Ford 6.7L Power Stroke Diesel :: Engine Made A Tapping Sound For Few Seconds Then Shut Off After Loud Pop
Sep 13, 2012
The EMS service in the county next to ours lost one of it's new trucks for a few days on Tuesday. While going on a call, the engine made a tapping sound for only a few seconds, then a loud pop and shut off. Ford dealer went and picked it up and took it in for evaluation. VERDICT: Broken rod and cracked block. I have to say, this is the first I've heard of a 6.7L having a problem like this in our area.
Ford was really interested in this engine, as a new one is already on the way and the old one is to be shipped back for complete breakdown. So far, the Director and County Manager have been impressed with Ford's response to this problem. Dealer has told them the truck should be ready by the middle to end of next week. If I hear anything else, I will let you know. Any engine can break at any time, I'm just glad they are moving quickly to rectify the situation.

Not sure, it doesn't seem to me the dreaded fuel pump problem. Was driving on highway pulling my 5th wheel after going though the toll both it never went out of 3rd gear and motor started taping pretty bad, turned tow haul off and it shifted up. All along never seemed to lose power, as I was looking to pulled off high way and into A park in lot it started losing power then just shut off. All along this 2min ordeal the motor was knocking/taping. Seems to me like the motor blew.

I am lost on what I need to do with my 2005 6.0. Last summer it started giving me trouble once in a while starting. I turn the key on and wait for the wait to start light to go out. When it goes out, turn the key and it starts, most of the time. Last summer I went to start it the same way, only it cranked and did not start. I turned the key off, back on and cycled the wait to start light again and turned to the start position, it started right up. Whenever it would act up I just turn the key off then back on and it starts right up. Usually on the second try, but lately it has taken 3 or more tries. I am not finding any real pattern to when it wont start.
When it does not start I can crank on the starter until the battery dies and it wont even think about starting. Turn the key off and back on, it will start.
Another thing I have noticed, when I crank the engine I can hear a clicking from under the hood right before it starts. I think it must have something to do with the injectors. I will crank the engine a few seconds, hear the clicking then it starts. If I don't hear the clicking it will not start, so when it doesn't want to start I also do not hear the clicking sound.
The other day I started it, drove 5 or 6 blocks and shut it off. After 20 minutes or so went to leave. I had to cycle the key 4 or 5 times off and back on before it decided to start. It is getting worse, doing it more frequently, and taking several times of key off and back on to get it going. Where should I start looking to find this problem?

After I shut off my truck, about 5 to 10 seconds later it sounds like a compressor or small motor is running, and it runs for about a 50 to 60 seconds. It seems to do this even if i turn the ket on and off, sometimes. What this is.

Been noticing it more recently. After shutting truck down I would say 15-30 seconds after some type of pump or solenoid starts running and does so for another 30 seconds or so ( from the frontnofmthentruck). What this might be? Also have noticed it just once after starting I was walking around the front of the truck and heard this buzzing sound once again.

I bought a 2009 F-150 King Ranch a few months back. It has 125k miles on it and the only aftermarket thing on it is some larger tires. I love the truck but twice now (at two totally different driving instances) I have started hearing this bad sounding tap in the engine. The majority of the time it has ONLY been when I am in drive or reverse. I can especially hear it if I am going through a drive through. Anyways as I was backing into a parking space today it started making an even louder tapping sound. I recorded it and have provided the link to youtube..
It continued to make this terrible sound until I revved it slightly and then it went back to normal idle. This all started as I was in reverse backing up but this is the first time it has continued even into neutral. Really hoping for not terrible news on this. Ive read about the cam phaser issue and nothing has been done to those yet. It is the 5.4L and a 4x4. How to fix this and not have a clunker for a truck...
Here is the link to the youtube video of the truck running... it was too large to be uploaded on here : [URL] .....

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!

What could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

I have a 07 f250 6.0l and it has 112k on it, I've owned it for over 4yrs, since 45k, and no issues, but this morning I went out to start my truck didn't start, tried again and started, but the glow plug controller made a funny buzzing noise, (making that noise for a few weeks), so I went to ford and bought a new controller, so I hope that fixed that, but on my way to work I was at a traffic light and noticed that my ficmv were between 46-48.5, icp 23-24%, vgt around 68%, truck was at temp, should I start to worry about the ficm??, I have to replace my ground on driver side battery, noticed that it is corroding, gonna do that, I have 2 yellow top optima batteries about 3 yrs old....

Just noticed a sound of air sucking sound under the hood on heavy acceleration only, the harder I push the louder it gets. Either sucking or hissing sound. I feel no difference in driving. No loss of power or anything else. Just the sound of air coming out like a leaking air line. I will check later this afternoon if its affecting my turbo boost. I have 235000 klms on the clock

I am working on a 2007 F350 ambulance for a volunteer fire department. It run great, even with the key turned off sometimes. This is an intermittent problem. About every 10 times it is used the engine will not shut off when you turn the key off. The instrument cluster turns on and off as normal. The other odd part is if you leave the key in the off position when the engine does not turn off the RPM starts going up. I have not left it in off long enough to see how high it would go. It does not have a remote start and never has.

So I have a 06 f350 6.0 and this started to happen yesterday. I was driving and all my temp gauges were ok says the tuner, but I noticed when I accelerated and went above 8psi the noise got significantly louder and wouldn't go above 17psi so the cause of this sound is making lose pressure somewhere.
- I check the hot side of the inner cooler pipe and boots for cracks or tears(nothing)
- I checked the cold side and the plastic seems to be in good shape except where the flex part meets the inner cooler had some little cracks in it
- I check the Intake for cracks, didn't see any.
Noise is still there and the loss of power.....so I'm at a loss!
Cold side pipe where I taped it
Hot side boot to inner cooler no tears
No cracks in hot side pipe
Hot side on turbo
Cold side of the inner cooler

I do not think, I have seen anything about the engine shutting down descending a steep grade. first it threw the "wrench" warning and than that the engine was going on limp mode. luckily no one was on the road with me, coming or going. i pulled off on the shoulder with part of the pickup and 5er on the road. no steering or brakes used the 5er brakes to stop. turned the key off and restarted it again and no code or warnings. like nothing happened. it happened twice today between yellowstone park and great falls, mt. the second time the engine light stayed on and i had to stop and turn it off and restart it and it went away.

Is there an alert setting to signal when a regen starts? My engine stumbles badly a few seconds after a regen starts. The dealer hasn't found the problem. Right now I just keep an eye on the soot level gauge.

I just finished installing a new set of injectors, standpipes and the blue spring kit on our 2005 Excursion 6.0. The truck idles and runs much better but now it takes almost two seconds of cranking to start the engine. Cold and hot are the same and the length of time between shut down and start doesn't seem to matter either.
What to check? I am planning to check the ICP tonight when I get home. Could I have air trapped some where in the system? This is my first powerstroke so I don't know if this is a possibility.

Last week my battery light came on for the first time in years. I have a 185 amp DC Power alternator after dealing with so many bad oem ones.
Anyways, battery light came on when i pulled up to a stop sign. I proceeded to plug my sct x4 in to see what the voltage was, with the battery light it was 11.50. I shut the truck off started it back up, no light and voltage was 13.7. Went through the stop sign got into some more traffic, started to accelerate again and this is when the truck shuts off for the first time. Put it in neutral, and it started right back up.
Several days later it shut off on me two times back to back. It was a cold start, and both times the battery light was on and the truck would die within 30 seconds. Third start it kept running fine.
This past Saturday morning battery light was on, let it idle for awhile then as i tried to park it in the garage it shut off. Started it up, no light so it ran fine. Later when i started the truck it shut off again. So it has shut off on me 5 times in the last week.
Some more background on the truck:
2005, 199k miles
Well maintained (T6 every 5k, filters every 15k, etc.)
The injectors are going bad, it started running rough saturday 1/9/16, just a couple days before it started shutting off.
I used to a sct x4 to pull codes, i have p2237 (if i remember right) which is an intermittent icp signal. I replaced the pigtail and icp less than a year ago because of the same code.
And three codes for glow plug solenoid open on 5, 6, and 7.
No ipr codes

Having that flash on the dash? Truck was running fine and the buzzer when off and dash said I think -- when safe stop and shut off engine immediately. Scared the scr-p out of me so not sure if that was word for word. Jump on the binders and got it off the road and called a wrecker. Now it's at the dealer waiting for them in the morning. Checked oil and don't see any leaks. Now I have lost my confidence in the truck. 42000 miles on it.
