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.

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.
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?
View 8 RepliesI am getting ready to go on vacation this weekend with my f350 and I was driving today when suddenly the truck shut down while going at about 25 mph. I tried to start it and it just kept cranking. I got it started 5 mins later and it threw a P0069 code. I drove for about 2 more miles and it shut down again, and started right back up. I'm guessing map sensor? This was the last thing I needed to happen!
View 14 RepliesSo I am out of town about 120 miles from home on a job. I was driving down the mountain road to the store and my tuck just shut down. Lucky for me I was able to get into a turn out. So I try to start the truck and it will not fire. I check for codes I am getting p2614, p2617 so I was able to clear the codes and get back to the house I am staying in. What is going on with my tuck. Oh ya the code did not come back on in the 15 min drive to the house. Also just finished up doing a y pipe and my egr o ring so I and the intake and all that off.
View 4 RepliesThe 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??
Just got this injectors done. Filled the tank up. Drove for 1/4 of a tank. Went to leave out yesterday. Made it out of my subdivision and down the road 3 miles or so. I was going 55 when the truck stalled. I tried to start the ignition it would turn over, but wouldn't catch to stay running. I did this at least 8 times. Friend came with Ether. Tried 3 separate times, truck started going dead. So i was about to give up... Tried it 1 last time, it fired up like a champ!
View 6 RepliesSo a few day ago my truck shut down while driving. I posted up and checked the ficm harness as suggested. Things were a bit lose so I zip tied my harness around the ficm. Thought it was all fixed and test drove it and it shut down again. I tried to start it a few times and my ICP was a tad low about 450 ,I have a brand new ICP and harness. Checked my scan gauge and I have code p2614. I cleared the codes and the truck started right up. I need to get this sorted out I was supposed bro go home tomorrow from working out of town all week about 100 miles from home...
View 3 RepliesJust 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
View 5 RepliesJust pu my new 2013 6.7 Diesel with 1300 miles... There is a most annoying whining coming from under the hood and sound like its coming from the secondary filter area or turbo (you can even feel it if you put your hand on the filter lines and housing) and it starts a minute or so after the vehicle has been running and you can her in the cab at 70-mph... At drive through restaurants I have to shut the tk down to place my order and never goes away..

I have a 2003 F350 with a 6.0. I just finished replacing my HPOP (Adrenaline Pump from Diesel Site) and fired the truck up and its making a hissing sound from the rear of the motor back by the turbo almost sounds like a tire leaking and its loud enough to hear over the engine. The truck is running and idling good but it doesn't seem to be quite 100% when I step on it.
View 10 RepliesI noticed when I shut off the truck about 30-40 minutes later I'll open the degas bottle cap and notice there is no pressure.
I used a coolant pressure tester kit and pumped in 16PSI but couldn't hear or find the leak.
I'm going to buy a smoke machine in a month or two but until then, can I still drive the truck ?
I'm guessing it is a pin hole leak somewhere as once I shut the truck off... there is a lot of coolant pressure.
Okay so 2007 F350 DWR here, I have a driver who hauls loads using the truck and a 25' gooseneck trailer. She's gone through the bullet proofing process at 80K miles, she now has 128K miles. I have a programmer to monitor temps, and do all required maintenance.
With that said, my driver reported last week that when under load and going up hills he got the white spray coming out from under the hood. See pics below, this is never really good of course but I want to believe its not catastrophic. Two weeks prior I changed out the thermostat and upper radiator hose and of course flushed and filled coolant, all was good - no hoses were loose, etc. Driver reports the truck did not overheat at any time.
Both ECT and EOT are within 10-12 degrees of each other, and did not go over 190 for me while driving around town the other day. There are no codes present, I cleaned the engine bay and drove and re-inspected but can't tell where the coolant is coming from as none appears to be leaking. Last note, I have to admit after driving for a day or two I had to fill the degas bottle up about 3/4 gallon of water. My questions is, what is the next step for me in the diagnostic process?
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.
View 6 Repliesgot in the car this morning, it revved a little high and now sounds like an air pump is constantly going. You don't hear it as much when you drive but when stopped and especially when you open the hood, its like a compressor is going. It seems to be coming from the back end of the air intake tubing...on the passenger side, not near the intake itself.

So my '01 E350 has been fine but tonight when I went to start it I didn't get a WTS light and the SES light was on and there was a weird number on my PHP Hydra that looked like r5 ? This happened a few times back to back so I tried starting it and it just cranked and cranked. Wtf? So I started pushing the button on the chip and all of the sudden I got the WTS light and the hydra flashed, now the chip was on tune 10 instead of 5 where it was when I parked it. I should also note that during these episodes there was a fairly loud clicking/clunking sound coming from the drivers front under the hood when I toggle the key on.. Sounds like maybe a relay? Louder than I recall ever hearing.
View 5 RepliesI have had my truck for about 4 years bought it used. I've replaced the motor due to #1 cylinder blowing up. So after I replaced the motor, it wouldn't start. Replaced O rings on HPOP (High Pressure Oil Pump) and started. When moving back to Colorado where I am stationed. It started getting harder and harder to start.
Then it got to the point where it wouldn't start so I would have to wait until I could start it or use a shot of starting fluid and yes I hate that. But I don't have a choice. I've bought new O rings replaced them and my IPR with upgraded screen. It fixed it for a week then the hard start came back. Tried unplugging ICP Sensor still hard start problem. ICP was reading 85%. When the truck is cold it fires right up no problems till it gets hot! Then driving down the high and hitting an off ramp it will shut off. When I try revers it will also shut off. The truck only has 111,252 miles.
If it can go wrong, it seems like it does.... Washer fluid is not pumping. The other day I am almost sure I heard the pump running but no fluid came out. Yesterday I filled the reservoir and now I don't even hear the pump. It's been very cold so I thought maybe the fluid had frozen? I can't find the fuse listed for the washer fluid pump and was going to check that first. Where is the pump even located? 2006 F350
View 6 RepliesThe 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.
My engine cooling fan came on when I first started the truck, was reading of 2k on torque app, ECT was appx 100* with the EOT a little cooler after about 5-10 minutes things went to normal around 600 rpm. It did not happen anymore during the drive, I was seeing about 192* ECT and 198-200 EOT. I let her set for 2 days and took her to town and the fan was at normal RPM's, Is there any problems or is that normal?
View 9 Replies6.0L Forum - I've noticed an unusual sound on my truck. Upon driving if I make a turn more than 15 degrees a "rubbing" sound can be heard through the turn, no "knocking" is not present. Once the steering wheel is straight the sound changes to a "whir". If I turn less than 15 degrees a noticeable sound can not be heard. As the RPM's vary, the sound will also vary. If I get out of the truck and listen for this sound in the engine bay I can not hear it. The sound is only distinct within the cab. It sounds like a weak motor trying to move something or a pump running low, my guess in the dark.
I've checked the oil level - good
I've checked the transmission fluid level - good
I've checked the power steering fluid level - good
I've checked the brake fluid - good
I have read that a master cylinder could wear and create a rubbing/unusual sound. What else should I check for? The truck has 238,000 miles.
