Why does my Ford Excursion have black smoke?

Last week it started pumping out quite a bit white smoke on idle/low speeds AND black smoke on acceleration. By black smoke I mean closer to dark gray/light black (it’s not rolling coal per say). filled up with new diesel the day before I first noticed any smoke (I don’t know if this has anything to do with anything but maybe a clue perhaps?)

What causes a car to have black smoke coming from the exhaust?

6 Most Common Causes Of Black Smoke From Exhaust 1. Clogged Air Filters 2. Damaged Fuel Injectors 3. Faulty MAF Sensors 4. Bad EGR Valve 5. Damaged Piston Rings 6. Engine Deposits

How can I get black smoke out of my exhaust?

Luckily, you can mix the diesel fuel with a detergent additive to get rid of these harmful deposits. The black smoke will disappear after a few days after you do that. 4. Get The Engine Rings Checked And Replaced If Damaged

What causes black smoke in the combustion chamber?

Piston Rings are designed to prevent the infiltration of engine oil inside the combustion chamber. If there is any problem with the piston rings, the engine oil starts flowing into the combustion chamber. The combustion of the mixture of this engine oil and the fuel delivers black smoke. 6. Engine Deposits

Why does my Ford F150 have black smoke coming from the exhaust?

When they fail, your F150 will emit black smoke from the exhaust as oil is burnt along with the air and fuel in the cylinder. A bad fuel injector can dump too much fuel into the combustion chamber.

Why does my Audi Q7 have black smoke?

They are really cheap, easy to replace, and often fix the black smoke problem. The EGR valve recycles exhaust smoke back into the combustion chamber to help reduce engine emissions. When the EGR valve goes bad these gasses have nowhere to go but out through the exhaust, and they appear as black smoke.

What can I do about black smoke in my car?

We always recommend taking a look at their filter first. They are really cheap, easy to replace, and often fix the black smoke problem. The EGR valve recycles exhaust smoke back into the combustion chamber to help reduce engine emissions.

What causes black smoke after an oil change?

The EGR valve fails due to carbon build up on the valve or it can fail electronically. When it goes bad, it can cause black smoke, loss of power, no start and a fluttering noise. Clean the EGR valve at every other oil change to keep it functioning properly.

How does a 6.0 liter diesel engine work?

The 6.0 Power Stroke diesel engine utilizes a single vane VGT (Variable Geometry Turbocharger), which is designed to reduce turbo lag and create better throttle response. When a turbocharger starts to fail it will have the same symptoms as a bad EGR valve.

What causes a no start on a 6.0L diesel?

Rough start, no start, and rough running conditions often occur due to the FICM, or Fuel Injection Control Module. The FICM supplies 48 volts to the two solenoids that control oil flow to the fuel injector. Excessive heat from the engine and vibration can cause the FICM to overheat or fail.

Where does the Ford 7.3 blow white smoke?

Ran great and no smoke. I live in Las Vegas but I bought the truck in Salt Lake City. And little while after the drive back to Vegas started with friends. Started to smoke white but we thought it was just because we were passing cold part of Utah.

Why do I get white smoke from my diesel engine?

White smoke occurs for one of three reasons 1. Raw diesel comes through the exhaust completely unburned 2. Water entering combustion chamber. 3. The temperature in the combustion chamber is too low. Now, let’s look at three scenarios. What is wrong really depends on the “type” of white smoke you have.

What to do if your car is blowing white smoke?

I’d fill the fuel bowl with a fuel cleaner or ATF and then put the new filter in and crank. HOPEFULLY it cleans the injectors out. But if it is an injector dumping fuel constantly, I would drive it as little as possible cause it can ruin a motor. I’d do the fuel filter and change oil too since the oil fires the injectors.

Why does my Ford F-250 have white smoke?

Figure 2. A coolant leak on a 7.3 liter F-250. If you don’t have a coolant leak, move on to Step 3. Oil leaks inside your combustion chamber can also cause white smoke. Check for oil leaks. If oil is leaking inside the combustion chamber, it can cause white smoke as well.

Why do I have white smoke coming out of my exhaust?

How to spot a leaky injector. If your truck is a diesel and produces white smoke while warming up, this is completely normal. Diesel trucks also produce smoke during the “cleaning exhaust filter” operation. If this is the case, there is nothing wrong with your truck.

What kind of smoke is coming from the tailpipe of a car?

Drivers must understand the concept of smoke from cars. Usually, it is water vapor or steam, since it is introduced into the chamber. For that reason, you will have the water dripping from the tailpipe. Drivers can also see the water in the fuel or a leak in the head gasket.

Is it possible for a fuel filter to produce white smoke?

Yes. If the fuel is contaminated with water or some other foreign material it is possible that it will produce white smoke. The best way to test the fuel is to pull the filter and put it in a clear glass. Wait a few minutes and see if there is any separation. Can air in fuel cause white smoke? Yes. This is another common cause of white smoke.

Why does my Ford F-150 have white smoke coming from the exhaust?

An F-150 or F-250 that’s running well should not be pouring white smoke every time you get on the gas. This diagnostic will tell you what to look for if yours is smoking more than normal.

What causes white smoke in a 7.3 liter F-250?

If you coolant level is low and you know you’re not burning fluid, check around the coolant lines for signs of leaks. Figure 2. A coolant leak on a 7.3 liter F-250. If you don’t have a coolant leak, move on to Step 3. Oil leaks inside your combustion chamber can also cause white smoke. Check for oil leaks.

Why is there white smoke coming from my diesel engine?

In the cold weather, the white smoke can be quite normal, but in some situations, it is not. Continuous white smoke while driving is one of them. If you are having a diesel, white smoke may be unburned fuel or coolant going through the engine. But mostly, it is the incorrect injector timing in the cylinders.

What should I do if I have white smoke coming from my exhaust?

In order to fix it, drivers have to remove the intake manifold and examine the intake gasket. If there is any leak or rust, you know where to repair. If it is fine, we move to step number 2. Remember to only perform this step when the intake gasket is working fine. After that, we will come to the head gasket.

Why does the exhaust smell like burnt oil?

The exhaust will also have a burned oil smell. If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell. In this situation, you can pressure test the cooling system if the coolant is low or the engine has been overheating.

Why does my diesel engine have white smoke coming from the exhaust?

Newer electronic diesel engines with common rail injectors simultaneously match the speed of the turbo with the metered flow of diesel fuel into the cylinder. White smoke coming from the exhaust usually points to one point of failure: the injectors. Usually, white smoke indicates that the diesel fuel is not burning correctly.

When to shut down a diesel engine with smoke?

No matter the color of the smoke it is not something you should ignore. A properly working and maintained diesel engine should produce no visible smoke. Make sure to shut down the engine immediately if you encounter excessive smoke as further heat or load could severely damage the engine further.

What does Blue Smoke mean when starting an engine?

The presence of blue smoke is an indication of burning oil. Blue smoke should not be ignored but is common when starting an engine in a cold weather. The oil thins out when it is cold and some could escape into the cylinder and be burnt.

Can you see white smoke from a diesel engine?

White smoke in diesel engines is usually the last color you want to see, particularly on gas cars. If the smoke is thin, and goes away relatively quickly, than it is merely condensation. However, thicker, longer lasting smoke is a much larger headache.

What does blue smoke from a diesel truck mean?

Gray or Blue Smoke from Diesel Exhaust. Newer, low mileage truck owners can skip this paragraph, but many of us like to have a worn out beater truck laying around, or maybe your teenager bought their first car from a not-so-honest guy. Blue usually means one thing: you are burning oil.

What causes white smoke to come out of exhaust?

Your engine is more than likely burning coolant. This can be the result of a blown head gasket, damaged cylinder head, or cracked engine block – none of these are easy on the wallet. Diesels can also put out white smoke when fuel passes completely through the engine and reaches the exhaust without having been burned.

What kind of smoke comes from a diesel truck?

Let’s talk about the different colors of diesel exhaust smoke, their causes and solutions. Gray or Blue Smoke from Diesel Exhaust. Newer, low mileage truck owners can skip this paragraph, but many of us like to have a worn out beater truck laying around, or maybe your teenager bought their first car from a not-so-honest guy.

Why does my 2004 F 350 blow white smoke?

I have at 2004 f 350 nothing has been done to it yet and about 5 days ago it started blowing white smoke out of the tailpipe this is my first diesel truck that I’ve owned people are telling me it’s the EGR what should I do I lose power and white smoke comes out tail pipe.

Why do I get black smoke from my engine?

Why do I have black smoke coming from my tailpipe?

If there is a lack of of air coming into the engine, the fuel will be burnt partially then leads to black smoke from tailpipe. Fuel needs to be burnt fully as it will only emit CO2 and water, which do not cause black smoke. That is why the correct combination of fuel and air is so important if you want to avoid black smoke.

Are there any problems with a 6.0 liter diesel engine?

Below are the most common problems associated with the 6.0 Power Stroke engine. The 6.0L Power Stroke fuel injection system operates on oil pressure, very high oil pressure.

What are the symptoms of Ford 6.0 power stroke FICM?

Calibration concerns, powertrain component faults and FICM malfunctions may produce similar drivability concerns. NOTE: The most common symptoms of a failed FICM are: NO START or CONSTANT MISFIRE AT ALL ENGINE TEMPERATURES. Symptoms other than these are not likely to be caused by the Ford 6.0 FICM module.

Why is my Ford 6.0L Powerstroke not working?

Ford’s 6.0L Powerstroke came with Hydraulically actuated electronically controlled unit injectors (HEUI), similar to the 7.3L Powerstroke. These injectors are prone to static friction, or stiction, which is the result of carbon and sludge build up within the HEUI injectors’ spool valves.

What does it mean if your car is losing coolant but no leak?

However, you may breathe easy if the mechanic does not find any trace of exhaust gases in the coolant. It means that the liquid has not reached the engine yet. The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid.

What happens if you lose antifreeze with no apparent leak?

Losing Antifreeze With No Apparent Leak. Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.

Why do I have white smoke coming out of my tailpipe?

Higher operating temperatures are a typical symptom of a clogged EGR cooler. These higher temperatures commonly cause head gasket failures. The EGR coolers commonly leak coolant into the exhaust, resulting in white smoke (Steam) exiting the tail pipe. The Engine oil cooler is commonly the cause of EGR Cooler issues.

What does black smoke mean on a PowerStroke?

Smoke is the easiest way to tell what is wrong with a PowerStroke fuel injector. White smoke is normal on startup, but excessive white smoke could mean a loose injector or low compression. Black smoke is normal on hard accelerations, but excessive black smoke means the fuel-to-air ratio is too high.

What does black smoke mean on hard acceleration?

Black smoke is normal on hard accelerations, but excessive black smoke means the fuel-to-air ratio is too high. Black smoke can also be attributed to restricted intake or exhaust, or a leak in the intake hose.

What causes a 6.0L Turbo to fail?

Early 6.0L Powerstroke trucks also suffer from a poor oil drain tube. The collection of oil in the turbocharger can result in the oil cooking. This has been the root cause of many all-out turbocharger failures in the 6.0L Powerstrokes. Ford gave ’06 and ’07 models an improved oil drain tube, resulting in drastically less turbo failures.
