What Does the Smoke from My Exhaust Mean?

What Does the Smoke from My Exhaust Mean?

If you see different colored exhaust fumes it’s time to pay attention to your car. Even if your vehicle isn’t flashing any warning lights, the smoke coming from your exhaust is a signal that something might not be working properly.

What does BLUE smoke from my exhaust mean?

If your car is blowing blue smoke, it’s a clear sign that the engine is burning oil. What happens is that the valve guide seals or piston rings are worn out, and oil is leaking past from where it should be lubricating the moving parts, to the combustion chamber where it’s being burned up with the fuel.

If you’re seeing this kind of smoke, check your oil regularly and watch for consumption issues. While an issue that normally should require immediate attention and expensive repairs, including some internal replacement parts, if your vehicle is old and the leak is minimal, it can be carefully managed by topping up the oil on a regular basis.

Along with environmental damage, burning oil can cause rough starts, as the process can ruin the car’s spark plugs.

There is another reason for blue smoke, and that’s if the car is turbocharged; the smoke being a sign that the blower is in need of rebuilding or replacement.

What does GRAY smoke from my exhaust mean?

Gray smoke is hard to diagnose directly. Like blue smoke, it can mean that the car is burning oil or suffering from a bad turbocharger. Take the same precautions as with blue smoke, and check for excessive oil consumption.

Gray smoke can also be an issue with your automatic transmission fluid getting burned up in the engine. A faulty transmission vacuum modulator would be the culprit in this situation, leading to transmission fluid getting sucked into the engine and getting burned up.

Furthermore, gray smoke could mean a stuck PCV valve. The PCV system (Positive Crankcase Ventilation) cuts down on harmful emissions by recycling them back into the combustion chamber. However, when the PCV valve gets stuck, pressure can build and lead to oil leaks. Fortunately, PCV valves aren’t expensive, and can be a quick job for a mechanic or a do-it-yourselfer.

What does WHITE smoke from my exhaust mean?

White smoke can be nothing to be concerned about if it’s thin, like vapor. This is probably the result of normal condensation buildup inside the exhaust system. This kind of smoke disappears quickly.

However, thicker smoke is a big problem, and can be caused the engine burning coolant. This can be the result of a serious issue like a blown head gasket, a damaged cylinder head, or a cracked engine block – all of which are costly repairs.

Don’t ignore it, however, as the problem could become far worse. Even a small leak in the coolant can lead to overheating and serious risk of damage to the engine. A coolant leak can also mix with oil and cause serious headaches for you and your car.

What does BLACK smoke from my exhaust mean?

Black exhaust smoke means the engine is burning too much fuel. The first think you should check is 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. Black smoke is usually the easiest issue to diagnose and fix, but burning unnecessary fuel will definitely affect your fuel economy, so don’t think of avoiding this one to save money, it won’t work.

Any smoke coming from your car’s exhaust pipe is a sign that your car is in distress. Pay attention to what it needs to ensure more miles for your vehicle.

    Surely the white smoke you are describing is steam, this should be easy recognised as it will quickly dissapear.
    However if we are talking diesel engines only this would indicate unburnt fuel, an inspection of the fuel injection system should be undertaken including the timing.

  • I’ve used synthetic for more than twenty years and seldom see any exhaust that concerns me. The first few minutes the most I see is steam for a few minutes but by the time I get to the first light, there’s nothing to see coming from the exhaust. A neighbor who uses synthetic 2-cycle in his scooter also has a similar experience.

  • Brian Green

    can any one tell me how to remove the rear window louvres on a mercedes 280 SLC R107 1981 model  

  • This much is true, synthetic oil may not produce any color if burned but that “colorless smoke” can also hide the fact that your valves or piston rings are damaged. 
    I have used it in 2-cycle motors back when I owned a dirt bike. The advantage was that the residue did not produce a blue cloud and was considerably more green in its use.
     But like stated about, synthetic is not a miracle oil, It cannot “heal” normal wear of those parts that will wear with use anyway.

    My car is not overheating I just bought two weeks its was driving so nice about driving for twenty mins today I felt the driving weird so I pulled over lift the hood and nothing I got home turn the car off turned it back on white smoke a thin layer started to come out what could this be the oil is very old and the radiator had brown water

  • jimi

    I have a 02 Mustang GT 4.6, when driving it drives fine, but at a stand still it idles really low. and if u just let it idle for like 5 minutes and then rev it, it will blow out smoke.

  • raza manaz

    Low/rough idle when stopped is frequently caused by a dirty throttle body. With your engine turned off and cool, remove your rubber/plastic air intake duct from your throttle body. Then use a can of throttle body cleaner and a couple rags to clean both sides of the throttle body’s moveable throttle plate to remove the carbon deposits that are a normal byproduct of combustion. DO NOT remove the throttle body from the engine because you’re only concerned with removing deposits from the edges of the moveable throttle plate and the adjacent sections of the throttle body throat. Also DO NOT use a wire brush as doing so risks removing a protective finish found on many Ford throttle bodies… if needed, just use an old toothbrush. After you reassemble everything, the engine might start roughly and you might temporarily have a check engine due to excess cleaner remaining within the intake manifold but otherwise your idle should be improved.

    I have an 89 model Mitsubishi pajero and have been using this without any problem but recently black smoke started to show, the mechanic says it is problem with the carburetor and when I showed it to the carburetor mechanic he says it Is because of the old vehicle or carburetor should be changed. I actually don’t trust the carburetor mechanic maybe he wants us to get rid of the vehicle and sell it to him. Can u please give a convincing reply ?

  • Mark

    I own a 2002 pontiac firebird v8 ls1 5.7l daily driver for me and drives great but all of the sudden I went to the store and when leaving it started really rough low idle and it sort of died out/shut of on me. Went to start it and no start, so I let it sit for a couple min and tried again and it wanted to crank so I gave a little throttle and it started but blew out a cloud of smoke, only from driver side tailpipe tho (weird) but it made me a bit nervous so I turned it off and then my dad went to start it again and it wouldn’t start now?? Is there any advice for my situation? Thanks.

  • Nik

    Ur running lean, check intake gasket and TB gasket

  • Nik

    This means too much air and not enough fuel. Check MAF sensor, try cleaning it and cleaning throttle body. Do it yourself it’s easy with some vids

  • Nik

    If it’s on one side then it’s probs the intake gasket on that side. Easy fix

  • baberham

    I have a Mitsubishi Endeavor 2004. It sat outside for the last 2 days while I had my garage sale. When I went to start it today, it wouldn’t start. When I finally got it to start, it made a horrible sound ( the type of sound your car makes when it’s already started & you turn the key to start) and then a lot of bluish white smoke came from the tail pipe. It eventually went away and drove fine ( I just drove a couple blocks to grab my garage sale signs). Any clues what might be happening? Also! On Wednesday last week I turned into a driveway to turn around. When I put my car in reverse & began to press the gas , it died but started back up quickly. I did fill it with gas that day also at a place I’ve never filled up at. Need help! I take very good care of my car. I change the oil every 3000 miles also…. HELP

    You need to replace the air intake valve. The idle is the problem. Buy the part online for discounted price. The install is approx. $30-50 or do it yourself. Watch the video on Youtube.

    I have a 2000 Vauxhall Vectra 1.6 and recently just had the exhaust changed as the old one had blown and cracked, since then the car has been smoking (white/grey) in lower gears on pull away from a stand still or when i reverse into a parking spot. The coolant level is fine and so is the engine oil, there has been no warning lights yet, a mechanic advised me it likely to be the seals that is allowing the oil to be burnt however its a costly job and dont just want to jump into this as a repair if there could be other issues. Please can someone advise? The car was fine before the exhaust got changed

    Hi all,

    We recently bought a 2008 Fiat 500 1.3 multijet diesel sport, great little motor but about three weeks later it decided to start blowing out white/ grey smoke on the odd occasion over a few weeks which then started to get more frequent to every day, so we took it to the garage for diagnosis, they couldn’t find any fault codes or any problem but advised us to get the cam chain renewed as it did have a little rattle to it, we had the work done for £480. Not bad we thought for piece of mind. Next day the car was blowing out white/grey smoke again, nothing to do with the timing then but at least she now sounds sweet, we had no water loss or oil loss , no power reduction, no rough tickover, or any bad symptoms at all, just white/grey smoke out of the very smelly exhaust.
    So I got to searching the interweb only to find an article about diesel fuel and how susceptible it is to contaminants (water etc) which can lower the pressure in a common rail diesel engine which can cause all sorts of problems including white/grey or even black smoke. That’s it! I thought to myself, so I drained the fuel tank via the engine filter feed pipe only to find a gallon or two of murky/cloudy diesel fuel in my clear container! So I re-fueled with a litre of clean diesel and drained again several times until clear fuel reached the engine filter, cleaned the filter then re-fueled with fresh diesel. So far no more smoke signals from the 500! So there you go, smoke out of your exhaust may just be bad fuel, it’s worth checking before you have a big garage bill, but at least we have piece of mind that our cam chain is new at 69000 miles.

    I had the oil changed in my 2006 Honda Civic Dec 19, 2015 and flew out the next day on vacation. The car sat the whole time until my return Dec 31st. When driving from the airport, there was a very loud buring smell about 25 minutes into the drive. I stopped to get food and it took about 15 min to restart. The next day, the car started with no problem, in roughly 15 minutes it began to smell with very little acceleration, couldn’t go over 10 miles. All the check engine lights came on and a huge cloud of black smoke started coming from the engine. I thought the car was on fire. Because this happened over the weekend I have to wait until Monday to find out what happened.

    Hello, I could not really tell if the smoke from mine is white or gray smoke, it only happens while accelerating on the interstate and I push it’s RPMs.

    I have slight transmission issues, too costly to fix right now, my main concern could be would this exhaust be from my transmission or is it another separate expensive fix like blown gaskets, cracked cylinder, or engine block?

    Please help me chose the best route, I just bought the damn thing, was working fine until a month after I got it.

  • Miss Hooi

    I have bought a new Mercedez C200d diesel engine since Mach 2016. Its has start emitting white thick smelly smoke from the exhaust after the 3 weeks while driving it. Complaints to Mercedez dealer and they could not find anything wrong with it and told me its normal as it is steam and due to Diesel filter trying to burn out wax from new parts and they told me to monitors it. Its still giving me the same problem emitting white thick smelly smoke and this is the 6 times reoccurrences since I bought this new car. Please advice as I could not see any leak from the car bonnet, to avoid the warranty, could I send my car to other garage to check for second opinion as Mercedez kept saying it is very normal.
    I am afraid this new car might cause me a great bill of repairs and maintenance at later stage.
    Please can someone tell me what is my status, as I guess Mercedez will not exchange another new car for me.

  • John Higgins

    You should have placed a comma after “I”, and “myself”, to help the sentence flow better. Since don’t is a contraction, you need to add the accent after the letter “n”. In addition, you also spelled “writting” wrong twice (it has one “t”…not two). You also need to place a contraction in “Im” and “cant”. Furthermore, you should not have capitalized the “J” in just, because it neither comes after a colon, nor does it begin a new sentence. Don’t forget to capitalize the letter “i”, when it stands alone. With a little practice, you, too, could become literate in English. :0)

    I have a 95 Eddie Bauer Ford Explorer I ended up overheating it because a coolant hose busted and I tried getting the rest the way to the part store fixed the hose there but damage was already done I’m not sure what it exactly is but there’s white steam/smoke out the exost and one thing I am sure of is that it’s burning antifreeze. I already used a $40 bottle of Blue Devil in the radiator and I think it made a pretty good difference but it definitely didn’t fix the problem completely. All I can think of is to throw one more bottle of blue devil in it and hope it seals everything that it missed the first time… anyone have any suggestions? Please and thank you any info would be appreciated.

  • jeanette fisher-scruton

    Have a 95 camaro 3.4, recently had a Bucky ride and took it in to a shop…when they tried to move it it was dead…so they put it into the garage it did not turn over….nothing….so they came to the conclusion it was the fuel pump and replaced it for over a $1000…when I drove off it was smoking white smoke which is never did before…what is going on??? Also could the emission control device have anything to do with it? …and at my last oil change they brought to my attention that the head gasket was leaking…and lastly after getting it going again (still strong smelling, eye watering white smoke, smoking on the starts and idle) .
    It ran beautifully for awhile and then one night i parked it in the garage and in the morning i turned the key without a sound coming out of it…on random days I tried to start and it randomly started and ran smooth with smoke on the start ups…wiring was noted to need repair…What the!!!!!!

  • bootkiller09

    i got a ford e250 2004 cargo van. i have no external oil leaks that i see or that is showing up on my driveway.. not sure why my van is blowing out white or maybe blue i guess smoke out tailpipe.. this only happens when started. once it runs for 30 seconds to a min its gone. how ever i noticed it.. changed my oil 2 weeks ago. went to check it today and level didnt even show up on the dip stick. i got a check engine light but its for idle air control valve that is the high idle i experience when all this happend. van has 180k on it and use synthetic high milage oil and extended filter and change my self. cost me 50 to 60 each time this way.
    how ever.. im just wondering a few things.. does it mean a blow head gasket? does it mean a cracked block? what could this mean? with no exterinal oil loss besides the tailpipe is black and oily. what can i do to fix it my self ? or can i not? what are ways i can try to pin point what the exact problem is.. i really dont want to put more money out i just put a new trans in my escalade and costed me a fortune and that was due to someone borrowing my car and driving at high speed and hit a speed hump and he claims it wasnt him. but hte person with him says he did.. either way.. im just trying to see if i should repair the motor or just get a new van or fix the issue.. help please thanks

  • East Rool


  • Dan Apthorp

    This tells me there is something wrong happening. I would ask a good mechanic and see what he would say as a blown head gasket and cracked block does the same thing. Your mechanic should not charge for advice . This could have been caused by driving the car at a high speed. Sounds like it could wrecked.

  • Furthermore, gray smoke could mean a stuck PCV valve. The PCV system (Positive Crankcase Ventilation) cuts down on harmful emissions by recycling them back into the combustion chamber. However, when the PCV valve gets stuck, pressure can build and lead to oil leaks. Fortunately, PCV valves aren’t expensive, and can be a quick job for a mechanic or a do-it-yourselfer.
