Ford 6.7L Power Stroke Diesel :: Strange Noise After Shutdown Coming From Top Front Of Motor
Apr 13, 2011
The truck always made a few strange noises after shutdown, but this is new and annoying.
Here's the scenario: Truck is warm and no CEL. A few seconds after shutdown, I hear all the normal(?) noises and then a noise that sounds like a vacume pump running starts and continues for about 20 to 30 seconds. Cycling the key, but not starting the motor will cause the noise to happen again and again on each key on/off cycle.
The noise seems to be coming from the top front of the motor. Could this be fuel pressure bleeding off? Is there a check valve that is maybe not doing it's job??

Coming home from a trip with my truck pulling the 5th wheel, we heard noises that seemed to be coming from the front hubs that sounded like stones in the hub caps. Once we got home I pulled the front lug covers to see if any came loose and were rattling around inside, but all were torgued properly. Everything drove strait and tight with no noticeable problems, should I be concerned....

I have a 2011 f250 6.7, I park under my house everyday, so I am used to weird noises coming from my truck when I shut it off, but now that I just did a dpf and egr delete, and tuner, I noticed that my tuner doesn't shut down until the noise under the hood stops, which takes a few minutes to stop, I use to hear the air valve on the egr cooler shut when every got quiet, but I don't remember it lasting this long, any one else have a H&S mini max and it doesn't shut down right away? the place where I bought my mini maxx said it should shut down as soon as your head lights go out, but that's not the case, the headlights go out long before this noise stops and the tuner powers off

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.

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.

Got home from work this morning and noticed when I pulled in the drive and opened the door a ticking noise coming from under truck. Finally had time this evening to crawl under truck and investigate noise. It's coming from the front of the transmission where it bolts up to engine. It's a pretty much steady tick and goes away for a few seconds here and there. when you increase RPM's it's still there and I think goes away at higher RPM's, it doesn't get louder as you increase RPM's just stays the same level. Will get it to shop Monday hopefully and get this checked out and NoX sensor changed out too.

A while back I posted a thread trying to fix a clicking noise coming from the front end on my F-350 dually when applying the brakes at slow speeds (under 15 mph).
While returning from our camping trip last week the noise is back again. It does not occur after the truck sits overnight or for a few hours. But after driving for 30 minutes or longer the clicking will return when I apply the brakes at slow speeds. I tested the rotor temps with a heat gun and it seems to start when the rotor temps get above 120 degrees F. So I removed the brake pads & calipers, regreased the slide pins, cleaned up the pads and applied some lubricant on the back of the pads. I also bent the pad clips so they would fit snugger/tighter in the slots.
Whatever I did seemed to cure the clicking while driving around this weekend. I made sure I got the front brakes nice and warm - up to 180 degrees or so.
When I did this same procedure a few months ago the clicking went away - but eventually returned.
Should I get some better clips? Replace the sliding pins? Pads? The rotors & pads were replaced this winter & the shop said they and the labor are still under warranty. But if they use the same clips - I'm concerned I'll be back to square one in a month or so.

Well hear I am again fix one problem now I got another problem last time it was fuel now it's oil so what I got going on is a oil leak that looks like it's coming from on top the motor on the back I first discovered this nice surprise when I went into the store and came back out and seen two 8 inch round puddles of oil laying on both sides of the motor like I said at the back I thought rear main seal but upon further inspection it's coming from somewhere on top and rolling down both sides of the motor looks like near the turbo what could this be possibly a line or a check valve or seal or o ring on the turbo? Is there a common thing to go bad on these trucks to cause a leak in that area?

One of the many things that impresses me about the 6.7 is how well it lugs...... it'll run right down to near 1,000 rpm in 6th gear and stay there till it absolutely has to shift. Like a diesel should. Well, recently, and now more frequently my truck is making some strange noises when it lugs down. It'll mainly do it if I'm towing light, like my flat trailer empty, or maybe if I have a decent load in the bed. But occasionally it'll do it empty. As soon as it lugs down low to 1,000-1,200 and pulls there for a few seconds you'll hear a couple squeaks, then a kinda chugchugchugchug noise. It immediately quits if you let off or make it shift down. It sounds like a turbo-related noise, but I don't really know. Truck only has 9k miles on it. I just know this is one of those things I'll take it back to the dealer and they'll give me the ol "we can't duplicate the problem here." What it could be?

Fixing issues with my truck. I just ordered some latex surgical tubing and am getting ready to fix the rattling noise in my rear door by using the Epic's Door Seal Mod. Hopefully this will take care of that issue.
One more annoying noise though. Has there been any fixes to the buzzing window noise that is coming from the front passenger side. If the wind is blowing right and I'm running over 50mph, at times get a loud buzzing noise and really bugs me. Something is vibrating and at first i thought i had a speaker going out but found out that wasn't it.
I've called my dealer and informed them of this and asked if they've heard of this but of course they haven't and this usually means the won't do anything besides look for recalls or something. I have the noise recorded and scheduled an appointment with my Ford Dealer but again, they won't do anything most likely.

Nothing to be alarmed about, I'm just letting y'all know I have a coolant leak on the front of the motor. It leaks about 8oz. Of fluid/week.
I have been through the radiator issues, 5 in all on my '08 and 1 on my '11 at 52,000 miles. This one is different, I'm pretty sure it's the water pump.
I'll give the official word as soon as I can get it diagnosed. I guess it's because I tow all the time, nothing real heavy, just everyday use. Truck is hardly ever on its own.

Truck was running fine. Stopped and got fuel. Then crank truck and after about 15 secs it shut itself off. Now it WILL turn over but it is very slow and sounds "tight". 2004 f350 6.0 4x4 auto. I'm leaning towards torque converter.

My 2011 is making a strange humming sound after shutdown. It seems to be related to the normal waste gate sound. I have a video....

I have a 2012 with 41k miles on it. I noticed it was leaking oil from the front of the motor. So...I checked the oil and found it to be over full. Assuming I overfilled when I changed the oil (2000 miles ago) I changed the oil again and made certain it was filled properly, 13 qts right in the middle of the dip stick. The oil leak stops. 1000 miles later the oil leak starts again. Too much oil again and the coolant is mysteriously low!!! The dealer can get me in two weeks from now.
Time to get the 7.3 back on the road, I knew I kept the old girl for a reason. 262k of miles no truck should endure and still going strong. I was 21 when I bought the 7.3 (16 years ago) and beat the crap out of it. This truck has been pampered compared to my past trucks. I was hoping to get 14 years out of this truck too.
Is the motor OK after having coolant sloshing around in there? I just hope ford stands behind this one. I have a feeling it's not an easy fix. I am sure glad I left everything stock.

13 qts Rotella 15-40 & ford filter. I filled the filter with 1 qt before installation.
Now I have a lower motor tap, taptap or chick, chickchick. Is the oil too thick on a new motor, 5,000 miles.

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.

I have a pretty good leak coming from the front of the rear diff. is this a common problem on the 10.5 ? How hard are these to do without a lift? I still have warranty left but will have to swap out exhaust so its almost a toss up whether I do the seal myself. Also was considering a new posi unit because seems like the original is about toast, might be a good excuse to swap a new one in. 2009 with 95,000 on it. Bought it a year ago with 70,000 on it, the rear was dry till at least 90,000. I serviced the fluid at about 90,000 and didn't have a leak so now a couple thousand miles and its gushing???????

Have a 1998 F-150....heard a strange noise coming from the front passenger side of the truck. Parked and turned the wheel and heard something fall off. It appears to be a shield of some sort.

First bit of cold weather and I'm getting thirty seconds of loud clicking (or clacking) coming from the immediate vicinity of the blower motor on start up and shut down. Doesn't matter whether my climate control is on or off, it still makes the noise. I'm assuming it's stripped out teeth on one of the blend door actuator gears and I'll probably just end up replacing it. My problem: Where exactly is the offending actuator? I've removed the glove box and noted one located on the left side. I unplugged this but am still getting the ratcheting sound so it obviously isn't the culprit. I had this happen a few years back (same time of year) and out of ignorance and frustration solved it with a well aimed kick but the way it's acting this time I don't think I've got a big enough boot.
