High pressure oil leak?
 

I had problems with my high pressure fuel valve in oct we changed it ran great. My guy didnt change oil so valve got plugged up again. Oil change and new filters it ran fine. last week i had an injector changed and two days later i drove it and stoppped wouldnt start. i sat for a bit then it fired up. no problems till this weekend i drove for an hour parked and shut off no start. had towed to house i pulled turbo and changed high pressure valve no start still. Im getting a scan tool tonight. Im going to pull valve and crak to see if oil is flowing. any ideas on what to check. This thing is getting to me.

Typically a no start when hot condition is a high pressure oil leak. The 05's were notorious for the STC (snap to connect) fitting on the HPOP under the turbo. If you dig in to do the STC fitting (upgraded kit available from Ford) I'd also throw in the upgraded stand pipes and dummy plugs. I've posted both the P/N's for these kits in the last week in the threads below! Depending what you get to scan, you can monitor ICP desired and ICP actual to see if you have a leak, or you can hook a 12V source to the IPR valve, close it, and hook shop air up to the high pressure oil system and listen for leaks.

Welcome to DB!

Ok so we scanned it and found nothing out. No easy find have base pressure. So i took out pump and changed stc fitting after we air tested> heard a hiss. With pump out i didnt see any metal. I did think oil was shinny. new stc and pump bolted down cranked it twice and she started. Cover back in and starts up easy. Ran it for 300 miles the last 2 days. Then with no warning it died no smoke and wont start again let sit all day. Had to be pulled by a HEMI into my job site im at my breaking point. Whats my next step? hpop or oil sensor or crank sensor or major rebuild. I ve spent way to much on it to give up now only 167000miles Four injectors a new harness, stc, new high pressure fuel reg, other thing that have slipped my mind nothing to due with it not starting. Let me know or call me 978-866-4049 names james im not sure if i just want it towed to ford or if my guy can fix it. Thanks alot.

Typically just throwing parts at it wont fix the issue, this will usually just lead to further frustration.

You scanned it with a real scanner, or you put a code reader on it? No easy find have base pressure? What does that mean? Did you monitor ICP desired and ICP actual, that would have told you if you had a high pressure leak. Hooking air up you will always hear a hiss if you didn't put a 12V source on the IPR, you're gonna hear air going right out the IPR.

Since it's died again, are you getting any smoke while cranking? Your next step? Probably none of the sensors you just mentioned, why do you think it would be one of them? Are you getting codes for those? You can't just throw parts at it and expect it to work.

Diagnose, verify, repair. I can see why you've spent so much, throwing parts is a good way to do so!

lets take a step back and look at this logically. Scan for codes. let me know if you have smoke coming out of the exhaust when cranking or not. Your new injectors and harness, why were those replaced? My guess is you have FICM issues and half of the stuff you've replaced wasn't even needed.

We can get this resolved.

I need to know these things next time you post:

ICP desired vs. ICP actual, and IPR duty cycle while cranking

Are you getting smoke while cranking?

Test the FICM voltage, you can find the test procedure at the top of the 6.0 page.

Im getting the info off scanner it was scanned with a matco scanner the guy in a mechanic so its not a 100.00 tool. No smoke. Ill have the shop take a look at ficm and check it. I had to send it into a guy i know cant run a company with a limping truck. let me know of any more ideas on what it could be.

---AutoMerged DoublePost---

The scanner read O actual and desired around 900 ipr duty cycle around 35 then jumped to 85.

Definitely a high pressure oil leak. I'll bet it's the High pressure oil pump. The truck is asking for the pump to make 900psi (only needs 525psi to fire), and your actual is 0 because nothing is being pumped... the IPR duty cycle will keep rising up to a max of 85% trying to get more oil going, but if the pump isn't running, then that wont help.

I would first try and test low pressure oil... as it's cranking, if you're not getting smoke this tells us the injectors aren't even moving. My gut says high pressure oil pump is shot, but of course if the low pressure oil is shot, and not feeding oil to the high pressure you can't build pressure either. When you're cranking, (or your guy) have him check and see if the oil pressure gauge on the truck is going up, if it goes up, you've got low pressure oil and no high pressure.

I would replace the high pressure oil pump, the dummy plugs/stand pipes and the updated STC fitting if it hasn't been done already, let me know if you need the P/N's. :c:

Its at shop now wont be torn down till next week but ill post what he finds. Cant wait to get it back with no worries. Im having hp oil system rebuilt new pump and any o rings and tubes egr delete and lets hope thats all for this year. should i have them put a tuner in while its in? not looking for power just fuel mileage. I travel two plus hours to some jobs and fuel is around 4.18 a gallon. So thats easy three hundred a week in just fuel. Any ideas on how to get a bit better than 380 miles out of 28 gallons 12 to 14 per gallon now or just get a prius.

I'll tell you what was told to me on the first powerstroke forum I ever signed up on, and I should have listened...

"Never mod for fuel mileage. Mod for power, and if you get some extra MPG's, be very happy"

Now with that said, I bought a tuner with the hopes of "2-4mpg increase!"... yeah right. Could you gain mileage? Probably. Will you? Probably not. It's a catch-22. The hottest tunes available (via custom tuning with an SCT), offer the best mileage, but only if you can keep your foot out of it. Once you've gone WOT on an x-race tune or something similar, the smile is hard to wipe away, and WOT runs become more addictive than crack.

You start with a small tune, then it's not enough, then you're into the hot tunes, then your headgaskets are blown, now you're putting ARP studs in... it just keeps going.

If you want to do a tuner, you can do that yourself at any time, no need to have your guy do it. Very simple. You get tunes via email, load them from you computer to your SCT, then from the SCT to the truck, very simple. We can help you with that too.

I say get your oil issue resolved FIRST. Once you've got that squared away and know there are no more issues with the truck, then we can talk tuners. :c:

Your mileage isn't really out of this world. I get between 13 and 15mpg. 29 gallon tank btw. You're probalby not recording fuel mileage correctly anyways (if you are, my apologies), most people don't realize that when the pump clicks off the tank isn't anywhere near full. The only true way to record mileage is to keep filling... keep filling and filling and filling, very slowly to avoid bubbles. Stop once you see fuel resting in the fuel filler neck. That's the ONLY way to get it to the same spot every time. If you're just filling til it clicks off, your fuel amount in the tank is different every time.

EXACTLY:c:

I put twenty four gallons every time i stop a truck stop and i know she wont go much more than 340 miles till the light is on. Good to know i have 29 gallons that extra gallon may make a diffrence one day. So i know i have five gallons when light comes on. I fill it till it almost spills out so i know its full. I live in Vermont fuel is hard to come buy a a cheap price. What type of power are we talking out of this tuning? I pull a five thousand pound trailer through mtns weekly id like to not even know its there. Sounds like i need to get it tuned after i get i back. Do you know what size tire i can squeeze under it stock? What tires are good for a lot of miles? I seem to get a year and a half if lucky.

leveling kit and 35s:c:

Thats only like an inch bigger than stock. More the question is what brand. I eat them up like they are too soft. Have goodyears now had coopers neither one seems to last or i just drive too much. Im saying in 15000 they are junk i rotate and make sure psi is good every month. I need new ones again so any input would be great.

stock tires are 31s

I have run Firestone Transforce AT tires on mine ever since the OEM tires wore out. I would get around 65,000 miles out of a set. This time I put on the HT instead of the AT just because I could not get the ATs. During the summer months my truck is in MT pulling a horse trailer with 8 horses in over the mountains.

You can fill it til it spills out of the neck, but it's only doing that because of the foaming inside the tank. AFTER the pump clicks off the first time, it takes me almost another 10-15 minutes of slowly filling to get fuel in the neck, this is part of the reason why I stopped checking mileage, too much of a PITA. I promise your mileage recordings are inaccurate. The only good way to do this is have fuel resting in the fuel neck. We're talking a difference of 3-5 extra gallons once the pump has clicked off the first time.

What type of power do you want out of tuning? You can't tow on a really hot tune, or at least it's not advised. They do make some really nice towing tunes though, they'll firm up your transmission quite a bit and allow some real good use of that turbo like an exhaust brake. I LOVE towing with my aggressive tow tune from Innovative Diesel. I always use this when towing my camper (maybe 5k lbs when loaded up). A hot race tune will be in the 420/430 rwhp range and almost 800 ft/lbs. However, there are quite a few preventative things you'd need to do before diving in. Gauges are one main thing. Get your truck running first and we can go down this road...

A towing tune would do you wonders though. Keeps the converter locked up a lot longer, holds gears longer, uses the turbo as an exhaust brake, really lets you use your truck to fully take control of the load behind you. I have even towed a few times on a street tune, it's almost too much power for towing on public roads. Gets the trailer up and moving in a hurry. My tow tune I've had my camper accelerating up the hills in the adirondacks, I let off at 70mph and EGT's were still only about 1100*. I was amazed at how well it pulled up the hill. I've even passed a few cars with the camper behind me. The look on the face of the people getting passed is usually pretty funny. Not that I'd recommend that kind of driving...

As for tires, what are you using now? I just put some Pro-Comp extreme A/T's on mine, they have a 40k mile warranty and are made in USA.

Yessir, that's what I'm rocking now. 2.5" billet spring spacer up front (leveling kit) and stock F350 blocks in the rear (350 blocks are a little taller than 250 blocks). 35x12.5x17's.

They're quite a bit bigger, trust me. What Goodyears you using? Towing obviously accelerates wear. Wait til you load a hot street tune up, your rear tires are going to hate you.

I'm moving this to it's own section. :c:

The best tires I have used were the stock size and brand on my 04, they are the BF Goodrich rugged Trail, had 2 sets of them both lasted for 120,000 miles and only changed because it was close to winter and wanted deeper tread to make sure I wouldn't get stuck. There are several ways to get good mileage out of these trucks, exhaust mods is a quick way to make an increase and with a good tuner it can be done, just have to keep our foot out of it, a little romp every now and then isn't bad though, helps keep the turbo clean. I have 253k on my truck and still get 20mpg normally, took a trip fot the Daytona 500 this year and managed to get 24mpg at 75mph, I have the 29gal tank too and fillit to the brim everytime, normally go 500 miles and put 25 gal in it. does your truck have 373 gears or 410s that will make a big difference too.

gana have to throw the BS Flag

Bob wouldn't BS us. He's one of very few I'd trust. He is also running an 03 with (I'm assuming) older programming, which helps and he daily drives on a race tune, so the converter is locked up all the time, which is a lot more efficient as well.

Plus he drives like an old man! :moon:

24mpg at 75mph... NO WAY

you have to drive with a light foot and no cruise control, lift to keep it at speed when going down hill and lift so you bareley need the brakes when exiting, i run on level 4 with the Edge, Amsoil in motor and diffs. 80psi in rears and 70 psi in fronts. on long trips i drive like an old man, yes, but it sure sounds good going down the road. I know a budddy of mine with a later 04 lost 3 or 4 mpg when dealer reflashed his truck so I never let them do that to my truck, only one done was to eliminate the EBP sensor, find out what that one was and get that tuning. Normal driving to work and back home I get 20 mpg almost all highway and usually about 45 to 60 miles one way.

I get around 15-16 daily running around. I have managed better than 21 on the highway, however this was driving from where I live in NY to Woodsville NH. On "my" truck I have to keep it at 65mph, if I run faster my mpg does drop. This is far from a straight flat trip, there are some hills along the way. I would love to make the I-80 run from Omaha to Cheyenne just to see what I could get. I am sure that with the older truck-older strategy, race tuning-locked converter and the right driving style I could get 24mpg.....But would I be having fun?:nope:

i get 16.5 highway... at 85mph

I wish there was somewhere around here that I could run at a steady 85mph long enough to be able to figure my mpg....just to see.:humm:

i run 83-90... never slower than 83 unless a work zone:tu:

Insert face into palm...

My apologies here, I'm confusing members again (long day Friday eh?)

This post:
I was thinking papachuck, not Bob, thus my comment about the race tune use.

I'm actually going to agree with this, never seen one get 24mpg EVER. I know Eric from Innovative was able to get a 2x4 truck into the 22-24mpg range, this truck also had larger injectors, a larger turbo, and this mileage was recorded running 50-55mph on flat ground between two shops. He said if you got into it at all, it dropped dramatically. I can't see a stock injectored truck doing this. Especially on an Edge, but I've been wrong before.

This is the guy who I was thinking, when I was posting about Bob (not that I don't believe you Bob, but it's one of those things it's hard to believe without seeing).

I hear that. I found one place near my hometown where I could do a 100mph for a short time. I wanted to see what RPM's and EGT's were at 100 steady. :c:


If you're getting 24mpg out of any 6.0, hold on to it with dear life and don't let a dealer reflash that thing for anything.

I think that with the tanks on our trucks being such a pain to get full, alot of people have a hard time figuring their mpg. I was with a guy who filled his tank, said it wouldnt hold more and it was up in the neck. I shook his truck and fiddled with it and got 3 more gallons in. Over a 100 mile run 3 gallons would make a huge difference and it could be either way depending on which end of the trip you put the biggest effort in filling the tank. I honestly believe 20-21mpg is possible for most trucks depending on how hard you try, tuning and terrain ect. 13-15 is probably more reasonable for most people. Would I call BS on the 24mpg claim? no I wouldnt, but I would say repeat it a few times and be very sure the tank is full every time. Just to be sure of the results.

I have used my totally stock (Except for K&N air system) 06 6.0 for both commercial hauling and as a DD and I watch my mpgs very closely, especially when I was figuring the cost/mile to run the truck for business.

I do fill to the very top of the neck, shake the truck and fill until most of the time the cap pushes a little fuel out. The best I can get is 17.5 mpg if I run right at 2000 RPM (OEM Tach). The ONLY time I ever did any better was in Maine one day when I was driving a two lane and had time to kill and I hit almost 20 mpg but that was the ONLY time. The worst the truck ever did was going from Phoenix to Salt Lake grossing 26,000+ pulling a 28' goose neck in FWD during a snow storm and that was just over 9 mpg

Papachuck you don't want to make the I-80 run from Omaha to Cheyenne you will be fighting a head wind you want to go from Cheyenne to Omaha and catch the tail wind:tu:

I was just thinking long, straight and flat with few stops but a tailwind couldnt hurt.

Just get west of the Mississippi - I90 in SD & I70 from St Louis will both have less traffic then I80 which is a MAJOR 18 wheeler route. Came across I90 in SD one morning and went 130 miles before I even saw another vehicle. Just bring a piece of rope, set the cruise to the speed you want then use the rope to tie the steering wheel then take a nap or read a good book :)

10.6 mpg that last tank...

---that includes *all honesty
-going 118mph
-going 100mph 5+ times
-doing 15 WOT's
-driving around town
-being stuck in mud, reving the F*%k outa it trying to get out
-leaving it idle for a total of 5 hours to keep my girlfriend warm:w2:

I got this mileage on one trip, I don't get it all the time. I left from my house in maryland at 3am and drove straight through untill deep in South Carolina then refilled, worked out to 23.84 mpg, have it written down. I stayed at 5mph over the whole way down, speed limits were from 55mph to 70mph, not 70 the whole way down, maybe a third or half way at most. straight down 95 wich is allmost flat for those that don't know that.I do run on Race with the Edge, it is level 4 on it. I fill it up all the way, I know how to burp my truck and I have the weight to move it around. Keep in mind I don't have any fancy grillguards or anything killing my mileage, I have a fold up bed cover on it and I keep the tire inflated to 80psi on rears and 70 psi on fronts,
