That is really a "suggestive" subject...!! It depends...some tractors will "Breath" quite a bit, until they are really good and hot--as they are eveporating moisture from the crankcase, etc.. If it is still blowing a lot of vapors after a good long hot run, suspect ring-seal, or valve-guides..
Using a "Leak-down" type compression tester will give you a good idea of each cylinder"s condition.
Using this method, you can actually hear any leaks from the intake valve, exhaust valve, breather, etc..
What you use is regulated compressed air put in the cylinder at reduced pressure, while the piston is at TDCC..
With an air-flow measurement, you can see how much is leaking out of the cylinder..
Less than 10%leak-down is pretty good..1 or 2% is what you would want in a competition engine
BUT..if it still runs good...why fix it if it ain"t broke..???
