What Different Smoke Means? Types of Car Exhaust Smoke | Explained

[@The_R-n-I_Guy]

Nothing can fix a leaking head gasket but a new head gasket. Anything you can pour into the engine is a temporary bandaid at best

[@henrykennedy1120]

K&w metallic sealer, seals it like new

[@Truthm9b]

Yeap used K& W in my son’s car, he drove it for 5 years after and still going when he got rid of it!!

[@henrykennedy1120]

Been using it for 40 years

[@billspangler2685]

True. You shouldn't put that head gasket repair crap in your cooling system. If you only drive a few hundred miles a year or you're planning on driving your beater until it breaks then scrapping it, then I guess it would be a viable option. Personally I don't like rolling the dice every time I get in the car, so I just fix it the right way 😅

[@henrykennedy1120]

K&w in the radiator seals everything forever your too young to know that

[@Mr.Benedos]

Oil leaking into the engine is especially dangerous on turbodiesel cars, because it can cause an engine runaway

[@speedydamm]

Diesel

[@wateuszkelsz]

That's one of the reasons why I prefer manuals instead of automatics, because you can save the engine, the clutch or gearbox might say bye-bye but it's still cheaper than a new engine

[@Mr.Benedos]

@@wateuszkelsz oh yeah, haven't even though of that kind of saving the engine. The best and most assured way is still to cover the turbo with a thick cloth tho

[@wateuszkelsz]

@Mr.Benedos in manual you just put it in the highest gear, release clutch then hit the brakes and hold until the engine stalls, which is way faster than getting out of the car, opening the hood and covering turbo with a thick cloth, not to mention finding that thick cloth

[@Mr.Benedos]

@@wateuszkelsz yeah pretty true now that I really think of it, that would be way faster (unless your transmission goes kaboom before the engine, in which case you would better off be hiding behind the wheel)

[@richardparker3924]

On an older car, a ruptured diaphragm in the modulator valve on an automatic transmission can cause white smoke as this allows transmission fluid to be sucked up the vacuum line and into the intake manifold.

[@DGHodgson-o8z]

I had this exact issue years ago but my car was throwing out red smoke.

you forgot to mention that white "smoke" comes out of the exhaust during colder weather

[@toyota86s]

He talked about it, he said it happens because of condensation of the water in the air. That mainly happens during the cold, and is especially more visible due to the serious temperature differential

[@mylesgreen1361]

Thats basicly what he said at the beginning. Condensation

[@claudiocosterni6488]

@@toyota86s ...well, if you hadn't asked me this question, almost provocative, it would have been better. Not for me, which obviously doesn't involve me at all and leaves me indifferent. And if in addition to this effort, while you were there, you had also added the final point it would have been even better, but that's asking too much. Haste and superficiality are an almost ineradicable disease for many, even for a Toyota lover. However, don't worry, there is much, much, much worse around the web, every day.

Here comes the climate video

[@dumymariposa6795]

8:11 -I thought that was the job of the EGR system, and the PCV valve takes some of the oil vapors to the combustion chamber in order to reduce the pressure inside the engine block.

Purple Haze Smoke on the water.

[@ate71622]

JH and Purple 👍🎸🎸✌️

[@StormsparkPegasus]

Head gasket sealer is not a permanent fix, and comes with its own issues (like clogging parts of the cooling system). Depending on how severe the leak is, it can work well enough as a "right now" temporary fix. Now, if it's not the head gasket, but something like a warped head, or cracked head or block, the engine is probably junk anyway, so might as well keep it going for as long as you can.

[@muraliparameswaran4182]

Thanks a lot for the info

this is great thanks

[@ilfarmboy]

heavy black smoke from a diesel engine is called rolling coal and is illegal to do it in most states

[@ImSyre]

Tell that to the hicks that think its cool

[@WhattaFook]

I have diesel. Once I had an old BMW with huge black smoke. Neither my technician nor the chip tuner could tell me why. A regular guy told me to hit the gas, let the engine run on high rpm, that cleans out the system. And it worked.

[@stergacha9435]

for how long did you do it ?

[@JamieWalker-pc6nd]

That’s basically a dpf delete 😂 This is the most common “mod” in the uk

[@akyraisconfused]

4:02 IT'S MILES THE HIGH MILEAGE ŠKODA OCTAVIA, WOOOOOO

[@OfficialRainsynth]

Blue smoke was also pretty common for old two-stroke cars like Trabant or Wartburg, since their engines run on a mixture of petrol and oil, which obviously produces the blue smoke. Though, these didn't use regular engine oil, these used so-called M2T oil, which is a type of oil specifically for being mixed with petrol in two-stroke engines.

[@albertastorms]

White exhaust is also normal in below freezing temperatures as there is vapour from gasoline being being burned. It is visible when the air is cold like when you see your breath in cold air. Now if you see it in warm weather then there is a problem.

[@electric8668]

Exactly

[@ryans413]

If it’s cold out the white smoke dosnt disappear it’s condensation from the hot exhaust gases and it’ll be present the entire time it’s cold outside. No different then your hot breath on a cold day. If the smoke is white and really thick that’s a blown headgasket that’s burning coolant. If the smoke is blue that’s oil being burned if the smoke is black that’s an engine that’s running rich to much fuel.

[@madmike5144]

LOL, i would never would recommend using head gasket sealant stuff that this video recommend in 3:11, when i can come later hunt you

[@girish4010]

If blue smoke is coming only after a long park, it means your valve seal is wearing up

[@ezkempinkemp3467]

My white smoke was the result of a bad valve job where the valve seats were ground into the water jacket on the head.

[@David-vj8is]

I have vintage 2 stroke small engines that take a 16 to 1 oil/gas ratio with strait non detergent sae30! Talk about blue smoke!

[@jagmarc]

How about the new types of smoke we'll all be needing know, lithium battery flame venting smoke, lithium battery thermal runaway fire smoke, lithium battery fire well under way smoke, lithium battery still burning smoke while firefighters trrying put out, and lithium still smouldering smoke while cooling down.

[@kukipeter7524]

Got a fabia mk1 that runs on lpg,it has 325k kms,no smoke,runs like when I bought it.Original wheel bearings,bushings,air con compressor,alternator

[@observingrogue7652]

Tuners, or people modifying their engines for more power, be higher compression ratios, cam timeing/lift/overlap, better airflow, nitrous, or forced induction by adding a supercharger and or turbo kit. If tuning & testing by themselves, without spending the time & money renting a dyno. They run rich on purpose, to protect the engine from detonation/knock/preignition, because the excess fuel has a cooling effect. When finding the new air fuel balance for what better hardware you changed. It's best to start a little rich, and tune the fuel rate down, to what perfect for your setup then risk being lean on a test run, and destroy the engine. Tuners, and super car computers may also run rich, if high enough octane is needed, but unavailable. Clever computers, or Tuners doing it manually, can add fuel, and delay spark timing, if knock is detected, and then reduce those things to the point there's no knock with that octane of fuel, but also not wasting it, and try to be as powerful and efficient as possible. Diesel engines can safely run lean, add a turbo no problem, even makes them more efficient, it's the opposite for them. More fuel makes them dangerously hot, but stronger, to my understanding.

[@0ptimal]

Imagine if there was an additive that you could pour in the tank and it'd make the exhaust smell good. Like pine trees or something lol

[@paskvale65]

For EV there is only a black smoke

[@TheKitchenTableGamer]

Blue smoke 95% of the time is burning oil. Low compression, leaking turbo seals, turbo oil return restricted ( which happens a lot), piston rings. Or in a diesel, the above plus timing. Obviously this list excludes anything electrical.

Too much fuel ( worn out injectors or over fuelling) or low compression. Usually the latter.
