No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Here is the story. I took my truck and trailer on my yearly fishing trip to wishon lake. As i was going up the grades my truck made a scrubbing air sound from hte passangerer side of the truck turbo / air box area at the 3100-3300 rpm mark. finfished the trip and took it into the dealer they were able to make the sound and as they were driving back the shop it died in the road this was tuesday 10-27-09. Well the tech is working it and said no fuel presure and my oil is way high . they asked me if there have been a lot of regens. I said yes i get about 3-4 a tank of fuel. oh that explains the high oil you must have a bad sensor in the dpf system. so i said ok well why did it die ? well you might have a leaking injector and the system wont build presure ( bs ). Well as of today 10-30-09 they tell me the cab needs to come off because they cant figure out what is happening and why there is no presure, so i chewed his ass, its been there a week and you still have no idea whats going on ? i thought it was the injector or the fuel pump bad sensor ... which one is it .. " well sir welll , well " I said no wells fix the damm thing . does any one know of a dealer that has techs that can find and fix problems on the 6.4? im in fresno Ca. This is flash backs to the buy back Ford did with my 6.0 that was in the shop 3 times a month. I will not go through that crap again! Please give me your feed back.....

Sounds like they're on the right track, to be honest. Excessive regens can cause fuel dilution and an overfull crank case, but the injector can as well. If the oil is "way" high, that sounds more like a leaking injector or fuel line than too many regens. If there is a bad injector, it can take out (possibly melt) the piston/cylinder if not caught quickly enough.
I would think that the amount of extra soot that cylinder could be putting out (if the injector were bad) may back up the dpf, triggering the regens as well. I doubt it's a sensor in the exhaust, but if they want to replace them, I wouldn't argue.
If it were my truck, I'd want the cab off, injectors tested, affected cylinders inspected, & oil changed (obviously). If, after the repair, the excessive regens continued, I'd focus on the DOC and DPF.
Well the truck still sits at the shop. the tech said he will not pull off the cab until the Tech from Ford comes out Today or tomorrow, to find out what the heck is ging on. The tech that has been working on it has preformed every test and everything checks out ok all the sensors everything fuel presure is fine no leaking injectors nothing .He has also done everything the ford hotline told him to do too. The truck will still not start just turns over . Any ideas, working on week two at the dealership.

Well the cab was taken off and a new fuel pump and wire harness installed This is what the hotline told him to do. They did not even send out a tech when they said they would. The tech put it all back together and started the truck. ran for about a minutes then died. now it will not start just turns over. It has been there for a little over 2 weeks . anyone have any ideas?? They said a ford tech will be out monday ... right.. I have some pics of the cab off, check them out.

This is what scares the daylights out of me owning one of these.
For the small amount of towing I do, I am seriously considering trading in for a 2010 F350 V10 gasser.
You must have an extremely large headache by now. I wish you the best of luck and I hope the problem gets resolved quick.

Interesting photos. The part I have a hard time with is the fact that with the no-start condition, it has to be throwing a code that is useful in the diagnosis! There was an issue with a wire harness that was causing a no-start condition. Here is a quote from that.
Quote:
Some 2008 F-Super Duty vehicles with 6.4L Power Stroke Diesel engines built before August 20, 2007 may experience a check engine light on, a lack of power or no start condition. The affected vehicles have engines that were assembled using a fuel pump cover gasket that has unprotected wiring that may chafe on the fuel pump causing a grounded circuit. See photo on the right. The circuits involved are the power supply and the control circuit for the volume control solenoid. A grounded circuit will cause driveability concerns and may set DTC's P0003, P0004 and P0091. Technicians servicing the vehicle may also discover fuse #74 at the battery junction box open which is the VPWR circuit for several engine components including the Volume Control Valve (VCV), Pressure Control Valve (PCP), Glow Plug Control Module (GPCM), EGR Throttle Plate Valve, Electronic Fan Clutch, Turbo Charger Actuator and the Mass Air Flow sensor (MAF).
On December 13, 2007 Ford issued TSB 07-26-2 which provides the part number for the new fuel pump gasket. Below are the old gasket on the left and the new gasket on the right. The new gasket has added protective tubing over the VCV wiring. Owners and technicians should understand that the repair procedure to replace this gasket requires cab removal to complete.
Have they checked for any blown fuses as stated above??

Thank you for the information about the tsb. I will call the service writer in the morning and pass on this information about the fuse and location. This is driving me nuts, this has been the only problem i have ever had with this truck. the truck has always ran great. I only have 46000 miles on the clock. Another note, the service manager said i need to change my oil every 5000 miles because on the regen and diesel getting into the crank case when they checked my oil he said it was over full by 4 quarts. Could the egr cooler have anything to do with my issues ?

The oil-dilution from fuel contamination, unfortunately, is part of the regen process. Nothing to do with the egr cooler. 5k is definitely the max with the dpf/regens still in place. How many miles were on your current oil, to get to 4 quarts over? (Though, wasn't it regenerating a lot more than it should have been, recently?)

I was changing my oil every 7500 on the mile, and yes i would get 3-4 regens on a tank of fuel. I will get it done at 5000 from now opn , if I have a truck to change it every 5000 HAHA. any way Im calling the dealer now to tell him about the tsb , it is 09:15 west coast time here in the central valley Ca. I will keep posting what I find out.,

Listen to this.... Now ford is asking now for my service reports for oil and fuel filter changes. I asked why ? Well they want to see if you are doing it on time... they are saying that fuel filters are to be changed every 10000 miles ? What all my paper work said 20000 miles and they were just changed just 15000 miles ago.. What the hell are they trying to pull? I have been on my maintance schedule down to the mile just about. Why ask for all this now after it has been there for over 2 weeks and cab removed and fuel pump changed and oil changed ....If this goes on any longer im getting a lawyer i will not have a repete of my 6.0 nightmare.

I feel that their intervals listed are way too long, and change my oil at 5k, fuel filters at 10k. Even so, the manual states oil changes can go 10k and fuel filters at 20k. So you're still in the right. I would provide whatever documentation you have, since you're still within the longer schedule. (Though for future reference, I'd go to the severe schedule for piece of mind.)
I've heard of a few people who have had those documents requested, when others chimed in and said that means they are covering the costs. I guess it's standard procedure that they (Ford higher ups) ask for that when they are footing the dealers repair bill. I wouldn't argue with anything yet. Just play it cool and act like you KNOW you're right, since they have no arguement whatsoever. I doubt they are approaching it from a negative point of view. Just going through the motions, so to speak, and verifying before writing the check.
