the black liquid is most likely oil and the smoke indicates the rings are bad or a valve is sticking allowing oil into the cylinder.
you are most likely looking at an engine rebuild
p0302 is a misfire in cylinder number 2 white smoke could be from coolant so if the head gasket is blown coolant can leak into the cylinder and cause the misfire are you loosing coolant that might be where its going
are you sure that it is smoke ? it may be steam which would indicate a blown head gasket or cracked head, usually if the engine is getting too much fuel the smoke is black & if it is burning oil it is blue, if it is steam it will dissipate into the atmosphere very quickly, but blue or black smoke will linger for a while, you need to be certain exactly what it is before you can take any action to repair the problem......hope this helps......cheers.
If there's a black smoke coming out of the muffler then have the o2 sensor replaced. The air fuel ratio has irregularities and by replacing the o2 sensor the problem can be resolved.
Hope this helps and thank you for using FixYa! Have a good one!
One potential cause is too much gas. It may be running "rich". Your car
may also be burning a little oil. White smoke is water or antifreeze. If you are loosing coolant from the
radiator, it's probably a blown head gasket. If not, it is just
condensation in the exhaust pipe that is evaporating as the pipes heat
up. If the car is running too rich, the unburned gas will cause black
smoke and burning oil smoke will be blue.
If the black smoke comes out of the muffler, you are burning excess fuel and could have an air filter plugged up to restrict air intake and cause the engine to run rich, therefor black smoke.
Well is the smoke coming out the exhaust BLUE or BLACK if Blue then its due to engine burning oil ..ie,,Piston rings /Valve seals etc etc
If Black then its fuel to much fuel going in engine and not being burnt.
So let me know more infomation and what colour smoke it is then we can get the problem sorted..
