Why does black smoke pour out of my exhaust when i accelerate in my Rover 25?
Answers:
Does no one here know anything about exhaust smoke? Geez..
Black smoke = rich fuel mixture. Sounds like too much gas and not enough air. Check your carb.
Blue smoke = oil burning. Could be caused by valve seals, worn pistion rings, etc. Internal engine issues.
White smoke = burning coolant. Blown head gasket most common cause.
Its burning oil.
what he said, or you need a new exaust system.
Burning oil, either the head gasket or piston rings are shot.
Rings are probably worn..Sorry
Because it is burning oil.
Replace your air and oil filters and check your oil . It may be time for a change
is it diesel?
Oil Burning matey!
Needs Sorting!
Not all of the gas is being completely burned away. If it were burning oil you would get white smoke. With old carburetors it would indicate that the mixture wasn't right. I don't know what you would do for fuel injection to fix it.
change oil and filter.
burning oil
Because its a Earth destroyer. It was designed to pollute the air and DESTROY the Earth.
Because it's a Rover !!
.seriously, check your spark plugs and give them a good clean, if it still happens, get the engine checked out.
Please drive your truck up real close to your monitor so I can take a closer look.
to much oil in the engine
oil seals gone.
YOU OWN A WHAT? god how do you have the guts to come on here and say you own a rover 25..i wouldn't worry about the black smoke..i would worry about finding a shrink.lol
some bastard might have put old oil in your tail pipe.
What CC engine is it? If it's the 1.8 engine they are renowned for blowing the head gasket. Ask any rover dealer, they have now included the head gasket change as a major service item.
Its also on the MGTF and the Freelander (same engine)
black smoke isn't oil burning - that makes grey/blue smoke.
is your car diesel?
your fuel/air mixture is prob. wrong.
If you have a diesel engine. it is supposed to pour black smoke. If you have a petrol engine, it's burning oil. But then, it's a Rover. isn't it?
coz it's shagged
I tend to agree with the other answers but also it maybe wants a new air filter ,( a blocked air filter = mixture far to rich = black smoke ) by the way, is it diesel or petrol? if it was a diesel any of the above or knackered injectors.
since there is more fuel sent into the Engine to accelerate , The Engine is not able to burn all the amount of oil so You get black smoke.
Blue smoke is oil. Black means gas. White or a steam like smoke means water. Try running some fuel cleaner thru your tank.
Sigh.
BLUE smoke means your car is burning oil, which is unclean and doesn't burn completely.
White smoke is burning coolant (so you get whitish steam).
Black smoke is soot, which is basically because you're running very rich.
Another reason it's most likely running rich versus having shot internals is the fact that you only get smoke when you floor it, whereas leaking oil would most likely net you smoke regardless of throttle position.
If you have an EFI (electronic fuel injection) car, run some fuel system cleaner through it and see if that helps at all. If not, you might have an injector that's stuck on open, I would suggest taking it to a shop.
If you have a carbuereted car. also shop, unless you feel like re-jetting your own carb.
Ofcourse, this also depends on you diagnosing the color of your smoke correctly. A simple check would be to see how your mileage is doing, and your car's performance, along with the oil level.
If it feels more sluggish and gets worse mileage, but the oil looks fine and relatively clean, it's probably the injectors. But if your mileage is relatively okay but your oil level drops without any noticeable leaks, it might be that you're seeing blue smoke.
Cylinder head gasket blown??
black smoke is a to rich on fuel problem -blue smoke is oil and white steam is water . if its black you have a fuel problem
Sound to me like the rings have gone mate. ( Check the plugs..if there covered in black soot then its knacked )
I agree with everyone who said rich fuel mix condition. BLACK smoke from a vehicle indicates rich fuel mixture and your engine is not burning all the fuel going into it. BLUE color smoke is oil. And WHITE smoke is coolant. The fuel regulator may be bad causing too much fuel to be injected into the cylinders. Have the vehicle checked with a scanner and it will tell you exactly what is causing your rich air/fuel mixture.
