Fault cause: blue smoke is due to internal engine failure, causing oil fleeing into the combustion chamber to produce, and there are two common situations: the cylinder wall scratches, bad or valve piston seal at serious wear and tear, will have a gap, the engine oil at this time would be fleeing into the combustion chamber through participation in burning, not burning engine oil discharged outside the vehicle produces a blue smoke.

Troubleshooting scenarios:
1 For the older age of the vehicle should always check the tightness of the cylinder, piston and other parts, found time to the service station to repair blue smoke when discharged, to prevent greater losses.
