My 2011 F350 - 6.7 has developed this KRAZY thump, snap noise under the hood, loud enough to be heard inside the cab, and I cannot find out what the heck it is. It is not directly connected to the motor, you can rev it and the noise does not change. the thump is like, every few seconds or so, especially when the motor is cold. I am afraid this is a 2000 dollar noise and the truck is out of warranty.
View 8 RepliesI have an 06 f250 superduty, 6.0 . Last week I rolled into the throttle up to about 95 and then backed off. After which it developed a thumping noise, not metal, more like an air thump in the intake. Not throwing any codes, still runs strong, pulls boost, etc. The motor does have 285,000.
View 7 RepliesI have a code for #6 low contribution and a thumping noise out the exhaust. When I turn number 6 injector off the popping/ thumping goes away. Truck is straight piped and deleted. It started doing this after getting on it hard to get on the high way. Sounds like beating an empty pop bottle on something
View 14 RepliesI have recently bought a 04 f250 6.0, and it has the intake thumping noise that varies speed with idle... I was told it could be a broken rocker, a bent push rod, or a broken roller... I am not that much experienced with diesels. I've spoken to the dealership, and they don't wanna fix it, they said it wouldnt hurt it to drive it like that, but the noise bothers the hell out of me, and everyone notices it. so i wanna get it fixed. I am hoping its just a rocker. if it is just a rocker how deep am i in? truck has 240xxx miles on it, and runs perfect other than that noise.
View 7 RepliesI have a 2011 f250 6.7, I park under my house everyday, so I am used to weird noises coming from my truck when I shut it off, but now that I just did a dpf and egr delete, and tuner, I noticed that my tuner doesn't shut down until the noise under the hood stops, which takes a few minutes to stop, I use to hear the air valve on the egr cooler shut when every got quiet, but I don't remember it lasting this long, any one else have a H&S mini max and it doesn't shut down right away? the place where I bought my mini maxx said it should shut down as soon as your head lights go out, but that's not the case, the headlights go out long before this noise stops and the tuner powers off
View 10 RepliesJust pu my new 2013 6.7 Diesel with 1300 miles... There is a most annoying whining coming from under the hood and sound like its coming from the secondary filter area or turbo (you can even feel it if you put your hand on the filter lines and housing) and it starts a minute or so after the vehicle has been running and you can her in the cab at 70-mph... At drive through restaurants I have to shut the tk down to place my order and never goes away..

Had Just replaced glow plugs and batteries along with a new set of tires. Truck had been running fine for the three days that is was. Went out the next morning and went to start and "POP" a large noise came from under the hood. I have yet to discover where this noise particularly came from or what it may have been that caused it. But ever since the POP it will not turnover what so ever. Key on every thing is normal all power just when go to turn key over it makes a faint click. You can feel the click in the relays on your hand when you try to turnover. But nothing. I am absolutely clueless.
View 14 RepliesMy 2011 6.7 just started making a hum noise after shutdown. I've read that it might be the wastegate solenoid. Is there a TSB for this. My truck is tuned so hopefully my dealer will be tuner friendly.
View 14 RepliesMy 2011 SD started clunking while in 4x4 this weekend. I was on an icy road for about 120 km driving about 60-80 kph and once or twice noticed a random clunk. Didn't think much of it.
Fast forward to following day - get truck on an icy hill where I had to make a sharp turn. Put truck in 4x4, turn off ATC by holding button 8 seconds. Only rear wheels engage. So then try 4 LO. Same thing. Straighten wheels, shift to park, engage 4x4 again and she hooks up and drives out no problem. Further down the road (still in 4x4), it fish tails slightly and then check 4x4 light comes on. In order to get 4x4 re-engaged (was spinning at a stop light on a slight incline) I had to shut truck off and restart it. Then it seemed to work normal and light went off.
Little further down the road I had to go up a steep incline and at a steady 40-50 kph I started hearing (and feeling) a noticeable clunk every few hundred feet. Seems to be coming from rear of truck but honestly cannot say for sure. Goes away when in 2wd.
I have 7000 kms left before warranty expires luckily.
2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.
I've got a 2011 F350 Lariat crew cab and when i get up to 75 mph with a cross wind, there is a whistling noise. it sounds like a turbulent whistle as if its blowing across the ribbed portion down by the wipers. I tried to get audio but for some reason my phone wont pick up the noise, but its extremely loud at times. Sometimes it will wake up the kids if they're napping in the back seat.
View 14 RepliesSo, I recently had my 4th oil change done at the dealer, just under 36k miles. Same dealer that has done /all/ service on my 2011. They used the same parts and materials as always, but this time there is a very noticeable "typewriter" sort of noise at idle. Much louder than the normal chatter, and not consistent - tick.... tick-tick... tick.... tick... tick tick tick... etc. The diesel tech shrugged it off: "Ford says it's nothing to worry about." As it has never happened before, and it sounded a /lot/ like lifter noise resulting from a low-oil condition, I asked him to put in another quart. He did, and the noise went away. Mostly.
Now I've only driven about 75 miles since the oil change, but the last time I drove it, I had the windows down and noticed what sounded like lifter noise again. Not the same pattern at idle. This time, it was under light acceleration and the frequency increased with engine speed. It's going back to the dealer in the morning. Not only for this, they're also on their third attempt in the past 2 weeks at fixing a squeak in the dash. But while it's in, I want this noise to go away.
In spite of all the posts about how this sort of noise it typical with new oil, and goes away in 10-2000 miles, I'm concerned. Nothing has changed other than the fresh oil and filter. In the last 3 oil changes, this condition never existed. Am I being reasonable?
I have a 2011 that does not currently have the complete factory exhaust system on it and no muffler. With the nice weather I have been driving around with the windows down and hear a noise out of the exhaust that sounds like tires spinning on wet pavement when I let off the throttle or at some shifts of the transmission. Boost seems normal, and don't hear any noise while under load. I think it is just the VGT closing and making the noise. With deleted sys heard this noise in exhaust?
View 4 RepliesDriving home from work (a 30 minute hwy cruise) I had to stop for a traffic light. As was sitting there I hear a thumping noise from under the hood, otherwise it was running the same as always. Got it home and I didn't hear it anymore, looked under the hood while idling, seen nothing, shut it off. top rad hose had a slight amount of pressure, started it and it quickly built pressure and felt a rhythmic thumping in hose and it got fricking hot quickly. I figure either a head gasket or cracked head.
I just recently did an aggressive cooling system flush using Prestone heavy duty cooling system flush (can only get this at a dealer) because the previous own neglected it, and it blew a head gasket, tons of rust inside when I did it. I'm gonna borrow a tester to check for exhaust gas in the cooling system and what did it end up being? The guy I bought it from (the previous owners mechanic) put 1 or 2 head gaskets on it.
heard a loud squealing noise and now no boost. 2011 with 90k miles
whats my options and what would it cost.
1. replace with factory turbo
2. replace with upgraded turbo and tune?
My buddy has a 2011 250 and is having some weird issues with a clicking noise. It started out when you put the truck in gear (D or R) and touch the gas it would click. Seems to be coming from the middle to rear part of the truck. Now it clicks when he's driving. This all started after he got 35's and a leveling kit. It's taller springs in the front and added a block in the rear. It has less than 15k on it.
View 14 RepliesWhen I start the cold engine mine makes a loud whining noise. I took it to the Ford dealer and they said that the sound is normal and that it's the turbo's. I think I'll take it to another ford dealership and get a second opinion, The service guy has the same truck as me and his was making the same noise on cold start up and they told him it was the turbo's also. Something's not right about the noise.
View 14 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?

I'm looking at maybe trading for a 2004 F350 with a studded and deleted 6.0. It has a "thumping" sound coming through the intake like an exhaust valve is staying closed. My question is, how common is it for the rocker arm retainer or rocker itself to fail? It has 204k miles, and the owner says he was on his way home about 2 weeks ago and it just started doing it.
View 3 RepliesI got a little oily residue on my hood here. It looks like it might be a little wet near the coolant hose & throttle body area. I also have the H&S Intercooler pipe kit installed. Not sure how long this residue has been there, but it is still wet, so its not all hardened. Maybe it's just loose intercooler pipe bolts?
