Did you say you have a gas engine blowing black smoke? Blue is oil, and white is coolant/water most commonly from a head gasket but maybe you already know that.

A bad oxygen sensor often results in a rich mix, which prodices unburned hydrocarbons and black smoke.

 

It also destroys catalytic converters pretty quick, since the converter has to work overtime to try to clean up all that stuff.

it def is black.

Check the airfilter. If it is dirty or oil soaked then it starves the engine for air and thus you end up with a rich mixture. Rich mixture = black smoke and destroyed catalytic converter.
