John Deere 750 Leaking oil

[Mountaineer Deere]

My John Deere 750 is puking oil out the blow by tube any ideas?

Sounds like cylinder issues. Have you done a compression test and a leak down test? I assume the 750 has an oil filler cap on the valve cover. If so, remove with the engine running and see if you are puking an excessive amount of pressure.

How is the oil level?
Is the oil white/milky?
