Why is my grand vitara 2.4 LItre engine puffing smoke after moving from traffic lights
it is an intermittent problem with a grating sound. The puff of smoke is so huge at times,
sometimes the vehicle behind stops to avoid it getting into their vehicle
Black smoke means unburnt fuel, blue smoke is burning oil, white smoke is water vapor possibly head gasket problems.
Replace PCV valve and it will be fixed
