I didn't notice anything until I was towing yesterday and tried to pass a car to get onto the offramp.
Anyway, I went to floor it so I could get around and, in my mirror, I could see a decent bit of grey smoke coming out. What could it be?
It doesn't smoke at all on startup and runs smooth right away.
I replaced the rings on all 8 injectors put in 8 new glow plugs and a relay. My truck is still putting out grey/ white smoke at start up. It goes away after about a minutes. Truck runs a little rough a first then smooths out. I know some smoke after doing a job like this is to be expected but I was thinking I t would go away by now. I've been running through my head what I might of done wrong but I can't think of anything.
Does it just need all new injectors and not just rings ?
2001 f250 7.3
Recently I have had many problems with my 2000 7.3l .... The one I cant get rid of is the p1316 code. I have changed out the uvc harness and gasket with new ones, then removed valve cover's to double check connections again and they are fine. I am getting white smoke and the truck misses. I do not have a advanced reader for the codes just using my edge programmer. I have also disconnected the battery and cleared the code but it comes right back.
View 14 RepliesObviously its not a good thing, but this seems a little severe for a truck that hasnt had any issues prior. The truck is a 1998 F150 4.6 and was running just fine until POP!! A puff of grey smoke coming from the throttle body and followed by (obviously) a rough idle. So basically, I know that any metal fragments were directly sucked into the intake and based on the size of the chipped area (roughly 1.5cm). I am wondering what type of internal damage this would (or already has) caused.
View 3 RepliesI have a 02 power stroke 7.3, driving down the road the other day is started smoking a grayish white smoke pretty good. i let off the throttle and it had a real loud knock along with the smoke. oil pressure was good. i stuck it in neutral and revved it up kept smoking but the knock would go away at higher rpm. then all at once it would stop and run fine. then today it started doing it and wont stop now at all.
View 14 RepliesJust picked my 2005 excursion from being bulletproofed. Arp studs, oem head gaskets, turbo cleaned rebuilt, blue spring mod, 8 new Motorcraft injectors, rebuilt heads surfaced, new Ford oil cooler, egr plugged delete, sct x4 on 2nd tow tune, new radiator, new fan clutch, new water pump, and sinister delete kit. I got almost home to last stop sign and took off and noticed grey/white smoke.
Then drove so more for 20 minutes. Everything you come to complete stop and take off it does this. On start up it will puff a little puff then go away. Is this normal after a rebuild and go away after some miles have been put on engine. Or should I be worried. It runs awesome now and idles so smooth with tons of power on tow tune.
I would I have a 01 7.3 e350 with 111k miles. I drove the van a couple of days ago.it sat for 2 days and now it wont go past 30mph.the van shakes crazy and went when i hit the petal no power with smoke coming out the tail pipe sometimes. When I shut the van off and restart it to drive it,it sounds better. I changed the fuel filter with motorcraft and changed the oil. Here is the kicker. It ran good after I changed the fuel filter the whole day and now its 4th of july and I went to get some drinks and it happened again.
View 11 Repliesok so about a year ago and 7 thousand miles ago (abouts) I did a engine build and rebuild I had brand new injector cups, injectors (180/100's) and new o-rings......now I've got fuel in my coolant and smokes like a freight train in the mornings white/grey I believe (its dark) but never black smoke but not the smell of coolant like unburnt fuel truck starts up amazing at 10 degrees' when I had the machine shop building my heads for my stg 1 cam I had told them not to install my cups well they did anyways and used red locktite when I keep hearing and seeing recommended to use green and have used green in the past
I know most situations are cracked cup, cracked heads, my biggest question is ya think the red locktite will hold? And since the cups are new could it be a injector o-ring? dosent the fluids on the injector go botton to top (coolant-fuel-oil) and a bad oring mixing the two I did notice my fuel psi was sittin higher liker 75 psi iv lowerd it since then
SO, I've owned a 92 f250 7.3 for 10 years and it's got over 340k miles on it. Well, she is getting tired so I'm debating replacing the truck with a SLIGHTLY newer model.
I've found a truck that is a 99 7.3 powerstroke with a 6 speed manual and 260k miles. Knowing these engines I feel this truck has at least another 100k in it if the thing was somewhat taken care of. The issue is that the fella that has it for sale says it ran great for years and one day started blowing white smoke while driving. Other than this new issue it runs fine.
So my question is, what could be the issues causing the white smoke? I always thought white meant unburned diesel or maybe antifreeze. Head gasket comes to mind but it's not something I've ever dealt with.
I like that he parked it when it started having issues. Sounds like someone who doesn't completely trash their vehicles. Too high given the condition? Truck looks and sounds pretty good aside from the smoke, pretty reasonable condition.
my 2000 f350 7.3 is acting strange lately. Its got 252k and is all stock other than exhaust,intake,ww2. It smokes white every random once in a while for some reason. At start up it wont though. If i get on it every once in a while it will smoke white then go to back to black. Im not consuming coolant, and the oil looks fine, no residue on the oil cap and its not puffing out the oil cap either. Other than that its running great just dont know why it goes white every so often.
View 14 Replies2000 F350 with 340000 on it, have had it for the last 140000. It's an old service truck from south west gas with one owner in between them and me and he put about 5000 on it. I have the big cylinder open air filter, billet compressor wheel, 4" exhaust all the way and an Edge tuner. Don't have any codes I can pull with the tuner. Have been good to me so fare only need regular maintenance, but always had smoke out oil filler with a little pulse.
2500 ago I changed oil and add 1/4 of Lucas oil. 3 days ago when I started in the morning it smoked white smoke out the exhaust as a steam train and idle rough, but cleared up as I went down the street and will do so every time I start cold or warm. Ok, might need new GP, did that yesterday yet the same. Now I start checking stuff and have smoke out the oil filler as a steam train so the cap won't stay.
I know it sound like alot of problems, just try to verify some of them. The smoke out oil filler is blow by? The smoke on start up is that related to bad injectors? Can a bad injector dumping fuel create the blow by? Coolant level ok Transmission fluid level ok Engine oil Rotella T6 added 3 quarter in 2500 miles. I do not have a scanner or any other advance test tools.
I have posted a pic of a smoke issue I am having while pulling.
I just pulled a 10,000 lb trailer up a few 7% grades at 8-10,000 ft and the best I could do was 40-45 mph at 6mpg. Every hill would set a P1211 and when the truck downshifted to 3rd the smoke would go away for the most part.
Truck is 100% stock and pulls the same as my F350 with 3.73 gears but smokes a lot more.
The smoke is kind of annoying and performance seems sluggish especially given the 4.88 gearing. Where to start?
Has new ipr, hpop, icp, fuel filter, air filter, fresh 5w40 mobil 1.
I have a 2003 Superduty with 193k miles that is bone stock. I sold the truck to a friend and when he decided to not pay the remaining balance on the truck, I took back ownership. The truck was having heating issues and it set at a mechanic shop for nearly 2 years waiting for a diagnosis on the heating issue. Fast forward to the present and I now have the truck at my home. Heating issue was the radiator but this is no longer a concern. When I went to pick up the truck from the mechanic, the truck started fine. Every other day for the last 4-5 weeks I would start the truck with no problems.
I get the truck tagged and start driving it on a daily basis. I've put several hundred miles on it but the more I drive it, the less it wants to start. Now it's to a point where it only cranks but won't start. I can take a gas rag and hold it in the intake and eventually it will start. Once it's running, it runs great and has no issues starting. But once it sets for 3-4 hours, it won't start without some sort of assistance.
While trying to find the issue, I've found and repaired 2 fuel leaks and in the process I replaced fuel filter, air filter, replaced glow plug relay, replaced batteries, replaced CPS. Fuel pump is working fine. I've tried the ICP test and doesn't make a difference.
The glow plug light or WTS light works so don't think its the GP. The CES light was on. Had it scanned and it was the air bag sensor so no support from the CES.
While I was working on it yesterday and after cranking on it for 5-10 minutes, it would act like it was going to start and black smoke would be coming out from the exhaust. I let it set to cool the starter it fired up like it had no issues.
I have a 2001 F-350 w/7.3. There was excessive smoke coming from the exhaust. So the first thing I did was to pull the glow plugs to see what they looked like. and while having them out I cranked the engine over. Upon doing so I noticed 1 cylinder putting fuel out of the hole. Meaning it was like you could put your hand about 6 inches above the hole and your hand would be wet from fuel. None of the other cylinders was like that. So what I did was pull the injector from the cylinder next to it and put it in to see if it was the injector failing. But it was still doing the same thing. What would cause this??
View 3 Replies2005 6.0 133000 miles... Truck has been stuttering and running rough for about 2 weeks, warms up and is somewhat better. Would stutter in the RPM range of 1600 to 2100 RPM, can push down on accelerator and power through it with no problems. Checked codes and got PO269 Contribution Cylinder 3. Changed all filters and oil change along with a bottle of hot shot secret in the oil. Truck is now blowing blackish grey smoke under throttle and when idling that smells like fuel. No coolant in oil, and no oil in coolant.is the injector shot, or injector sleeve bad?
View 6 RepliesPicked up my 5th wheel this afternoon from being raised 3". Dropped over the 10 percent grade down the hill to normal driving. Had the trailer brake controller to boost #2 (Prodigy controller). Had to brake pretty continuously, (tried to stay off it a bit, but is is about 10 grade for about 3/4 mile. Put the auto trans in D2 to get brakes come to the red light at the bottom. Noticed a puff of smoke at the front. Driver side, didn't notice passenger side.
New pads and new slotted rotors new maybe 1,500 miles ago. Not liking that action, but need thoughts. Want to put a thousand or 2 miles towing this summer and accompanying mountainous terrain and back.
2000 F350 Lariat Super Duty 7.3 4x4 NOT a dually.
Having trouble with motor, driving home one day heard a noise under the hood. Then a lot of grey smoke started coming out of exhaust. Got the truck hauled home notice fuel was coming out at the number 7 cylinder at exhaust port. Thought it might be the injector just put rebuilt ones in, thought I might have received a bad one. I switch the number 7 injector with the number 3 injector. Did not make a difference still have fuel leaking out of exhaust manifold at the number 7 cylinder and a lot of grey smoke coming out of exhaust. Not sure where to start looking next? Could it be the injector cup is the problem?
View 14 RepliesI just came back from a 200 mile trip and parked my truck. Next day, got in the truck and turned the key.... it turned over and white smoke coming out the tail pipe. After doing some research(you tube),I ruled out cps sensor because it was showing low rpms on tach. Replaced glow plug relay and still have same issue.. what else to look at that I can do without getting it towed. Hunting season coming soon and I need the beast.
View 14 RepliesBeen barely driving my super duty due to it having a multitude of issues. So working on getting this thing back to some semblance of running decently and it has been smoking whitish blue, oil smoke out the exhaust. Not constantly, intermittently as far as I can tell.
If I drive it at highway speeds for 5-10 minutes then slow down it will smoke for about 10-15 seconds pretty heavily. Yesterday I got off the beltway after running for 15 minutes, it didn't seem to be smoking, but about 1 mile to 1 and half miles later, pulled into a convenience store and it was like I was spraying for mosquitoes for about 20 seconds then cleared up.
Truck seems to be running strong. Turbo doesn't seem to have any play side to side or in and out(according to Baltimore Performance Diesel who I don't necessarily trust at all [ I will explain my reasoning on that some other time, but let's just say, one of the reasons involves a rear main seal diagnosis... I digress] but I assume they are correct on that, I haven't looked myself. So what are some other possible answers, rings I would think would be fairly constant but I could be wrong there.
Truck is a 02' F350 xlt crew cab, 7.3l, 4x4, 4R100, manual transfer case, 125,000 miles.
So me and the family were pulling out of the driveway tonight and electrical smoke starts blowing out the vents. My wife had just plugged a cheap USB charger into the auxiliary outlet above the cup holders for only 30 seconds. I immediately pulled back into the driveway, yanked the charger out, and found it had melted a hole in the side of it. No smoke had come from the charger or the outlet. The outlet looked fine and wasn't hot to the touch. I pulled the dash off real fast and started grabbing wires, feeling for anything that was hot or melting. I couldn't find anything.
I pulled the cover off under the steering wheel and couldn't find anything. I never turned the truck off while I was looking. After a few minutes, I noticed that the cover over the fuse panel was warm. Pulled the cover off and felt every fuse end and they were all cool to the touch. The relays in the middle were all pretty warm(almost hot to where I couldn't touch them). I was still faintly smelling the burnt smell and I couldn't tell if it was just stuck in my nose. I disconnected the batteries and we had to switch cars(heading to a bbq).
So I just got home and I'm going to start looking for any obvious signs first. What could be going on at the panel? So far, everything is still working. I haven't found any blown fuses.
Ok I'm working on a 2000 7.3 on a F550 truck was running but had no power so we changed out all the injectors and glow plugs and rebuilt the turbo now there is no start it turns over and were getting black smoke from the tail pipe. What is going on with it?
