If the actual engine is smoking I would look for obvious leaks. I had a car that was leaking oil out of the valve cover and onto the alternator which was creating a smoking condition.

My kia 2700d throws out a lot of smoke especially on an incline when accelerating, but does not smoke when travelling on a level road.


Smoke from an engine that is accelerating is a sign of bad rings on the piston cylinders. Check the color of the smoke and if it is blue then you have that problem.

Why does engine run rich at times under acceleration?


not enough detail
to get an engine to accelerate , the air /fuel mixture is moved to rich in accordance with engine rpms
the more rpms the richer until the peak rpms are reached
( accelerator pump-power valve in carbies and ECM settings according to accelerator position
black exhaust smoke in diesels
so if you press the accelerator slowly then the air/fuel mixture is altered constantly in relation to the pedal setting
If you floor the pedal then it moves to rich and you get black exhaust smoke until the air mixture is again in balance

White smoke out of exhaust


Does it smoke all the time or just when you accelerate? If it smokes all the time, the piston rings are worn. If it smokes when you accelerate and diminishes then the valve stem seals are worn. Either way, the engine will have to come out to fix it.

I changed my engine block and replaced the rings and bearings but the car is smoking and using oil


  • Smoke and abnormal oil use means the car is burning oil.

    If you get smoke when accelerating hard (eg from rest or in high gear when overtaking) it means the oil is getting past the piston rings which indicates worn bores, pistons and/or piston rings.

    If the smoke appears after an over-run* it points to worn valve guides, valves or faulty valve stem seals.

    *over run = for example when you descend a hill in gear but with foot off the accelerator. The engine is acting as a kind of brake. The smoke billows out when you accelerate.

Smokey engine on start up and acceleration


Blue smoke is usually oil, white is usually coolant, and black is usually fuel.

What colour is the exhaust smoke?

When you stand behind the car with the engine running after the engine is fully warned up, do you see smoke coming from the exhaust?

Speed is lesser and smoke releases through salencer


Smoke on the exhaust shows an indication of the fault on the car engine. A blue smoke is an indication of fuel loss, a blue smoke also indicates that oil is burning due to cylinder lining or rings failure. Also blck smoke indicates high acceleration specially in diesel engines and also can be an indicator of a poor engine state.
Also if the silencer is clogged it can show up black smoke on acceleration. It will be best to check for oil use, cylinder compression and fuel use so that you can get an inference on the fault.

BLUE SMOKE FROM AUDI RS6 ON DE ACCELERATION AND START UP THINK OIL STEM SEALS ARE LETTING OIL THROUGH. CAR RUNS FINE I THINK, AND EXCESSIVE BUILD UP OF OIL IN DRIVER SIDE TURBO PIPE, 62000 MILES WITH A...


General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.
