Black smoke is a sign of engine overload, a restricted air supply, or a malfunctioning injector. For some reason, excess unburned fuel is being blown out of the exhaust.

On a newer vehicle with fuel injection, black exhaust smoke can be caused by one or more leaky fuel injectors, too much fuel pressure (sticking fuel pressure regulator), a faulty MAF sensor or Oxygen sensor, or a engine computer fault. with diesel engines,black smoke in the exhaust can occur during hard acceleration.
The first things you should check are your air-filter and other intake components like sensors, fuel injectors and the fuel-pressure regulator. Other reasons could be a clogged fuel return line.
I presume you are adding oil (topping up). If you are then you have a series problem with piston ring wear inside engine. Oil is getting past the wiper rings and getting into the combustion chamber and burning with the fuel. Need to rebuild or replace engine.
black smoke usually indicates to much fuel being delivered. If this is the case you need to correct it soon or you will damage the catalytic convertor. What year is the vehicle and how many miles on it? Is there a check engine light on? this info would help
Generall black smoke indicated the burning of oil. This is due to oil slipping by the rings. If the rings are allowing oild to slip by then you will have poor compression which translates into no power when you put your foot down. IF the rings are bad you are looking at a rebuild. Probably cheaper to buy a replacement engine from a junkyard. The definitive test is to have a compression test performed
Hi , if you have had a turbo failure on this vehicle , just replacing the turbo will not cure the cause of blue smoke . depending how bad the seals had gone in the turbo you would need to replace , the complete exhaust system , the crankcase breater , air intake manifold , air charger but only if these items have been contaminated with oil , they would not be able to be cleaned out , hope this helps , regards mark
It is Starting to Burn Oil But, Very Little. Sometime Down the Road you will need to get the Rings in the Motor Replaced to Stop this Problem. Please Rate My Response! Thanks!
