Ford 6.7L Power Stroke Diesel :: 2011 - Turbo Noise At Exhaust
May 21, 2017
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?

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.

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?

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.

Just wondering, what the max boost rating on a stock turbo, stock engine in a 2011 is. I know the gauge goes up to 40 PSI, but I don't think I've ever seen my go past 20.

Bad day for the 2011 yesterday. Pulling my TT home from a great weekend tailgate. Stopped at rest area for a bio break. While accelerating on the on-ramp back to highway speeds, I hear/feel a pop under the hood. Immediately pulled over, and did a quick visual inspection, didn't see anything obvious, nor was anything dripping. Proceeded back onto highway.
Torque Pro indicated a P0471 & P1247, however no CEL lit on the dash. Noticed turbo boost was zero/near zero, and power output was way down. All 4 EGT sensors indicating 1000-1200 degree temps the entire time. Was able to make it home at reduced speeds. Noticed an odor burning engine oil too.
Was afraid truck wouldn't restart, so took it directly to the dealer after dropping trailer at home. Seems as though this should be covered under the 100K engine warranty, and I am at 95K now, so the timing was good if it was going to happen.

I have a 2011 f-450 6.7 - truck has 70K miles. The other day I was driving and the message said "Cleaning exhaust filter ". I usually keep it running a little to finish. Then shorty after a warning message came on which said "800 Miles to Exhaust fluid empty". So I went to fill tank and it was FULL. Now the warning keeps showing up each time I start the engine. It now says 300 miles to empty. I'm afraid it's going to go into limp mode even though the exhaust fluid tank is full.

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
Best next steps for a 64,000 mile 2012?

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 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.

I 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

I've been mulling over the idea of doing a muffler job on my 2002 f350 7.3 cc short bed. I do tow on and off for work and dual material for work. I am thinking of upgrading the exhaust because I noticed a couple small leaks in the muffler and I'd like to lower the egt's for the truck so it breath a bit smoother. I'm not a fan of the really high pitched sounds I've heard on some I want it deep and heavy sounding. The turbo is fine for now but eventually I'll need to know what to upgrade to once it starts to wear out. I don't plan on doing dumb chips or tunes because it's not a toy truck but a work and daily driver.

On my way home from picking up or new Voltage 5er, I could hear a loud squealing noise when we pulled up to the house. After crawling around the under side of the truck I found the last exhaust thermal couple had either blew out or just fell out.

So, I just got my turbo back from my pal Ruben at SoCal Porting (does good work fast and inexpensive) and, I have a question about the exhaust housing with the EBPV.
Is there a gasket that goes between the turbine housing and the adapter that the down pipe mounts to? And, if so, what is the part number for it? If it's steel to steel cool. If not, I'd prefer to put the OEM gasket in there versus permatex or something similar.

I just got a 5 inch turbo back Magnaflow stainless exhaust system installed on my 2007 F 450. The downpipe rests directly on the firewall and causes a horrible vibration and noise at times. I have been on the phone talking directly with Magnaflow trying to resolve this issue

My 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.

My 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.
