Ford 6.0L Power Stroke Diesel :: Lack Of Boost And Air Escaping Sound
Aug 7, 2016
Well, since I replaced the MAP hose a few weeks ago the old girl has been running fine. Until yesterday. I was leaving work and she had low boost, less than 10PSI, and as I passed by a parked tractor trailer I could hear the sound of high pressure air escaping because I had my window rolled down.
So today I checked it out. I found three possible leaks spots, BUT no "smoking gun". Take a look at the pics. The damage you are seeing is on the outside of the hot side boot at the turbo and the bottom of the cold side CAC tube. The cracks don't appear to penetrate to the inside. Could these still be possible leak sites? IDK.
I'm going to order replacements anyway. Ford wants WAY to much for these parts. I checked the MAP hose and it is just like new from several weeks ago. Also, I inspected the inter-cooler as best that I can without removing it. I don't see any issues with the tanks or the tank-to-core mounting. It all looks normal. If it does fail where does it normally fail at?

I've been having issue with my truck lacking boost over the past month or so. The psi levels are normal in the morning when I start it up cold, the problem almost always occurs at start-up when the truck is somewhat warm and has been sitting for an hour or more after use. I've had boost levels at idle from -0.14psi to -0.56psi and as low as -1.2psi when driving as the problem is occurring, but it eventually kicks on and goes to normal levels after several minutes of driving. After originally taking the truck to a local diesel mechanic I was told it had EGR codes and they recommended installing an SCT tuner and cleaning the EGR valve to solve the problem. I had them install an SCT 5015 tuner and clean the valve but I've still been having the problems with boost.

I was driving and my truck started have lack of power, could barely get going on hills, tons of blue smoke (smelled like diesel) real rough idle. I unplugged injectors and found #5 made no difference. I replaced it today and I can't get it to start. It'll get to 2000+ psi 48v ficm, low pressure oil registers, ficm says its in sync. It will crank and blow a lot of black like its half firing or something. It has even crank to, until it tries to fire. From what I've been reading could it be the ficm? That one circuit is fried?

I have a 2003 with 150k miles. My 6.0 has black smoke and can barely crawl up a hill. Dealership is 30 days out for an appt. Air filter, oil change, alternator, and batteries are new. I removed the EGR valve and cleaned, but the valve seat is not perfect. I can see 20 to 30 mil gap around half of the seat. Is this ok or will that little gap cause this?
Hoses all look good. No alarm lights. I have no diagnostic tool but I can use a meter well. It did have an airbag light but I found the fuse missing and replaced it. The air filter alarm switch fell apart but I bypassed it till I get new part. No alarm lights now.

While I'm cursing at highway speed everything is fine. But when u punch it it pass someone it's like I actually slow down, same from a red light. I've got a livewire programmer in it and this problem is somewhat new. It just seems to keep getting worse, I was going up a hill on the interstate this morning and at 2800 rpms I was actually slowing down. I'm not sure if the fuel pump is going out or if the transmission is slipping or what.

Blown fuse causing a lack of power to the OBD port?
I just got my Kiwi2 BT OBD2 adapter and was hoping to start diagnosing my truck, but the adapter won't power on while connected to the truck.
I pulled and visually inspected fuse #12, I also verified power to the cigarette lighter plug and the accessory 12v power outlet.
The adapter powered up with no problem when I connected to a co-worker's Tacoma.

I have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?

Having some problems with an e-350 dying when in gear and rough idle. Truck starts up after it dies. Vehicle acts like it is starving for fuel. I have check fuel pressure after fuel pump and getting 55psi. High oil pressure pump with in normal ranges. Cleaned and checked egr and it was in the closed position. Fuel filters have been changed. Injector buzz test ok.

My 2007 6.0 has a really rough (almost 'miss') during cold start up. After 5 seconds or so, it smooths back out and sounds normal. Until gauge reaches normal operating temp - there is a surge/lack of power during light acceleration. I also hear a frequent compressor coming on and running for a while which I am contributing to a possible vacuum leak. Maintenance is always done on time and I've already had a few costly repairs (both internally as well as externally) on the engine. I usually always wait for the glow-plug indicator to turn off before cranking the engine and let it idle for 5-10 minutes prior to driving it. Once the vehicle climbs to normal temp. everything seems to be fine but the compressor still comes back on every so often.IS it worth simply replacing the vacuum canister located behind the passenger side battery - or should I find someone to hook up a diagnostic unit first?

I have a 2006 F250 6.0 Amarillo Edition. 133,000 When I bought the truck it was a theft recovery vehicle where the turbo, injectors, FICM and wiring harness were stolen. The company I bought it from replaced the injectors, wiring harness-new, and a used FICM, and turbo. Also has EGR delete and SCT tuner with basic tunes. I believe the SCT was put on to mask another problem. No dealer would spend that kind of money to sell a truck unless something was wrong. The truck would accelerate some with the tuner but shift the tires so hard it would bark them. I removed the tuner and went back to stock program.
The truck will barely move and takes a long time to accelerate under a load. In park and neutral it is fine. A friend has a ford diagnostic program on his computer and says the readings were all good except EBP was a little high. Removed exhaust and air intake to verify no restrictions. Turbo sounded like the vanes might be sticking so I replaced the turbo and VGT solenoid. Now truck feels like its trying to make more boost but not transferring power to the engine. Have blown the silicone hose off twice now during testing. Checked the EBP sensor and tube and only thing I see is a little carbon buildup inside the sensor. What else to check. I'm new when it comes to diesels.

I drive an 08 f-350 with 120k no tune or deletes..(yet). I was driving home yesterday when I all of a sudden I have a lack and power. I then notice i have no boost at all. I heard an exhaust leak and instantly checked my boots on inter-cooler pipes....
After farther inspection, the bolt fairy came and I am missing some bolts on my up pipe where it meets turbo. Is this break in vacuum system the reason I'm having no boost? What is easiest way to get to up pipes without removing cab? Where did the bolts go? I got to get this fixed because I need truck to get around town.

Recently I have noticed my psi reading on my tuner hovers around .25 to .35 in the morning right when I start my truck. Normally it reads zero or is in the negatives. After driving around and stopping at red lights it will hover between .80 and 1.25. Now, I know that not a lot but its not what it normally reads.
Last week I went off road and my exhaust took a hit and loosened up and caused a small leak near the rear axle. I unbolted it and for the most part fixed the leak minus some alit air flow coming from the slits in the pipe. I'm not getting any codes and haven't noticed any decrease in performance. It does however seam to slow down quicker when I let off the throttle. I'm running an SCT X4 with dpf and erg delete and have a S&B CAI.
I called a performance exhaust shop and the tech said a small leak shouldn't cause any issue like that especially because its so far back. Another respectable vendor told me it might be that my vein are stick.

after my DPF delete and fl0-pro 5" install, i've noticed a slight decrease in lower rpm boost. with the tune i have i can still get it wound up, but it takes a little "gettin on it" to get there. i miss the little bit of boost i had from stop lights and what not, or even cruising at 50 with a slight increase in fuel. i don't want to have to have it downshift in order to spool the turbo to get me that slight uptick in power.
i've heard differing opinions - "stock turbos need the 4" for more backpressure" ; "5 inches is great, b/c you could always use a couple extra inches" ; "there's no difference between the two, but you don't NEED a 5 inch until you're at 1k bhp".
i've got the 5" setup on there... that's that. how can i increase the reaction of the turbos? i've read about a wastegate adjustment (tightening), but not sure i'm ready to undertake that in the driveway, and i don't have access to a lift. nor am i sure this will correct my "issue." (i quoted it, b/c it's not really an issue, it's just a personal preference that i'm wanting to adjust to make myself a little more happy with the performance of the truck)

Truck = 2011 F250 150,000 miles, no modifications, stock.
Truck lost power yesterday, no boost, and no codes. When driving on Friday, I started moving from a red light. The truck seemed very sluggish. Then I noticed it downshift going up a small hill that it never downshifts before. I looked, and noticed the turbo gauge at 0, no boost. I pulled over, turned it off, then restarted it, but still no boost, and the truck is very under-powered. I looked over the area, and do not notice any leaks, also no leaks underneath. I hooked up my OBD reader, and no codes., the boost gauge is on zero, and the truck has lost significant power. I no longer hear the turbo spooling.
I have spent the past several hours searching sites and forums (Started with FTE ), and it seems that most believe a restart of the truck has solved it for them. However, this is not the case for me, a restart, even after letting it sit overnight did not resolve the issue.
I did see one reference that replacing a NOX sensor solved their problem. This brings up some interesting truck history. Back in June 2017, my truck threw the following codes, P207F and P20EE.
P207F - Reductant Quality Performance
P20EE - SCR NOx Catalyst Efficiency Below Threshold (Bank 1)
The message said I have 200 miles until reduced power. Since it was a Friday, not much I could do at the time so I let it sit overnight, and then the next morning the message was gone. I plugged in the OBD reader and cleared the only remaining code (P20EE), and its been a very happy truck until yesterday.
So my question, can a bad NOX sensor cause the issue of loss of turbo boost, with no codes? Is there another possible cause?

I have a 2006 f350 4x4 dually 6.0. The other morning when leaving for work I hard a loud air noise, like a jet. It only happens when the motor is trying to create boost. I have NO boost. No smoke. If I push the fuel pedal past 1/4, nothing. Its like its stuck and no more power at all. I have changed the boot from the turbo to the intercooler pipe. (looked like it had cracks in it). Checked the cold pipe, no cracks seen. Check the exhaust clamps, into the turbo, they are tight. The turbo is seeping oil around the seal. I took the inlet, fresh air, pipe off. Check the turbo spool for looseness, fins, spun the wheel, ran the engine and watch to wheel. Seen no issues. Where to go now?? No coolant leaks, no oil leaks.

I have an issue with my 6.0. I was running the extreme street tune from IDP for the past 2 years now and recently purchased the xtreme X tune from IDP. I loaded in the tune and had low boost, low power and horrible acceleration. Max boost i would see is about 10psi and it would take about a solid minute to reach highway speed when merging on the highway. I went back to the stock factory tune and have the same issue. No boost leaks from the boots or pipes and no check engine light. What is going on?

I have an 03 6.0 Power stroke. My problem all started the other day when I started to occasionally not get any boost on acceleration and lose of power and a lot of vibration like it's about to cut out but it got worse now today I drove it about 5 miles into town when I got to town I noticed a rough idle I got gas in a gas can not in the truck. I got back in to leave and I had absolutely no power at all the truck stalled out and it was very hard to start finally got it started and it runs really rough almost like it's going to shut off.
So when I started driving I would only make it about a mile or so with out it chocking out and having to let it site for a minute or two and start it back up and go another mile or 2 and have it do the same thing all the way home all the time I have vary little boost if any at all except for when I first pull out now oil pressure is good and engine never over heated some of the codes I have is an EGR code and a contribution balance code for several cylinders I was thinking possibly a maf sensor or a clogged egr not working right.

Having this problem, what to do to correct it? There is no hole in the boot and this just started about a year ago. Does not do it all the time.

I was driving and went to accelerate quickly and had no power, checked the boost gauge and it had very low boost. Continued like this the rest of the drive, all gauges normal, no check engine light, not towing or hot. Got home then next time out it was back to normal.
Someting to be concerned about? Or just a computer hiccup. Truck is '13 with 66k.

I am currently stage 2, drive my car kind of aggressive on a regular basis, and now I hear a squeal under high boost, sounds like air escaping. Boost is not acting any different, I've come to the conclusion that the problem is most likely my revision D DV.
-What does failing REV D sound like???

I've got an 05 EX 4x4 150k miles. Stock tune, EGR delete only ....
Driving along and everything was good plenty of boost no power issues. Got off the freeway and truck just stopped making boost. So I messed with it for a couple days. Cousin with a Mac scanner flaked on me so I was stuck using Edge gauge cluster and trying to trouble shoot.
NO CODES, No smoke, EGT's rise and truck seems like it is lean. Boost has fluctuated between 4psi to 11 psi. What should MAF be at idle?
ICP has been consistent with whatever boost levels were being made.
FICM 47.5
New MAP tube/nipple cleaned
New MAF
Clean Air filter
New fuel filters
VGT actuates
Accel ped in spec
Turbo spins free
New hot side CAC boots
