It needs a ring job. Which is something done with specialty tools so a mechanic is the best bet to have this fixed.
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.
white smoke indicates a blown head gasket. Is your car using one quart of oil a week?
A miss, black smoke and a strong gas smell. Also, bad acceleration, rough idling, and stalling.
A faulty turbo is indicated by pure black smoke when engine revs are above idling revs and it can also be shown by poor machine performance.
Black smoke from the exhaust and rough idling are two of the more common problems. The egr valve can be removed and cleaned on most vehicles
a dirty air filter or a dirty fuel filter will cause a diesel to smoke
What color is the smoke? Black - running rich. Bluish - buring oil. White - burning coolant. When you smell the gas, it is inside or outside the minivan? Back of the car or near the front?
Black smoke is caused by an over rich mixture and normally occurs whenever the engine is working hard. Like going up a steep grade, being loaded heavy or during heavy acceleration. More black smoke can be observed when the vehicle is operated at higher altitudes because the air is thinner. A dirty air filter is also another cause of excessive black smoke. If black smoke is noticed while the engine is idling at low altitude or under normal driving conditions this condition should be diagnosed a.s.a.p. to prevent engine damage. bad rings or busted pisten you need anew motor
Black smoke is soot, particles of carbon.It forms due to a shortage of oxygen preventing full combustion.Some occasional black smoke is normal in diesel engines, especially when under heavy load (e.g. rapid acceleration, climbing hills).However a gasoline engine should never produce black smoke! The most common cause of black smoke in a gasoline engine is oil leaking into the cylinders and burning, the most common ways oil enters the cylinders are a blown head gasket or damaged piston rings; both of which are very serious problems which will likely be expensive to repair!!!
It is not meant to smoke. It is running properly if there is no black smoke.It is not meant to smoke. It is running properly if there is no black smoke.
oil is leaking into combustion chamber
It looks like a mountain with occasional smoke coming from the top
