Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head.
Black smoke from engines on starting and/or running tends to mean there is fuel leaking into the engine, or the fuel mix is incorrect and not atomised correctly. the main causes are normally a nakered air filter that isnt letting enough clean air into the engine to mix. a blocked fuel filter, which is either not letting enough fuel in, or in some cases, a faulty fuel filter which is letting too much fuel into the engine, and causing black smoke due to excess burning. Black smoke is a fuel/air mixture suggestion problems with injection or carbonation. Cause of black smoke is due to running rich in the fuel air mix.
Check the oil,the oil leak,the air filter,the fuel pump and fuel filter to confirm the fault.

SOURCE: thick white smoke coming from exhaust
I would think this will be a blown turbo.
These are fed by a small oil pipe and if the unit overheats (due to wear) - this oil fill feed directly into either the inlet manifold - or the outlet - exhaust.
If it is spilling oil into the hot exhaust - you will get a thick white fog. You can confirm this by placing a clear glass bottle or jar in the exhaust stream - and see if it gets a thick coating of oil on it. If it evaporates - it's water, if not - or feels oily - new turbo or overhaul.
Best get is sortd sooner rather than later - as you may be able to save most of it for an overhaul rather than scrap it if badly worn.

Black smoke from exhaust usually means too rich in gas. Ratio of gas and air mixture. Maybe a dirty air filter, bad maf or map sensor. Good Luck
SOURCE: White smoke is coming for rear exhaust pipe after
White smoke is usually the sign of a blown headgasket.. I would have the coolant system pressure tested before any serious damage is done.
