Blue smoke in both petrol and diesel engines is caused by the burning of engine oil during the combustion phase, i.e there is oil in the combustion chamber. The oil could be entering the combustion chamber via the valve stem seals or the oil rings. Also check that the oil level is correct as too much oil can cause blue smoke Also check that there are no oil leaks that are allowing oil to enter the exhaust system. If all that is in working order, I suggest you pull out the engine and get it overhauled.

What does tractor smoking indicate?
It can be a number of different things. The color of the smoke will often tell you a lot about what's wrong. Generally speaking, with gas or diesel, if the smoke is black, that would indicate that the engine is getting too much fuel. If the smoke is blue, it's probably from engine wear and the color is from oil burning. You can also get white smoke which might mean there is water leaking into the cylinders on a gas engine, and either a cold engine or poor compression on a diesel. There are a lot of other causes and variables. too. For instance, if your engine was getting too much fuel, the excess fuel might seep into the oil pan and mix with the oil. Then you might have black with blue smoke, or just black, or just blue. So, there are a number of things to check.
