My car is smoking sometimes. The smoke is white. I had the head gasket changed last year around November. I also gutted out my catalytic converter, because that was all clogged up. The radiator fluid seems OK and the oil is not a milky color. I know white smoke is bad. What can I do to fix this problem? Thanks

 

its either running rich or is burning oil, i cant remember which color is what.

 

if its white... he isnt burning oil... white is either water, or he is running too rich

 

leakdown or pressure test the system would be were I would start if nothing looks to obvious.
