My squeal is only present at my tail pipe at rear of truck its a 2007 f350 straight pipe . 6.0 engine. 300'000 miles . just bought this truck . believe turbo has been replaced but not sure as to when. This noise is very loud ear splitting at an idle. Builds boost just fine. No noise at turbo area other than the normal slight whine.
View 6 RepliesYesterday 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.
View 9 RepliesOn 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.
View 9 RepliesI noticed a rough idle after driving an hour with a 6000 lb trailer and stopped at an offramp. Had no performance issues to that point in an hour drive. Then I noticed a good amount of white smoke coming out of the exhaust. The idle felt just like when I had a contribution/balance code on #5 a year ago, and a new injector fixed that. Before long (10-20 minutes later) the idle got real loud, like a big knock/loud tick every revolution.
I had a bunch of stored codes, so I reset them and later found a P0281 - Cylinder 7 contribution/Balance and P0404 - EGR control circuit range/performance were the 2 that came back. I drove it 2 more hours to get home. It ran well under load, but coasting or stopped gave the loud knock, and stopped and idling was a rough, inconsistent idle. It even stalled on me 3 times when braking for a red light (auto trans). There was a lot of white smoke all the time, plus a little dark smoke on acceleration.
What would you recommend for troubleshooting steps? I could put a new injector in #7 and clean the EGR valve, but want to have a good idea that will fix it first. Is there a good chance I have a messed up piston in #7 now?
Codes I cleared:
P0148 Fuel delivery error
P0234 turbo overboost (i know i need to pull and clean the turbo anyway, unrelated to today's issue)
P0281 Cylinder 7 contribution/Balance
P0404 EGR control circuit range/performance
P0670 Glow plug (I had the module unplugged a while ago)
P0683 Glow plug (I had the module unplugged a while ago)
I have a 2013 F250 6.7 w/ 96000. I ran over a log and tore the rear section of the exhaust. I was told to buy the OEM version or do the DPF/EGR Delete.
I don't have a lot of $$$$, so which way do I go. Whats the least expensive Delete.
Just over 7000 miles all of a sudden I got this loud grinding noise in the rear end like a brake locked up. Pulled into a parking lot. Don't think it's brakes. Put the truck in reverse it got even louder for a second then it quieted down after that. Naturally this happened on a Saturday.
View 6 RepliesWell I'm am getting a low toned squeal out of the left front of my truck every time I pull away in the morning. I thought it was the caliper sticking as it wasn't releasing but I replaced the brakes and that and it still is happening. I guess I am going to looking at the hub and see if the hearing is bad. What do you all recommend for a hub replacement. (OEM, moog?) I looked it up on white bear is part # AC3Z-1104-B right?
View 2 RepliesExperiencing a squeal under hard acceleration at 3000 rpm with roughly 20lbs of boost, not present before and not present after 3000 rpm. light acceleration to 3000 rpm does not create sound, as well as turning 20lbs at a lower rpm (higher gear with throttle input). Truck has an EGR delete, EGR delete up pipe. EGR valve is still in place and plugged in. Truck did come with a banks six gun, so does not have EGR delete tune, however no trouble codes are present. What to check?
View 9 RepliesI have a 2006 350. When I am pulling my camp trailer (about 12,500 lbs) up a grade I hear a fan or blower turn on and I get a high pitched squeal. It will also have a beep and my in dash display will say high engine temp. I have a bullydog pmt programmer (i tow with it in stock mode) the display will show my coolant temp at about 180 degrees. If I pull over and let it idle for about 2 minutes the warning clears and the temp gauge returns to normal. the display reads about 180 degrees the whole time this goes on. I know the engine is not over heating so why do i get this warning and squeal?
View 4 RepliesAre they known to cause any noise? VGT Solenoid.
I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.
It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...
I've topped up the DEF and the warning is still showing that I'll have reduced engine power within 45kms.
Its weird, just yesterday it showed 550kms to empty so I added one full container, all day it kept showing less and less kms' til empty. Warning lights and bells etc.
This evening topped it completely and still shows. Is there a way to reset it without having to stop at the service dept.

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.
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.....
Say I just purchased an 06 f250 crew cab with the 6.0.
I had her trailered home due to dead batteries. I got her started up and drove about 5 miles until she got up to operating temp.
When I came to a stop and tried to accelerate, she immediately bogged down and started studdering with white smoke coming from the exhaust.
I shut her down and started her up again. She started and idled fine, but as soon as I pressed on the accelerator, she bogged and studdered again. I shut it down again and started it back up. Normal idle, and I shifted her into gear and was able to mozy on idling forward without having her bog, but as soon as I touch the accelerator, she bogs and studders.
I towed it home and the next day (today) she started just fine and I shifted her into drive and moved it forward about 10 feet. Did not touch the accelerator so she didn't big or studder.
1. I am guessing the white smoke was coolant burning through a failed EGR circuit. Do you seasoned members agree?
2. It the a check engine code when studdering. I have yet to check codes so I am still in diagnosis mode.
3. I plan to block off the EGR pipe and throw in a new oil cooler. Anything else immediate I should be considering??
So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
I have an exhaust smell in the cab of the truck. It is pretty strong. Seems worse when it is really cold outside and goes away when outside temps warm up. I checked the tube (passenger side behind engine) and did not see any soot.
View 12 RepliesWas cold this morning, -15c, and I remote started the truck and then left home about 5min later. I could smell exhaust in the cab. I read some of the other threads about this. How can I tell if it was doing a regen? I have an Edge Insight. Is the a parameter I can display to know the regen was active?
View 14 RepliesLooking for if it would be okay to tune my 6.0 with the SCT SF3 tuner with the stock exhaust, I measured it and the stock exhaust is 3 and 5/8 inches...
View 5 Repliesyesterday I went out started my truck and white smoke started coming out my exhaust so I turned it off waited a bit started it back up let it run for a bit smoke went away drove it about 60 miles. Later that night it did the same thing but I was 2 gallons short on coolant drove it another 60 miles ran fine. Next morning decided to take it to a shop put more coolant in it drove maybe 20 miles to shop got there turned it off everything was fine never over heated once. So this shop is now telling me my trucks hydro locked and I steamed the EGR valve. And there telling me it's gonna be $8000 to fix it .
View 3 RepliesLast winter I pulled something and getting out has been difficult. Climbing in my F 350 even tougher so it hasn't been used much. Now that I'm driving a bit I have not seen it regen. Truck stop regenning, is it possible? What happens if it just stops? It use to regen every 200 miles or so and I have been paying attention.
View 7 RepliesI'm at 76K miles and I had another exhaust sensor go bad. This time the check engine light came on and the truck did not shut down. I was prepared this time and had an extra sensor / code reader handy.
It was the last sensor in line and very easy to get to. It took me less than five minutes to complete the job. I did use anti seize, but as easy as it came out it probably wasn't necessary.
