Ford 6.0L Power Stroke Diesel :: High Pitch Whistle Noise From Turbo / Exhaust Area
Apr 27, 2015
For a while now, I have been hearing a very high pitch whistle noise from the turbo/exhaust area. Everybody told me it was an exhaust leak, but I never could pin point the leak. While I was under the truck last weekend I found the flex joint on the passenger side up pipe was broken a leaking.
I ordered a Dorman replacement pipe that comes with a new gasket and hardware.
I will be the first to admit, I am not a fan of Dorman parts... BUT, this pipe is really nice. It looks identical to the pipe being sold on Dieselsite.com, it doesn't have the scoop inside to direct exhaust gas to the EGR cooler and it comes with all the mounting hardware.

Once I got the turbo down pipe out of the way and soaked the bolts with penetrating oil, I had the broken up pipe off in 30 minutes.

For a month or two now my truck has been making a squeal and the turbo has been sticking after hard acceleration. The sticking was a woebegone unison ring and I was hoping the squeal would be resolved when I cleaned the turbo but it didn't, in fact, it got worse.
It used to be occasionally and go away after warming up, but now it's more constant than not. It goes away when the VGT does its idle cycle and once you get up to speed.
Here's the sound - YouTube.....

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?

Your breaks yet? Mine are starting to get really annoying, that high pitch noise at slow speeds with just a slight touch on the break peddle. To give an idea of loud, I have hearing loss from my job in the military and they are starting to bother me.

Had a bad turbo on my 07 F550 with a 6.0. Replaced it today and took her for a ride. Started smoking and oil was spitting out of the weep hole in the muffler. A lot of smoke. The truck was smoking before I replaced the turbo too but I didn't have any oil coming out of the weep hole. I'm hoping it is just oil that had been passed into the exhaust by the bad turbo that is now being burnt off and pushed out by the new turbo. Does this sound plausible?

Yesterday my truck started making a loud high pitch squeal at idle. Messing with it this morning I found when I turn the a/c on it quits. Then it will do it for a second at startup and quit. If the a/c system is turned off it comes back. I thought exhaust leak until I found the a/c link.

I have 07 F350 6.0 never heard this out of any of my 6.0s. it's almost a whine but can hear it w turbo and out of empty exhaust. Almost like a supercharger noise stumped almost leaning towards actuator for turbo? Noise got real loud swapped turbos used same actuator noise is there but much quieter.

Stuck turbo and high deltas so I replaced the oil cooler, coolant, thermostat, rebuilt turbo. Etc etc. Now I'm getting p2284/p2285 intermittently. Upon inspection ICP looks great at idle and 2500. IPR at hot idle is 20.9 but when you run it up to 2500, it drops to 14.7 and after a few seconds hpop at idle jumps to 875 and I get the p2284/2285. Bad IPR?

So I just purchased my first diesel a couple weeks ago (2003 f250 Lariat). I love it! However, I'm having concerns about my turbo whistle on it. At idle and while in higher RPMs is sounds ridiculously loud (even at 0 PSI in the boost). I've been doing my research on it and I know the 03's have the loudest sounding turbos because they have less vanes than the later models. I know without a video it's going to be hard to diagnose, but I am wondering if a loose boot would cause a turbo whining sound through the exhaust? I have yet to hear ANY other diesel in person that has a turbo whine as loud as mine.

I have a 01 7.3 F-350, 120000. I rarely get down hard on the go pedal but a while back I did and heard at pressure whistle just before it would shift. I thought a bad turbo hose so I replaced them all. 'While working on the hose mounts I cleaned up the castings for a better seal'. The hose replacement seemed to get the running but the whistle is still there. I am thinking a leak on the manifolds for the Y-Pipe connection OR does the turbo have a release valve that can make a whistle sound?

My girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.

In addition to significantly louder noise from the Turbo on start-up, we've started to hear a pretty concerning noise while descending a hill in Tow-Haul. Not sure that the T/H has anything to do with it other than getting the engine in a RPM range that causes the noise. We've taken it in and tech says "That's just normal noise"... What ever that is.
Here is a link to an example : Tow haul making a lot of noise in my F350 diesel. Pulling a very heavy horse trailer. - YouTube

I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

I've been noticing some new noises in my Elantra in the last couple of months.
First, there's a clunking noise that sounds like it's coming from the steering area. It usually happens when I back up and rotate the steering wheel, like when I back out of my parking spot. More often it's in the morning.
Second, when I turn the fan on there is a high pitched squeal. If you turn the fan off you can hear the squeal more clearly for a moment as the fans die down. This one only started happening in the last couple of weeks.
I guess I'll have to take it in and get them to take a look. Last year it was a squeaking in the pano roof which only happened when it was hot out. They seemed to have lessened it but it wasn't gone completely.

I have a 2009 Tiguan 2.0t 4 motion and recently has started having a very high pitched squealing noise coming from either the accessory belt area or the timing chain. The noise is constant until you are under acceleration and then it goes away. The CEL came on but when scanned it said no codes. and now sometimes the CEL will flash and the car has been idling rough. What it may be?

I have a 2005 F250 with 186K miles. I do minor work on my vehicles but have little experience working on my diesel. I was accelerating when I heard a pop and a hiss similar to disconnecting an air hose from an air compressor. Total loss of turbo power. No turbo reading on the turbo gauge on dash. No loss of oil. No smoke. Oil and coolant look fine. Took off turbo and everything appeared to operate like it should (according to YouTube videos). Inspected lines and rubber boots.
Rubber has some cracks but not certain if they are holes. How small/large of a hole would cause total loss? Was originally scared to take it to a shop knowing they could name their price. Not opposed to taking it somewhere now knowing the turbo works but obviously would rather save the money. Any tips on troubleshooting? I'm not opposed to proactively replacing parts/sensors as the truck has given me 186k and I plan to keep it as long as possible.

My truck's been doing this ever since I got it when the engine is cold. Haven't brought it up to a dealer yet because I'm not sure it's a real problem, and since it only does it when it's cold I'd have to leave it overnight.
It seems to happen when the turbo hits a certain RPM. I got it on video but you can't really hear it until the end when I raise the RPMs a bit.

My 2007 Prius Touring creates high pitch Squeak/Whistle sound while accelerating and braking, But if I put the car on neutral then the sound completely goes away. I have all the holes covered on the both side mirrors and this still occurs. The sound is constant for as long as I accelerate and Brake and the intensity varies with how hard I accelerate or brake, It also does that during regen braking when I leave the accelerator.

After towing my jeep 4 hours round trip for an offroading day, I noticed a jingling/rattling noise from my grille area. It is less audible from above (hood open), to my surprise. Everything works fine still, including the fan kicking on while pulling a hill as expected.
The only related thing I can think of is that I changed my belt before this trip because the old one squealed when it accelerated the fan and when it held full speed (2000+rpm fan speed). The new gatorback belt did not squeal at all. Could I have hurt the tensioner by pulling the belt too hard to remove it? I used the method of pulling the belt up on the passenger side of the alternator to get it off, and to put the new one on.
I notice the belt tensioner moves a bit at probably 20-30 hz, kinda dancing around. I don't know if it did that before.

So my understanding is that if your turbo is leaking oil, you either need to rebuild it or get a new turbo cause the one you have is shot.
I have some oil leaking, but it's not a ton. One one of my buddies was telling me that it's possible that the amount that is leaking is normal due to the PCV (Pressure Control Valve) system, or something like that. Here are a few shots of the turbo, as well as the boots that are leading up to the turbo.
