My 2011 6.7 has a strange tick when I accelerate once I speed up it goes away it happens in drive or reverse I only have 29000 on the truck it will tick one to three times and then stops I had new rear u joints put on and is still ticking and is driving me crazy u can only hear it with windows down ....
View 14 RepliesRecently purchased a 2005 F250 6.0. I noticed that sometimes when I brake it feels strange...like ABS activating in rear or something. Usually at 15-30mph when braking right after accelerating. Its a bit difficult to explain. I'm planning on getting a break inspection soon.
View 3 RepliesI have a 2011 F250 6.7 Turbo Diesel I recently purchased. I am hearing a noise when accelerating from a stop. The only time I'm hearing it is when the window is down. The noise sounds like someone is tapping an aluminum pop can. It is easily reproducible as well. I decided to get under the truck and have my wife toggle the transmission from park to reverse. They noise does not occur unless one foot is placed on the brake and the accelerator is lightly pressed. (My wife had the opportunity to run me over and claim it as an accident but lucky me she decided not too). Below is a video. I had a hard time locating the noise. It sounds like it may be coming from the exhaust or drive shaft. The drive shaft does not spin when toggling from reverse to drive but the ticking noise can be simulated and heard when lightly pressing the gas while holding the brake. Something need lubed somewhere?

So my 2015 has a touch over 1K miles on it. It has "ticked" loudly since day 1. I generally keep my truck in my shop and hear the ticking every single time when I pull it outside. It occurs immediately after start up and happens at idle. Easily heard anywhere around the front end of the truck. This is not the normal diesel engine noise and absolutely sounds like the tick-tick-tick of an old typewriter.
So in doing some research, I came upon the TSB for put out for the 2011-2014 models, in which it CLEARLY states the typewriter noise can/will occur AFTER an oil change and eventually go away...
So, is the noise only supposed to be heard AFTER an oil change, and if so, why would my truck do it even though it has not had an oil change?My 2012 did not have the tick before, during or after an oil change, ever.
Coming home from a trip with my truck pulling the 5th wheel, we heard noises that seemed to be coming from the front hubs that sounded like stones in the hub caps. Once we got home I pulled the front lug covers to see if any came loose and were rattling around inside, but all were torgued properly. Everything drove strait and tight with no noticeable problems, should I be concerned....
View 8 RepliesI've had good running on the truck but lately in the cold the idle has a weird skip to it like it's missing on a cyl. It will start fine, and run fine for about 30 seconds. Then it will start to mis. When giving pedal it goes away and it's driveable but it doesn't sound right. After a bit of running it's fine for the duration while warm. My monitors are I think all good, 48.5v, icp about 1250 psi. Is this the famed "injector stiction"?
View 5 RepliesThe truck always made a few strange noises after shutdown, but this is new and annoying.
Here's the scenario: Truck is warm and no CEL. A few seconds after shutdown, I hear all the normal(?) noises and then a noise that sounds like a vacume pump running starts and continues for about 20 to 30 seconds. Cycling the key, but not starting the motor will cause the noise to happen again and again on each key on/off cycle.
The noise seems to be coming from the top front of the motor. Could this be fuel pressure bleeding off? Is there a check valve that is maybe not doing it's job??
One of the many things that impresses me about the 6.7 is how well it lugs...... it'll run right down to near 1,000 rpm in 6th gear and stay there till it absolutely has to shift. Like a diesel should. Well, recently, and now more frequently my truck is making some strange noises when it lugs down. It'll mainly do it if I'm towing light, like my flat trailer empty, or maybe if I have a decent load in the bed. But occasionally it'll do it empty. As soon as it lugs down low to 1,000-1,200 and pulls there for a few seconds you'll hear a couple squeaks, then a kinda chugchugchugchug noise. It immediately quits if you let off or make it shift down. It sounds like a turbo-related noise, but I don't really know. Truck only has 9k miles on it. I just know this is one of those things I'll take it back to the dealer and they'll give me the ol "we can't duplicate the problem here." What it could be?

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.
I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.
View 14 RepliesWhat could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.
View 4 RepliesI have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?
View 2 RepliesIt's a 2006 Ford F250 6.0 diesel with 307,000 miles on it. Up until a week ago it ran great but when I was in a drive thru I turned it off (to order) then turned it back on to pull up but the idle was very rough and the truck shook as I revved it up but it went back to normal after I saw a puff of white smoke. Ever since then every few stop lights I will begin to accelerate but there isn't any power and it shoots out a lot and I mean a lot of black smoke for a second then the turbo spools and it's normal.
Today though I turned a corner and began to accelerate after but I had no power at all it shot out an un manageable amount of black smoke mixed with very little white as I pressed the pedal. I put the pedal to the floor and the rpm were up to 2000 still no power I out it in tow hail still pedal to floor and now power! At this point I pulled over and called my dad figuring the truck wouldn't move anymore but I got no answer so I tried to go again seeing how ideas almost and and the truck worked fine small amount of lag but it ran made boost and worked until I got home. What could it be? I've heard maybe my turbo is bad maybe my egr valve but I'm just not sure.
I have a 2013 that randomly stutters or cuts out for a second while accelerating. This happens whether I am slowly accelerating or full throttle. This used to happen once every few months but it is happening more frequently now. It will randomly happen while trying to accelerate on the freeway. The truck feels like it stalls, then takes off. It feels like it loses boost pressure so maybe a wastegate issue or possibly an EGR valve issue. No codes are set.
View 14 RepliesBack again.. I just replaced the HPOP and IPR valve on my truck a few weeks ago. While the turbo was out I cleaned it and applied a small amount of anti seize on the unison ring. When installing the turbo I had moved the y-pipe a little to get the turbo in place. About a week after it was running again I started to get a squealing noise under acceleration. The noise isn't a whistle like the turbo but an actual squeal. Its a little bit louder than the turbo whistle. If I am in park and rev the engine it doesn't happen. It only happens when I accelerate and seems to be when there is boost. If I let off the gas pedal the noise stops. I don't have an issue with making boost. I did replace the turbo boot when it was apart a few weeks ago so I don't think that is the problem I checked the y-pipe clamp and down-pipe clamp and both are fine. I replaced the serpentine belt this past weekend and checked all pulleys, they were all very good with no play. Another thing, the pitch of the noise seems to change with rpm's too. What could be causing this type of noise?
View 14 RepliesWhat could be causing my turbo to be fluctuating while accelerating? I can definitely hear the difference in the sound of the air and today while towing my camper I could even see the dash gauge bouncing around some.
View 8 RepliesPurchased 2011 3 weeks ago. Due to not paying attention, put gas in diesel. Had tank dropped and drained but after reassembly, fuel gauge inop. When turn ignition switch on, get normal sweep of all dash gauges but fuel gauge does not read. 2nd tech says sender okay, must be gauge. Dealer ssays if it sweeps, it isn't the gauge. 011 F250 6.7L.....
View 7 RepliesSo This all started when I noticed my 03 Ex 6.0 started to not upshift every once and awhile.It has 300,000 miles on it.As far as I know it has never had tranny filter changed.So I said it shall be done.I did both internal and external filters and the fluid was very dark but not burnt.The pan was very clean and no sludge or metal on magnet.Put in new fluid and ran the truck until warm and checked fluid level and all was good.Now this where things get weird.Went for a drive and truck would not up from first easily or I had to feather pedal to upshift. If I put my foot into it I got a lot of black smoke after about 5 seconds and some sort of shuttering in the engine on deceleration. Ran AE for codes and nothing came up. The engine has EGR Delete. Blue spring, new injectors, glow plugs......
View 3 RepliesMy truck recently has been giving me the issue of wither having no boost , bogging down as its trying to excelerate , then going into overboost. It idles fine , i have cleaned out the egr . I'm at a complete list on what to do at this point the truck is a 2007 F250 6.0l
View 4 RepliesSounds like an air leak when accelerating, and constant at mid/higher rpm's while driving. Hard to tell when parked.
View 2 RepliesDuring 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.
