Ford Super Duty (1999-2016) :: 2011 F250 - Fan Is Making A Loud Sound As The Motor Is Accelerating

Picked up a new to me 2011 F250 Lariat. She had a few odds and ends to take care of, but I was ok with that. So far I fixed the reverse sensors (2 were out) creaking in the back (leaf spring bushings needed a little Lithium Grease) Squeak in the back (tailgate step needed a little greasing). Now on to my next problem!

This is my first 6.2l (first f250 in general). Truck starts up great and idles quite. Taking off driving, it sounds loud as hell under the hood. To me it sounds like the Fan is making a loud sound as the motor is accelerating. It is more noticeable when you really floor it. Prior to this I owned a 2010 F150 and I know stomping on it the motor really revs up, but this other sound to me isn't right/normal. Googling around, the closest I found to it was:

Loud "Air" Sound Upon Accelerating 2002 FORD EXPEDITION - fan clutch! - YouTube

Granted it's for an expedition, but the sound is damn near identical. Looking on youtube at 1 or 2 videos of a f250 doing a 0-60 all I heard was the sound of the motor revving, so that has me convinced the sound I'm hearing is not normal. I'm 99% convinced it has to be the fan clutch.

Ford Super Duty (1999-2016) :: 2004 F250 - Engine Noise / Right Side Cylinder Head Began Running Very Loud

To make a long story short, after replacing the timing chains, guides, and tensioners, the right side cylinder head began running very loud. Think of the usual chatter associated with these engines and multiply it. It was constant, from start up to shut down, and it increased with rpm. Thought at first it may be caused by debris in the oil clogging the lifter(s). After changing the oil multiple times along with different additives and driving roughly 600 miles, the noise persisted. Taking a look down the oil filler tube with a flashlight and with the engine running, the head looked dry. Safe to say at this point I was starving the head of oil.

Removed the valve cover. Removed the rearmost camshaft cap. Sure enough, the oil passage was completely blocked. Inspected everything and there was signs of running dry (minor discoloration, dried oil spots... but no real damage and no play anywhere. Put it all back together and the truck runs quieter than the day a bought it.

Here's the camshaft cap:

This is exactly what it looked like after removal. The material blocking the passage is hard and bridle like plastic.

Ford Super Duty (1999-2016) :: 2000 F250 - Making Ticking / Knocking Noise

I have a 2000 F250 5.4 that has a ticking/knocking noise. After about 30-60 seconds of first starting the truck in the morning, the ticking/knocking noise appears. It sounds like its coming through the exhaust system and seems to be louder under the front passenger side wheel well. When I rev the engine up, it seems to go away. Does this engine have a cam phaser? Could it be timing chain slap?

Ford Super Duty (1999-2016) :: 2004 F250 Making A Sort Of Ticking Noise

My 2004 f250 5.4 Triton has been making a sort of ticking noise, it almost sounds like my lifters have a little play in them but it also sounds like an exhaust manifold leak. They both would sound about the same and it seems to be getting a little worse of gas mileage than before. Also, the check engine light was on from Saturday into Sunday night then it shut off Sunday night and hasn't been back.

Ford Super Duty (1999-2016) :: F250 5.4L - Engine Making Puffing Sound Out Of Exhaust

Here's a link to a video where you can hear what I'm describing. The noise is most noticeable around the start (first 18 seconds) and the end of the video when I'm closest to the exhaust pipe:

YouTube ....

You may need headphones to hear it, but the engine seems to be making a bit of a puffing sound during idle. It happens completely randomly and I'm not quite sure what could be causing it.

Aside from this noise, the engine seems to idle normally, and the check engine light isn't on. I had all of the injectors out a few weeks ago for cleaning. They all appear to be working fine. I also cleaned the throttle body at that same time and ensured there were no obstructions for the air intake and filter.

What might be causing this sound? 1999 Ford F250 Super Duty 5.4L

Ford Super Duty (1999-2016) :: 2006 F250 - Intermittent Loud Chirping Noise

I have a 2006 f250 lariat 192k no mods except k&n filter everything is stock. I have 2" pro comp level kit and a scan gauge 2 nothing fancy! Well the other day I noticed my truck was chirping like a Chirp chirp chirp...... Chirp chirp...... Chirp chirp chirp! It goes up and down with the rpm's but it's comes on and off only when the engine is up to running temps the belt does squeak during warm up but I don't think that's it, it's coming from the back of the engine I'm sure of it because I used a paper towel tube and listed right in the turbo hpop area on top of the engine but it's too hard to tell I can't find exactly where it's coming from, some people I've had listen think it's a belt or pulley or tensioner! But I'm not sure if it is because I've sprayed water, and wd40 on the belt and pulleys with no change!!! I'm afraid it's a lifter or something inside the engine yet it's too loud and pronounced to sound like it's coming from the inside! I'm just lost!

Ford Super Duty (1999-2016) :: 2000 F250 - Loud Banging Noise When Going Over Bumps

I have a 2000 F250 2wd 6spd with a loud banging noise that has been vexing me for quite sometime now. The bang happens when I go over bumps (even small ones like road reflectors) while driving. I don't think it is suspension related since all the ball joints, front/rear swaybar and endlink bushings have been replaced fairly recently. All the springs and bushings also look okay.

The noise seems to come from the rear, and I notice that if I let off the gas when I go over a bump, it does not make a sound. Conversely, if I am accelerating aggressively and hit a bump, the sound is much louder. Also, if I step on the clutch while keeping my foot steady on the gas, it makes a bang. Jumping up and down in the bed while the truck is parked does not recreate the sound. I have already greased the driveshaft spline joint so I'm thinking the sound might be differential or transmission related. What it could be?

Ford Super Duty (1999-2016) :: F250 - Loud Ticking Noise For A Short Period (30 Seconds) On Cold Startup

6.2L F250 truck is just shy of 60k runs good however on cold startup there's now a pretty loud ticking noise for a short period (30 seconds) until it warms up then it slowly goes away. Once its warmed up there isn't much of anything.

Did these have exhaust manifold gasket problems like the 5.4? Hoping that's it if not, any other common problems that would make that ticking noise and then go away quickly once the engine is warmed up.

Ford Super Duty (1999-2016) :: 2004 F250 - Loud Whining Noise / White Smoke From Serpentine Belt

I bought a 2004 6.0L F-250 used a few weeks ago. There have been a few problems here and there that I have been competent enough to fix. I am now facing a problem of A: the truck not starting (I believe it was just a battery problem, charged and started fine). But also B: I have had a slightly frayed serpentine belt that I noticed a few days ago. After I got the truck running from my the no-start and driving it around the block I parked it and went inside. Came back out a few minutes later and I tried to start it. It hesitated a little bit but started with a loud whining noise and white smoke coming from the belt. Turned the engine off and saw on one of the bottom wheels (pulleys?) some residue that looked and smelled like burnt rubber. Is this just simply a need for a new belt?

Ford Super Duty (1999-2016) :: 2012 F250 - Starter Spins / Spools Up Very High And Loud But Not Crank The Engine

Starting about 4 months ago, when starting my truck, the starter would miss; I would turn the key to start, then the starter spins and spools up very high and loud but not crank the engine. I have to turn the key off to make it stop and then try again. Usually the second or third time it will grab and turn the engine and start. It happens about once a week or once every 10 or 12 times I start my truck with all the other times being normal. Doesn't matter if it's a cold start or already warmed up. It's a 2012, 6.7L F250 with 52,000 miles. What is causing it and how it can be fixed.

Ford Super Duty (1999-2016) :: 2000 F250 - Front Suspension Noise - Loud Knock As If Left Shock Is Bottoming Out

I have a noise with my new (2.6k miles) 2000 Diesel F250 Crew Cab. When I make low speed, right turns while crossing any type of depression in the road I hear a loud knock as if the left shock is bottoming out. There's an intersection near my house with runoff depressions across the road, I almost always hear the noise when making that turn. I've occasionally heard it coming from the right side when making a left turn.

Ford Super Duty (1999-2016) :: Fan Is Loud - Noise Is Related To Engine RPMs

I have a 2004 PSD with 85k miles. The engine fan is all of a sudden loud. You can clearly hear the fan pushing air and it's noise is relative to the engine RPM. I've had this truck since it was brand new and have never heard the fan blades unless I had my head in the engine compartment. Is the fan supposed to turn relative to the engine RPM or is there something wrong? Either way it's now all of a sudden super loud.

Ford Super Duty (1999-2016) :: 2004 F250 - Humming Noise From Engine At Idle

I have a 2004 ford f250 5.4 and ithe makes a Humming noise only at idle. I have checked the fan clutch. it seems to be good and does not spin freely. I was thinking maybe idle air control valve but the truck idles like normal and does not stall. the sound does go away when squeezing the air hose doing today the IAC but comes back as soon as you let off. can it still be the idle air control valve if idles fine and doesn't stall?

Ford Super Duty (1999-2016) :: 2006 F250 ZF6 V10 Making Faint Grinding Noises

Went on a 400 mile trip today and noticed some strange noises. The rig is an 06 F250 lariat, V10, Zf6, SC, LB and only has 43k miles. It behaves normally except when coasting down a hill at 65+ mph, and it doesn't matter if I'm in neutral or overdrive, it makes a feint grinding sound that gets louder as speed increases. Maybe grinding isn't the best word to describe it, I'd say a cross between humming and light grinding. As soon as I give it any throttle or put any load on the tranny is goes away. It's really freaking me out as I just got the truck a month ago and I know the ZF6's are almost bulletproof.

Ford Super Duty (1999-2016) :: 2006 F250 V8 - Knocking Noise In Engine And Oil Pressure Drops

While driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.

Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.

Ford Super Duty (1999-2016) :: 2000 F250 V10 - 4R100 Making Noises Audible While Driving Especially In Third And OD

Troubleshooting on my wonderful transmission. I have a 2000 F-250 CC Lariat with the V-10. When I start the truck, I hear a high pitch noise. It's like a high pitch whine. It changes frequency as you rev the engine in park. Put the transmission into gear. Either forward or reverse, and the noise is lower pitch. As you accelerate, the noise will change frequency. If the tranny is manually shifted, the noise will go away, and then come back a short time later. The noise is audible while driving especially in third and OD. The truck has 93,000 and is dead reliable except for this. I have been under the truck, and I can tell it's coming from the tranny. Not sure if it's the converter or what.
