The blowby could mean needs a ring job, or a bearing fix, maybe a head gasket. Or that the engine will run another 5000 hours like that -- all diesels have some.

There is so much blow by that it will blow all the oil out. No water in oil, no leaks any where else. I thought it my have another vent somewhere that may be stopped up.

You'll be getting parts from a JD dealer anyway, so that would be a place to start. If you google "tractor [or Deere] manuals" offers will pop up but I don't know the quality. ....
