Ford 6.7L Power Stroke Diesel :: 2011 F350 - Black Smoke When Under Hard Acceleration
Jul 5, 2015
I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.

2007 F-350 6.0L, Wife phoned and said that the truck backfired a couple of times and there was black smoke from exhaust. When she stopped at idle there is now alot of white smoke but coolant level looks fine. She has about 200 km's to go before she is home pulling a 20 foot horse trailer with 1 horse.

After running perfectly fine all day my truck will seem to bog down and when I press the accelerator the reaction is extremely delayed and tons of black smoke will come out of the tail pipe before the truck actually gains power and takes off. The check engine light has been coming on but will turn itself off after the truck has been shutdown a few times....

My dad has a 04 f350 6.0 and on his way back from a trip he filled up and drove 60 miles and it started smoking white smoke, after he let it sit a while he added fuel injector cleaner thinking it might have been somewhat bad fuel. Drove it 20 more miles and it it changed to black smoke and started sputtering like it was missing. Blowing a lot of smoke. Took it to ford dealer and they checked for codes and it said the #8 injector was bad and needed replaced. My question is would the injector going bad cause all the smoke and missing?

Well my problem went from bad to worse. My 05 started running rough at idle, then smoothed out a bit but started smoking on acceleration a little. At this point it felt like it had more power than ever before and even ran smoother running up to 3k RPM before shifting (manual transmission). But now it's smoking so bad, I can't really drive it. It's smoking white or gray at idle but blowing black smoke on acceleration. I had a cylinder 5 contribution code but with the amount of smoke it's hard to believe only one injector is a problem. I pulled the EGR valve and it doesn't look stuck open but I'm going to replace it anyway.

So I've been having issues with starting my truck lately. It was really hard to turn over, would start really hard when it did and would blow some black smoke. Turns out my starter was bad so I replaced it with a DB Electric high torque starter. Now it starts up great... for the most part.
I'm still having some black smoke when it's a cold start and/or I have the key set to "On" to warm the glow plugs for a few seconds. It's almost like the starter is turning over the engine, but for the first few turns it sounds empty or hollow (at least that's the best way I can describe it). After the first turns it will sound normal how it's supposed to and will fire up shortly after but with some black smoke.
If my car is already warm it cranks right up without any smoke unless I have the key set to "On" for a few seconds to warm the glow plugs like I said earlier. Pretty much if I warm the glow plugs it makes it harder to start up for some odd reason.
What might cause this or how to fix it? Maybe some of my glow plugs are going bad, or possibly my IDM? I used to have the P1670 code by itself, however, that went away when I replaced the starter. I also just replaced my camshaft position sensor just to be sure it wasn't going bad. I've also been having some boost pressure leaks if that's relevant at all.

I have a 2003 F250CC 7.3 with 200,000 miles on it. I just purchased this truck about a month ago. My question is it blows black smoke. A little at idle but mostly when you give it any pedal. I have replaced all of the injector o rings and that didn't make a difference. Then I had it tested and it failed a CCT test on #2 cylinder. I have an injector to put in it, but am curious to find out if 1 bad injector would be enough to make it smoke all the time. I keep getting P1211 ICP pressure above desired. I had a friend of mine who used to work at a ford garage take a look at it with his computer and he said that everything looks good other than the CCT test.

Started with lots of black smoke all of a sudden. Not under any significant load at that time. Reached destination (barely) and started the search. Have taken off blue connectors on CAC passenger side. Top is marginal but see no holes. Pulled the MAP hose and see nothing unusual. Have not checked the driver side CAC or the BPV sensor. Have a ScanII device that shows no codes. Got my other scanner and it too shows no codes.
Had it towed home over 100 miles 'cause now it just barely runs. Idles fine but have a engine noise change (deep and hollow) every once and a while at idle. EGR leak? Doesn't blow black smoke anymore. More of a white/blue. Exhaust smells odd. Absolutely no turbo activity. When shutting hear no whine down of the turbo. No boost evident on the dash or on the scan II. I am at a loss at this point. Will check fittings again.

Was hauling a bobcat this AM and noticed something odd in my rear view. Under steady accelleration (either light or heavy foot pedal pressure - steady either way), the exhaust would puff out sporadic extreme dark clouds of smoke. The puffs weren't fast like every cylinder rotation.. but every second or so.. puff of very thick black smoke mixed in with the expected black smoke we see.
Truck has 350k miles with regular oil changes. Year ago someone hooked the injectors up to the computer software (buzz test) and all of them checked out to be in very good condition.
The same tech pointed out some dark blowby at the uppipe on the back of the engine. Other than that the truck is in pretty good condition for its age. What could the sporadic very thick/dark puffs of black smoke indicate?

6.0. 115,000 miles. Everything stock, except bully dog intake filter.
I replaced the FICM recently, with one that I bought from the guy who makes those cool You Tube videos, Diesel Tech Ron. I also replaced the EGR valve. I also replaced the intercooler boots on the hot side. I cleaned the intercooler pipes. I cleaned the intake filter as well. I'm still blowing out black smoke, if I floor it when I need to pass someone.
Follow up question: I bought those boots from Riff Raff Diesel and I bought new clamps, too. I'm not sure if I installed correctly. It's already blown one off (it blew the top of the intercooler pipe off, by the turbo, but the boot stays on the turbo) and I put it back on and tightened it all the way down, and I've had to re-adjust 2 times, now, since it acts like it still wants to slip off. Do I simply have the other ones misaligned???

So I started to NM from fort worth texas with my 33" camper blew my CAC pipe four times. Finally got there. In the morning it took longer than expected to start. When it did white smoke. That was replaced with black smoke under full throttle.
I went from elevation of 700 to 8000 Ft. Should I care about black smoke? Meaning should I take it to Ford and get a rental car to get it looked at for our trip home.
96 degrees towing at 70mph with lots of climbing mountains.

1st Ford was an '08 to '10 model F250 6.4L that had an engine fire on I-82 towards Ellensburg in the passing lane.
2nd Ford was a 2005 F-250 6.0L at Vantage, he had black smoke coming out of the exhaust and a terrible engine knock, and was pulling a 32 ft TT. When I went to go talk to him, he had no idea what a ScanGauge was or anything about the truck.
When I looked at the engine bay with him I saw the EGR valve had been deleted with a block off plate and not plugged into the fan hanging on the side anywhere, he had the high rise aftermarket oil cap installed, ALL the metal/aluminum parts had bad oxidization. He had no gauges whatsoever.
Then to top it off, he said he was going to try and make it to Ellensburg while pulling his trailer. I told him he had a 4% grade for 10 miles in front of him to climb, and the another 35 miles after that on flat ground. All I could feel was, "is there any hope for this guy"?
Anyways, my question is, without any gauges, what would be some good educated guesses with the black smoke and knock? I am mostly just curious what this guys issue might of been with his truck since seeing the symptoms first hand.
My thoughts are the oil cooler leaking, and making the injector(s) stick open.
Of course now that I think of it, there's probably too many scenarios to mention.

Driving home 2003 6.0 started blowing a ton of black smoke, cars wouldn't get behind me. Found an exhaust leak on the driver side up y pipe. Would that cause this much smoke? 2 codes were 0284 and 0281, I replaced those injectors about 10k ago, at the same time replaced turbo, hpop, egr valve and cooler delete, and new oil cooler.

Found a 2004 Ex, Eddie Bauer edition says it has injector issues, blowing black smoke........ It is apart cause he thought it was the EGR. Has 245,000 on the clock. If the body is super clean I'll give him a offer, it's going to get a motor either way and I'll have my Ex back.............I really miss that truck!

Today I was riding along and all of a sudden I noticed a loss of power. I look in the rear view mirror and get into the pedal and a lot of black smoke. When I get to where I'm going and stop I noticed the idol was a little loopy. I never saw a check engine light. I have the Edge insight. I had two codes. P1000 OBD System readiness test not complete. P2290 ICP TO LOW.
When I would reset the codes the P1000 came back instantly every time. I parked the truck for about an hour. When I started it back up everything was normal. The power was back and no smoke. This happened two more times throughout the day. I have heard people describe a sticking EGR Valve causing these symptoms. Is that where I should start looking or is the ICP the culprit or something else?

I have a 2003 with 150k miles. My 6.0 has black smoke and can barely crawl up a hill. Dealership is 30 days out for an appt. Air filter, oil change, alternator, and batteries are new. I removed the EGR valve and cleaned, but the valve seat is not perfect. I can see 20 to 30 mil gap around half of the seat. Is this ok or will that little gap cause this?
Hoses all look good. No alarm lights. I have no diagnostic tool but I can use a meter well. It did have an airbag light but I found the fuse missing and replaced it. The air filter alarm switch fell apart but I bypassed it till I get new part. No alarm lights now.

So I am not sure exactly what is going on with my truck. It is a 2004 F250 has a 6.0 L. Sometimes when I take off from a stop the truck has no power and blows some black smoke. Then the turbo kicks in and all is fine. It comes and goes when it pleases no matter the temperature. What started happening is when I drive it a steady pace on the highway sometimes the turbo gets quieter and louder and quieter and louder sometimes when it gets quieter I see a little bit of black coming out of the tailpipe. Sometimes it doesn't do it at all. Also sometimes when I let off the gas the truck sounds like it's trying to laugh at me like a wastegate is fluttering.

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

During an out of town trip today, 6.0L 2006 started burning black smoke when accelerating. Was bullet proofed in 2013 without replacing injectors. Running a SCT programmer. After getting home I connected the tuner and didn't have any DTC's. Checked the oil, didn't smell any diesel on the oil stick. I was running the street tune, so I changed to the performance tune and it doesn't seem to be smoking as bad. What could be going on? This site has always came through for me (a non mechanic) when troubles start.
