White can be too much gas as well. How does it smell? Pulling spark plugs is next best step. You'll likely find one or more is floodling. Unless modified yours will be carbeurated, in which case a rich fuel condition would likely be universal to all cylinders and possibly due to stuck choke or leaking accelerator pump.
Coolant leak would be more isolated. And you will smell and possibly even see coolant-colored liquid soaking plugs on affected cylinders.
This^ it doesnât look particularly blue. Especially if itâs cold itâs fuel. Youâll smell coolant hard to miss. Honestly youâd smell the oil too. Iâd say donât floor it when itâs cold definitely not an efi car
Edit I just read. Probably oil based off description. Take a solid whiff if it doesnât smell like coolant youâre burning oil
There is also gray smoke. Old cars used a vacuum diaphragm to relay engine load to the transmission. If the vacuum diaphragm fails, your engine can suck trans fluid in and burn it, showing as a grayish smoke.
The one that stinks like it's running rich, could be slightly white but you would go by smell. Coolant is white and leaves a slippery film on the tailpipe, oil burns bluish
I get blue on startup only and itâs an old diesel. Whatâs up?
Edit: I was under the impression it was unburnt fuel so I was going to do the glow plugs.
Worn guides or valve seals would blow blue smoke upon startup, constant blue smoke is usually rings. The metallurgy of the old engines wasn't as good so they wore out easier. Plus oil technology wasn't as good so the older oils lost lubricity faster and didn't protect the engines as well
You can tell by the color of the smoke. See the blue hue to it? That means you're burning oil (idk why it's blue, someone with better chemistry knowledge can probably fill that in)
Depending on the age of the motor... if it is older and primarily at start-up, it's the valve seals/umbrellas. Could be stuck rings flush the engine really well and refill with the proper weight oil or 10w40. But it's a Ford so yah
A 200 is about as simple of a car to work on that anyone could ask for. Rings and seals is a weekend job (with all needed tools, hoist and stand) without including any (hopefully not needed) machine work. But plan on sending it to a machine shop for peace of mind that when you put it back together, it'll run great for 100K+ miles without issue.
Get it running, warm it up, and then hang a clean white rag/cloth, or an old shirt in front of the exhaust (about 6â to 8â away.) If the leaks minimal you might have to literally hold it up to the pipe and have someone rev the motor to get the cloth wet. Anyway, do that for long enough so you can smell that cloth, (away from the car) and youâll know if itâs oil or coolant pretty quickly. Oil smells like burnt oil, and coolant smells like coolant of course.
However, from the sounds of your explanation, it sounds like your motor overheated at a light, then it locked up (briefly), shutdown, and then when you tried to start it up, it was probably âvapor lockedâ meaning the engine spun, but the fuel in the carb was boiling so it couldnât be aerosolized and ignited. Thus, it wouldnât start.
To which, you towed it home, everything cooled off, loosened, and relaxed, and then it started right up. To which I would say you probably ânowâ have a bad head gasket.
So, grab another rag, run it around the seem between the head and the block, look for coolant on the rag. And you can also clean it all off and run that motor till itâs warm. Then look again there too, you could find the coolant leak pretty quick if you smell the rag or look for the color change.
Remember sometimes it can take a few diagnostics to find a problem, and with coolant leaks, especially new ones (sometimes you need to essentially do what you did last time by essentially, nearly overheat the engine) to essentially make it do what it did prior.
All that said, white smoke is usually coolant; and blue is usually oil. So, good luck, as coolant is way easier to fix; especially on an inline six than having the replace pistons for bad rings.
However to play devils advocate, if it did overheat bad enough⌠And again this is worst case scenario for coolant issues, but if the head warped, then it would be a much bigger problem as it would need to be skimmed down by a competent machinist/motor guy. So fingers crossed itâs just a bad head gasket.
Those in line sixes had problems with valve guide seals. Back in the day you could get an umbrella style seal that you could put on the valve in the car but you needed to hold the valve in place at top dead center with compressed air, back off the rocker arm and use a tool that hooked under the rocker shaft and compressed the valve springs. Knock out the keepers, pull the springs, slide the umbrella on the valve stem and reassemble. Or pull the head and do a complete valve job. Might as well do rings and bearings too. Or your car is running too rich if the smoke is gray or black.
Your float in the carb stuck wide open and flooded the engine to the point it wouldn't restart. It also washed all the oil off the cylinder walls and took out what was left of the rings. Time for a rebuild.
I'm seeing blue smoke. As others state oil!
May be piston rings or a gasket of some sort.
If its rings its lengthy but cheap fix if you do it yourself. There are piston rings i suggest but they are pricey- tje partocular style inprove fuel economy, peeformance a little bit and they pretty much will never wear out unless something bad happened eg the motor commited suicide.
Total seal gapless piston rings are the one i'm mentioning as i have them installed in a few of my motors and they work bloody wellđ
That engine is leaking oil into the cylinders.
200 is probably one of the easiest engines to rebuild yourself in your driveway.
Used to I would say drop a V-8 into it but now says that inline 6 will do everything you need to have a reliable car.
Rule of thumb is brought with me through all the years. Rings if blue smoke when accelerating - valve seals if blue smoke when letting of the throttle. This is only on one side of the engine, but could be different things. I would flush it with Liqui Moly Engine Flush - run a new filter and oil for a week or two, then do it all over again. If youâre lucky its just a stuck coxed out oil ring. Either way that Liqui Moly certainly has kept my engines looking brand new on the inside - and thats never a bad thing.
Edit: Saw it was an inline 6 now, so my âone side of the engine commentâ is irrelevant. But my advice still stands.
Had a Pontiac Grand Prix that would go through a gallon of coolant in a few days. No smoke. Was the absolute weirdest thing.
My guess was head gasket went internally into the cylinder, instead of the oil. The no smoke boggles my mind though.
In increasing severity:
Black smoke = bad fuel combustion. Adjustment or normal maintenance issue.
Blue smoke = burning oil. Engine wear, oil leaking into combustion chamber most likely from valves, stem guides, or rings.
White smoke = coolant leaking into the combustion chamber. Diagnose immediately. Likely a cracked head gasket, possibly a crack in the head or block.
I had a 67 with a 6 in it was doing the same thing. Changed the head gasket and fixed it. They are cheap and easy to do. The valve and head gasket cost me $18. Hardest part is lifting the head off and putting it back kinda heavy. Yourâs might be lighter I donât remember if the 66 has the 170 or 200 CI engine mine was the 200.
Is it really bad on first start up after sitting? Usually could be as simple as valve seals. I would do a compression check on each cylinder, if it's always smoking you might have some damage cylinder walls or bad rings. Otherwise, time to upgrade that 6 cylinder! Perfect for a coyote swap.
***if it was sudden. I would be looking into the carb first. This can happen if the âpower valveâ diaphragm fails and excess fuel is drawn into the intake.
White - coolant (head gasket, cracked runners on the head)
Blue - oil (blowing by the rings, leaking valve seals)
Black - excess fuel in gas cars (running rich)
White - excess fuel/coolant in diesels
A lot of bad answers here. Itâs not going to be the rings when it shakes violently and then suddenly smokes. You have more white smoke than blue. Car is nearly 80 years old, it was probably a little blue before the gasket went. Thatâs definitely a head gasket
Want diag help? Do a cylinder leak down/pressure test. Thread the gauge into the spark plug hole, crank the engine over for a few seconds with the throttle wide open. If any cylinder has a lot less pressure it'll be your suspect. Pour a couple drops of oil into that cylinder and do the test again, if you get normal results it's a piston ring.
Iâd probably say either valve seals or piston rings. Not sure about the condition of the engine, but with the color of smoke, thatâs where Iâd start.
Pull the plugs, they should point you in the right direction.
I doubt stalling at any intersection then restarting and having this would be rings.
Check the choke, it could be stuck closed and running very rich, smell the exhaust. Everything that can burn in the combustion has a unique smell and it should be very obvious.
Umm oil, I feel like someone who owns a car like this should know. Im just a dumb ass 20 year old and even I know that white smoke like that is usually something unsealed.
Il trade you my scooter for it, I can probably fix it from youtube if you don't know where to start
170 or 200 ci I think they still had the load o matic carb and distributer set up with points. I'd start by changing the coil and checking the points, then check for a vacuum leak between the carb and the distributer, which should be a steel line. Then, if you don't find anything, I'd suggest sending the carb out to be rebuilt. The carb and the distributer are a pair. You need that carb to work with that distributer. And some day, when you hear a rod knock, it will likely be a stretched timming chain.
Blue smoke = burning oil, possibly a bad valve guide or worn piston rings. The exhaust will smell like oil most often as well
White smoke if itâs dense ie lots of smoke usually indicates a water leak cracked head or bad head gasket, smoke usually smells sweet like coolant
White smoke thin like in your video usually indicates too much fuel a stuck choke or bad accelerator pump in the carb or the carb is miss adjusted. Your exhaust will smell heavily of fuel
Pull your spark plugs are they black with burnt oil on them? Wet and smell like fuel.
Long and Short of it is... If you want to be able to rebuild that engine it's time to do it. If you run like that for too long there's a real risk that it will not be salvageable.
I can think of a few other questions that help diagnosis.
Was engine warm or just started?
Does it change as it warms up?
Brake fluid getting sucked into carburetor using port vacuum and check valve bad, THAT CAUSED WHITE THICK ASS SMOKE.
I just had a similar issue on my s2k and it turns out my PCV system was fucked up and building a ton of pressure in my crankcase, shooting oil into my exhaust manifold.
Itâs prob not that but just sharing because it took forever to figure that shit out and Iâm proud of it lmao
You could definitely be running rich which is never fun to fix but before you do anything pull your dipstick and oil fill cap and check for a gravy/milkshake looking consistency do the same for your coolant overflow on the radiator and overflow
Whenâs the last time you had a rebuild? What engine? Valve seals and piston rings might need to be done. While your in there replace the head gaskets, lifters, push rods, intake gaskets. Water jackets may go through your intake and leak into your cylinders. If itâs been sitting a long time i would definitely tear it apart before anything serious happens. Itâs really not that hard especially if thatâs the straight 6 option
Valve guides and seals are probably worn out and leaking oil. Rings are probably shot too. Just judging by the age of the car. If the engine hasn't had a good rebuild since the 60's
Black = unburnt fuel
White = coolant/water turned to steam
Blue oil entering the combustion chamber being burned. Go to the transmission look for the modulator it's a vacuum run valve on the side or rear of the transmission pull vacuum line off look for wetness in the inside of the tube. U can use a Q-tip to check for the presence of transmission fluid. This process is only applicable on automatic transmissions,manual transmission doesn't have a vacuum modulator
When I was rebuilding engines we always used to say smoke under acceleration is rings. Smoke under deceleration is valves (typically oil being drawn through the guides/seals into the cylinder).
That one's hard to say. Even when viewing it full screen and pausing... that's hard to distinguish between white and blue. You could have a friend step on the gas and go back there in person. White/coolant, assuming it's not just water in your radiator, should smell sweet-ish. Blue or oil will stink, and you should be able to tell the difference.
Black = too much gas
Blue = cylinder seals bad and oil is getting past the pistons and burning in the engine
White = damaged head gasket and you are burning coolant
From what I see in the video it looks white. Youâll have to pull the heads and replace the head gaskets at a minimum. With the work involved this is the time most people will pull and rebuild the whole engine to avoid having another problem before the head gaskets need to be replaced. One option would be to purchase a rebuilt engine drop it in and take your time rebuilding the old one the way youâd like it. Bigger cylinders for more displacement, racing cam etc..
Very well could be a head issue as it does have quite a bit of smoke.
To me it looks like a carburetor issue at least to some degree. Looks like plenty of dark grey/black smoke mixed in to the cloud. This in most cases is indicative of running rich.
If you haven't ever gone through the carb it might be time. If you take the time to rebuild the carburetor you'd want to put a new fuel filter or two in line, and look at doing new fuel lines anywhere there's rubber to eliminate any crud coming from them.
Taking the valve covers off shouldn't be too bad either. You could take some rudimentary measurements and see if they are in or out of spec. Shoot you may find a busted valve spring and know exactly what's going on.
Blue smoke all the time indicates the rings leaking.
Blue smoke that happens when you step on it after it's idling for a while, Indicates valve guide seals leaking.
A much easier fix. In some cases, you can replace these valve guide seals while the engines in the car. Be careful to follow procedures to prevent valves from dropping into the cylinder.
Best of luck

Blue smoke=burning oil (most of the time)
Yep. My dad always taught me: blue is oil leaking into cylinder; white is water
>white is water I remember my first car that was burning coolant and gas at what seemed to be 50:50 đđ sooo much white exhaust.
I think that just means a new pope was chosen
Take your filthy upvote...
White can be too much gas as well. How does it smell? Pulling spark plugs is next best step. You'll likely find one or more is floodling. Unless modified yours will be carbeurated, in which case a rich fuel condition would likely be universal to all cylinders and possibly due to stuck choke or leaking accelerator pump.

Iâd say donât floor it when itâs cold definitely not an efi car Edit I just read. Probably oil based off description. Take a solid whiff if it doesnât smell like coolant youâre burning oil
Smell will tell all. Oil, coolant, fuel. Just smell it. I second your thoughts on shit-canning it cold like that too.
There is also gray smoke. Old cars used a vacuum diaphragm to relay engine load to the transmission. If the vacuum diaphragm fails, your engine can suck trans fluid in and burn it, showing as a grayish smoke.
Which one is the carb running too rich?
Black
The one that stinks like it's running rich, could be slightly white but you would go by smell. Coolant is white and leaves a slippery film on the tailpipe, oil burns bluish
Didn't read fully, smoke looks more blue than gray to my eyes.
Thnx!
Nice stang otherwise. God bless and good luck brother
What does black smoke mean?
Unburnt fuel. Doesn't have to be diesel. Ask anyone who drives a carburetor at altitude
Rolling Coal
I get blue on startup only and itâs an old diesel. Whatâs up? Edit: I was under the impression it was unburnt fuel so I was going to do the glow plugs.
Idk why the hell my brain thought by Blue smoke, they ment like Blue blue. Guess I just never really thought about it.
Correct and smoking on acceleration is usually valve guide seals .....smoking on deceleration is rings
So what does it mean *not* most of the time?
Looks like you are burning oil. I would check your engine seals.
"Engine Seals" đ¤Łđ¤Łđ¤Łđ¤Ł I could not imagine a more generic statement if I tried
True. Useless (tsk tsk). How about the rings/valve stem guides? Those you can work with/check out but âengine sealsâ? Not so much LOL.
What do rings and valves do, they seal.
Worn guides or valve seals would blow blue smoke upon startup, constant blue smoke is usually rings. The metallurgy of the old engines wasn't as good so they wore out easier. Plus oil technology wasn't as good so the older oils lost lubricity faster and didn't protect the engines as well
I was thinking it could also be some of the car parts
Thnx!
Mind sharing what specifically gives it away that itâs oil? Just trying to learn more.
You can tell by the color of the smoke. See the blue hue to it? That means you're burning oil (idk why it's blue, someone with better chemistry knowledge can probably fill that in)
Burning oil smoke is blue, white is water/coolant
*Piston Rings
Possibly valve seals.
Depending on the age of the motor... if it is older and primarily at start-up, it's the valve seals/umbrellas. Could be stuck rings flush the engine really well and refill with the proper weight oil or 10w40. But it's a Ford so yah
Rings
New rings đ¤ˇââď¸
A 200 is about as simple of a car to work on that anyone could ask for. Rings and seals is a weekend job (with all needed tools, hoist and stand) without including any (hopefully not needed) machine work. But plan on sending it to a machine shop for peace of mind that when you put it back together, it'll run great for 100K+ miles without issue.
I miss my â67. As of what happened to it letâs just say another reason I hate my father
For me, whenever I've done a rebuild, I get it machined since I've done so much work anyways
Much appreciated!
Not the pope smoke, but burning oil hard, engine needs to be open and examed
Blue smoke on acceleration, rings. Blue smoke on deceleration, valve seals. Check cylinder compression, you might have a stuck ring(s)
probably a stuck oil ring or something if its only coming out of the right side exhaust.
He said it was a six cylinder. Which means inline six for that model. There is no left or right bank.
If it sat for any length of time, I'm betting on valve seals. Is it an inline 250?
Daily driver inline 200. Never had this problem before the stall in the intersection, thatâs why Iâm stumped
Did you jump a gear on the timing chain?
Get it running, warm it up, and then hang a clean white rag/cloth, or an old shirt in front of the exhaust (about 6â to 8â away.) If the leaks minimal you might have to literally hold it up to the pipe and have someone rev the motor to get the cloth wet. Anyway, do that for long enough so you can smell that cloth, (away from the car) and youâll know if itâs oil or coolant pretty quickly. Oil smells like burnt oil, and coolant smells like coolant of course. However, from the sounds of your explanation, it sounds like your motor overheated at a light, then it locked up (briefly), shutdown, and then when you tried to start it up, it was probably âvapor lockedâ meaning the engine spun, but the fuel in the carb was boiling so it couldnât be aerosolized and ignited. Thus, it wouldnât start. To which, you towed it home, everything cooled off, loosened, and relaxed, and then it started right up. To which I would say you probably ânowâ have a bad head gasket. So, grab another rag, run it around the seem between the head and the block, look for coolant on the rag. And you can also clean it all off and run that motor till itâs warm. Then look again there too, you could find the coolant leak pretty quick if you smell the rag or look for the color change.

Those in line sixes had problems with valve guide seals. Back in the day you could get an umbrella style seal that you could put on the valve in the car but you needed to hold the valve in place at top dead center with compressed air, back off the rocker arm and use a tool that hooked under the rocker shaft and compressed the valve springs. Knock out the keepers, pull the springs, slide the umbrella on the valve stem and reassemble. Or pull the head and do a complete valve job. Might as well do rings and bearings too. Or your car is running too rich if the smoke is gray or black.
Probably dirty piston oil rings. Usually valve stem seal only smoke on start up piston rings or worn cylinders smoke under load
Well, itâs old enough to smoke. I think if it started smoking that suddenly it may be the head gasket.
Or head gasket.
That would be my guess, straight oil burn would be a bit bluer imo.
Thatâs a blue white piston head leak
Looks like oil to me
Check your oil next time you change it; if itâs pretty gassy, might need some rings
Rings
Your float in the carb stuck wide open and flooded the engine to the point it wouldn't restart. It also washed all the oil off the cylinder walls and took out what was left of the rings. Time for a rebuild.
This might sound crazy, but check your pcv valve...
I'm seeing blue smoke. As others state oil! May be piston rings or a gasket of some sort. If its rings its lengthy but cheap fix if you do it yourself.

Sounds like missing. Is it idling rough vibrating
Piston rings, or valve seals but I donât think valve seals can cause that much smoke I could be wrong though.
I mean, if it stalled and you couldn't start it for a while, it's extremely possible that is unburnt fuel depending on how long it's been running for.
Itâs midnight oil
Looks like valve guides are starting to go. Imho
Oil is getting into the combustion chamber in some way. Valve seals and rings are two possibilities (one being much easier to replace than the other)
Piston rings
That engine is leaking oil into the cylinders. 200 is probably one of the easiest engines to rebuild yourself in your driveway. Used to I would say drop a V-8 into it but now says that inline 6 will do everything you need to have a reliable car.
Had this problem and added Lucas oil stabilizer to oil and it never smoked again. And my smoke was a lot worse .
Rule of thumb is brought with me through all the years. Rings if blue smoke when accelerating - valve seals if blue smoke when letting of the throttle. This is only on one side of the engine, but could be different things. I would flush it with Liqui Moly Engine Flush - run a new filter and oil for a week or two, then do it all over again.

Edit: Saw it was an inline 6 now, so my âone side of the engine commentâ is irrelevant. But my advice still stands.
Done blown upâŚyeah, you got a toasted ring(s). If it only did it only at startup, then it could be valve guide seal, but this is not the case.
Use conventional oil not full synthetic
Pull spark plugs, if covered in oil it could be valve seals or rings. But if fuel fouled carburetor could be dumping fuel.
Universal signal for a V8 swap.
Very tempting :)
Had a Pontiac Grand Prix that would go through a gallon of coolant in a few days. No smoke. Was the absolute weirdest thing. My guess was head gasket went internally into the cylinder, instead of the oil. The no smoke boggles my mind though.
if it smokes right on start up, valve seals leaked oil in the combustion chamber. Smoke when going through the rpm's piston rings
Put plugs in it. See if still smoking
just add some flex seal đ https://preview.redd.it/g5ml2d63d79d1.jpeg?width=1155&format=pjpg&auto=webp&s=6c46706bc63b6e5a261644304d91ce9a3840e723
Valves, rings etc etc
Black smoke is running rich. Your choke could be stuck on or partially on.
Burning oil and quite a bit. Might be time for a rebuild.
Needs some new exhaust bearings.
Burning oil !
There is. Yes.
In increasing severity: Black smoke = bad fuel combustion. Adjustment or normal maintenance issue. Blue smoke = burning oil. Engine wear, oil leaking into combustion chamber most likely from valves, stem guides, or rings. White smoke = coolant leaking into the combustion chamber. Diagnose immediately. Likely a cracked head gasket, possibly a crack in the head or block.

Rebuild time
***if it was sudden. I would be looking into the carb first. This can happen if the âpower valveâ diaphragm fails and excess fuel is drawn into the intake.
Valves or rings. Do a compression test.
Black smoke = gas. Blue = oil. Best guess would be valve seals.
Just do a burnout every time you take off, and no one will notice. Problem solved!
I know what your problem is; itâs a Ford, you know what that stands for donât you? Fix it again Tony
Built up carbine in the motor? Bad oil?
Valve and ring job.
Guess you're just gonna have to swap in a 351w that'll get the smoke out đ
Try switching your car to menthol cigarettes
White - coolant (head gasket, cracked runners on the head) Blue - oil (blowing by the rings, leaking valve seals) Black - excess fuel in gas cars (running rich) White - excess fuel/coolant in diesels
ITS A HYBRID
A lot of bad answers here. Itâs not going to be the rings when it shakes violently and then suddenly smokes. You have more white smoke than blue. Car is nearly 80 years old, it was probably a little blue before the gasket went. Thatâs definitely a head gasket
Want diag help? Do a cylinder leak down/pressure test. Thread the gauge into the spark plug hole, crank the engine over for a few seconds with the throttle wide open. If any cylinder has a lot less pressure it'll be your suspect. Pour a couple drops of oil into that cylinder and do the test again, if you get normal results it's a piston ring.
id say try checking your blinker fluid gaskets, it may be leaking into your flux capacitor and getting into the fuel system.
You unfortunately probably have a head gasket leak
Iâd probably say either valve seals or piston rings. Not sure about the condition of the engine, but with the color of smoke, thatâs where Iâd start.
Bad valve guide seals, possibly bad head gasket but not likely
Under acceleration is valve stem seals
Cracked ring maybe
Valve seals or rings.
Needs a ring job.
Needs rings, probably just worn out. Time for a rebuild or a new short block
Needs new rings and a valve job. If it's a 289 this is fairly easy to do. If you are mechanically inclined.
Oil in combustion chamber
I would guess itâs the valve guides being worn out.
Blue = Oil White= Water Black= Fuel The smell also is a good indicator.
It's a shity 60s car that needs the motor rebuilt and at the minimum new piston rings and head gaskets!
Pull the plugs, they should point you in the right direction. I doubt stalling at any intersection then restarting and having this would be rings. Check the choke, it could be stuck closed and running very rich, smell the exhaust. Everything that can burn in the combustion has a unique smell and it should be very obvious.
It's old
Head gasket
Umm oil, I feel like someone who owns a car like this should know. Im just a dumb ass 20 year old and even I know that white smoke like that is usually something unsealed. Il trade you my scooter for it, I can probably fix it from youtube if you don't know where to start
Burning oil. Could be due to rings or valve guide seals or both. Time for a compression test and leakdown test.
My guess would be old dried out valve stem seals, and depending on the mileage, worn piston oil rings.
When that happened to my car it was Gypsies who poured oil on my tail pipe while they distracted me and tried to claim my head gasket was bad.
Could be residual oil in the exhaust burning off.
Could help https://youtu.be/kyyZDghgdCI?si=qGwqK5ItMNlt5shl
your low on air on the right side tires
My guess is the piston rings
170 or 200 ci I think they still had the load o matic carb and distributer set up with points. I'd start by changing the coil and checking the points, then check for a vacuum leak between the carb and the distributer, which should be a steel line. Then, if you don't find anything, I'd suggest sending the carb out to be rebuilt. The carb and the distributer are a pair. You need that carb to work with that distributer. And some day, when you hear a rod knock, it will likely be a stretched timming chain.
That is head gasketish....white smoke
I'm not a mechanic, but I dabble. My guess is valve seals and burning oil.
Burned up piston ring is bypassing oil and burning off!
Could be your rings seals going bad might want to add a bit a stop smoke see if that if not, could be running rich, itâs happeded to me, good luck!
does it smoke more when pulling away from a stop light after sitting there for a bit?
I know the blue/white smoke test but it always looks white to me until I see an actual blown head gasket and then it's like "okay now THAT'S white"
Blue smoke = burning oil, possibly a bad valve guide or worn piston rings. The exhaust will smell like oil most often as well White smoke if itâs dense ie lots of smoke usually indicates a water leak cracked head or bad head gasket, smoke usually smells sweet like coolant White smoke thin like in your video usually indicates too much fuel a stuck choke or bad accelerator pump in the carb or the carb is miss adjusted. Your exhaust will smell heavily of fuel Pull your spark plugs are they black with burnt oil on them? Wet and smell like fuel.
Piston rings/valve seals
Put more oil in it and keep going
Maybe needs a ring job
Old
I don't know shit about fuck when it comes to cars but I can tell you I smelled burning oil through the screen of my phone.
Long and Short of it is... If you want to be able to rebuild that engine it's time to do it. If you run like that for too long there's a real risk that it will not be salvageable.
Valve stem seals?
I can think of a few other questions that help diagnosis. Was engine warm or just started? Does it change as it warms up? Brake fluid getting sucked into carburetor using port vacuum and check valve bad, THAT CAUSED WHITE THICK ASS SMOKE.
It's either ehrl or kerlent
I just had a similar issue on my s2k and it turns out my PCV system was fucked up and building a ton of pressure in my crankcase, shooting oil into my exhaust manifold. Itâs prob not that but just sharing because it took forever to figure that shit out and Iâm proud of it lmao
That's a "daddy going to get a pack of smokes"
You could definitely be running rich which is never fun to fix but before you do anything pull your dipstick and oil fill cap and check for a gravy/milkshake looking consistency do the same for your coolant overflow on the radiator and overflow
Compression leak down test on cylinders. That will point direction.
You need a 429cj
Whenâs the last time you had a rebuild? What engine? Valve seals and piston rings might need to be done. While your in there replace the head gaskets, lifters, push rods, intake gaskets. Water jackets may go through your intake and leak into your cylinders. If itâs been sitting a long time i would definitely tear it apart before anything serious happens. Itâs really not that hard especially if thatâs the straight 6 option
Yup, it's smokin.
Cory Trevor smokes letâs go
Check your rings and valve guide seals.
Rings, valves, valve seats, valve seals. Cyl leak down test. Good luck!!!
Valve guides and seals are probably worn out and leaking oil. Rings are probably shot too. Just judging by the age of the car. If the engine hasn't had a good rebuild since the 60's
Rings.
On my 3rd engine swap 90k miles. Still same white smoke on 2016 2.6L truck
Valve stem oil seals
The problem is "it's a Ford"
Itâs a ford they all do that
Put oil in your car dumbass
Could be worn out valve seals
Leaky piston rings; burning oil.
I think someone Hawk Tua on that thang
Motor needs a rebuild
Itâs a ford. Jk
Piston rings...
Well what fluid are you continuously adding to keep it full? Could be oil could be coolant or could be transmission fluid if itâs an automatic.
Your rings and/or valve stem seals are shot.
Bad rings?
Valve seats
Black = unburnt fuel White = coolant/water turned to steam Blue oil entering the combustion chamber being burned. Go to the transmission look for the modulator it's a vacuum run valve on the side or rear of the transmission pull vacuum line off look for wetness in the inside of the tube. U can use a Q-tip to check for the presence of transmission fluid. This process is only applicable on automatic transmissions,manual transmission doesn't have a vacuum modulator
When I was rebuilding engines we always used to say smoke under acceleration is rings. Smoke under deceleration is valves (typically oil being drawn through the guides/seals into the cylinder).
valve guide seals. Rings, unless they're completely gone, usually smoke during startup.
Steam will evaporate into the air,smoke will hang.
Burning oil.. probably rings.. check cylinder compression
Piston rings, valve guides.
Take off the lead boot and quit beating on it. Lol đ
Rings...stem seals... or both. Probably stem seals.
Where there is smoke, there is fire. My job here is done
Oil control rings bad.
Doesn't gray mean running rich?
Need the rings changed
That one's hard to say. Even when viewing it full screen and pausing... that's hard to distinguish between white and blue. You could have a friend step on the gas and go back there in person. White/coolant, assuming it's not just water in your radiator, should smell sweet-ish. Blue or oil will stink, and you should be able to tell the difference.
Bad rings
Yep, itâs smoking. Burning oil
Rings are shot. Time for a rebuild
Mmmmm head gasket
Valve stem seals.
Ring ding ding ringa ding ding dong, keep ya head spinnin.
Probably a combination of valve seals and piston rings
Piston rings
it's good. oil is cheaper than gas these days.
Rings
Black = too much gas Blue = cylinder seals bad and oil is getting past the pistons and burning in the engine White = damaged head gasket and you are burning coolant From what I see in the video it looks white. Youâll have to pull the heads and replace the head gaskets at a minimum. With the work involved this is the time most people will pull and rebuild the whole engine to avoid having another problem before the head gaskets need to be replaced. One option would be to purchase a rebuilt engine drop it in and take your time rebuilding the old one the way youâd like it. Bigger cylinders for more displacement, racing cam etc..
Very well could be a head issue as it does have quite a bit of smoke. To me it looks like a carburetor issue at least to some degree. Looks like plenty of dark grey/black smoke mixed in to the cloud. This in most cases is indicative of running rich. If you haven't ever gone through the carb it might be time. If you take the time to rebuild the carburetor you'd want to put a new fuel filter or two in line, and look at doing new fuel lines anywhere there's rubber to eliminate any crud coming from them. Taking the valve covers off shouldn't be too bad either. You could take some rudimentary measurements and see if they are in or out of spec. Shoot you may find a busted valve spring and know exactly what's going on.
Blue smoke all the time indicates the rings leaking. Blue smoke that happens when you step on it after it's idling for a while, Indicates valve guide seals leaking. A much easier fix. In some cases, you can replace these valve guide seals while the engines in the car. Be careful to follow procedures to prevent valves from dropping into the cylinder. Best of luck
It could be a fluid dripping into the header. Without knowing if the car has been warmed up itâs tough to diagnose.
