The O2 sensor is played out. Do your self a favor. Replace all of them at the same time.

Agree with boholmark,all so if it is burning oil,may not hurt to change your plug,s and add some oil fouler,s to help prevent plug,s from fouling out from the oil.

Black smoke is unburnt hydrocarbons GAS --white or white/blue tint is oil ..it's running very rich, the 02 sensor is not sending the correct data to the ECU to set fuel/air trim ...a 14 year old sensor may be simply worn out

Yep replace the O2 sensors, they are telling the ECM that the engine is too lean so the ECM is increasing the fuel mixture thus the black smoke, but the o2 sensor are so far gone that they don't see the mixture increase so the reading don't change. Got it?
