where you replace the rings and bearings, maybe the oil pump, get the head worked.

That engine has replaceable cylinder liners that just sit in the block. If it's in the budget you can buy new piston/ring/liner assemblies, which will get you pretty much a complete overhaul, "IF" the crank is in tolerance.

The only thing you can't do inframe is replace the rear main seal.

Back to the cylinder liners, being they only sit in the block, with the head off, they need to be held down with a couple bolts and washers.If you don't they will ride up, breaking the oring seal at the bottom, causing coolant to leak in the oil. It's somewhat of a gamble not replacing the orings as they are old and hard anyway. Quite a job cleaning out the water jacket, but the seat area must be clean for them to properly seal and sit at the correct height.

As per suggested...ensure LINERS do NOT MOVE..........

Hone it with a dingleberry hone. Rings and rod bearings,and while you are there check the mains
too.It will help and you may get several years running out of it. I had guy that made me(it really
needed liners and pistons)do a ring and bearing job on a hard working 1080 MF. Two years latter it
was my fault because it was still using massive amount of oil. If I remember right, it had a lot of
cylinder taper.
 
If the taper in the cylinders is under .006 ring it. I'm pretty sure your tractor will not be put in the field and worked hard for hundreds of hours a year.
