Futian Ouma truck has insufficient power, high fuel consumption and high blue smoke emission?

When the engine is running, the exhaust pipe emits blue smoke: it is because the engine oil enters the combustion chamber: when the engine fails to burn at low temperature or under small load, it emits blue smoke. However, when the engine temperature rises or the load increases, the oil vapor burns, showing dark gray smoke. The reasons for the above phenomenon are:

(1) Poor air intake: the oil in the supercharger is sucked into the cylinder for combustion.

(2) Too much oil in the oil pan: the oil exceeds the maximum limit.

(3) The valve guide tube feeds oil.

(4) The cylinder leaks oil seriously.

(5) The rotor shaft of the supercharger is seriously worn, and the oil baffle ring is damaged, resulting in the supercharger not reaching the rated speed and leaking oil.
