I have some scope traces of a truck doing this except mine was just stalling at idle intermittently. It was loosing SYNC and then stalling and I thought I had two different problems but it was the injector causing noise on the CKP & CMP signals. I've been lazy about posting them but since you brought it up I'll get them on here by the end of the week, I need help setting up the scope too, I had a real hard time getting good pictures.

I can't recall any truck using that much oil unless the turbo turbine wheel was missing and the complaint was not using oil-it was smokes and lacks power. I would agree that oil can't enter the fuel rail but I never say never with these things.

It sounds like the high pressure oil system was in failure management mode with ICP and ICP desired reading the same with a high IPR duty cycle, if I'm reading that right. Since the ICP was reading correct after running up the RPM I would guess the IPR is sticking, maybe R & R the IPR and check the screen. Good Luck

I just read the message about hijacking threads too. Sorry to pile on.

I just saw this thread. That is not how I spell "potato". I don't think I know anybody that spells it like that. Don't worry though, I'm sure everyone else is weird, it's not you.

First thing that comes to mind is a leaking copper washer letting combustion gas into fuel system, maybe the last injector wasn't torqued, or bolt for hold down streched, or bad cup. Doesn't sound like air in fuel but I can't think of anything else right now.

FWIW I have always been able to duplicate EGT 13 concerns when the truck goes into regen, but without a DOC I wouldn't think the exhaust would heat up much during regen.

I had one with a long crank time which was slow to build HP fuel pressure and that was a bad pump. It was under 10k miles and didn't have any debris in the fuel either. If the owner had ignored the long crank it might have failed completely with more miles.

I'd like to see Ford release pre-mixed antifreeze with distilled water already mixed in. It seems impractical for every dealer to have a water processing plant for doing cooling system services.

I thought I would just add that excessive fuel in the crankcase also wears out rocker arm and pivots from lack of lubrication. They usually occur high mileage and might be out of warranty before a failure is identified. Just something else to think about besides total engine failure.

Good stuff. I don't think I've ever thought about monitoring amperage draw with a intermittent blown fuse concern like that. I usually just tie in fuses like you did until the faulty component is found. That's something else to add to the bag of tricks.

The only time I've replaced a MAF sensor was for failing during the EGR test. I don't think the MAF sensor was a casual part for any concern and I was running the EGR test just to verify other repairs. I did replaced a MAF on a 6.4L once for excessive regen after running the PP test. I don't think that fixed that concern either, it was just customer perception-it was a 450 that towed a race car trailer on the speed limiter all the time.

Was the dirty MAF related to any other symptoms besides not being able to run KOER test?

If they really are hurting, I'd remove the clutch disc, field, and pulley then reinstall a new pulley only. That will keep them going and if you feel generous you could give em a break on the labor. You reap what you sow or something like that. I'd think they would be back pretty soon since your in South Carolina. Nothing quite like a hot bus full of people in their Sunday best.

The customer never came back so I guess he's someone else problem. I'll just have to check OASIS in a couple of weeks to see what was replaced. I'm just not sure why the oil pan would crack to begin with, another unsolved mystery. Thanks guys.

I give my writers alot of latitude but I go absolutely crazy when they take a truck out of my stall without my permission. That doesn't happen anymore. If I put a truck outside that I'm not done with I always hide the keys on top of my box to keep that from happening.

I had a truck today that was brought in for leaking oil and customer stated oil pan is cracked. I find the glow plug grommets blown out and let the customer know he needs to leave it for major engine repairs. I didn't really look very hard at the oil pan since there is oil running down the side of the engine but the customer insists the oil pan is cracked also. He comes back and shows me what he saw and sure enough there looks like there is a crack in the oil pan just in front of the drain plug. It looks like a stress crack but may just be crack in the paint/liner that is holding oil. It wasn't dripping oil but when you apply pressure oil seeps out. I didn't have time to clean the area and recheck it for oil leaks. The customer wanted to take the truck and bring it back next week to leave it for the engine repair. I have never seen this and there are no witness marks from impact, the pan doesn't look bent, and corrosion isn't a factor in our area. Has anybody else seen this or something similar? The customer said he had another truck that had a crack in the same place also that was leaking oil--that struck me as very odd. The truck has about 175,000 miles and had a shortbock installed at another dealer about 30,000 miles ago, and he has a 200,000 mile diesel care warranty. Any ideas are appreciated and I'll probably have the oil pan off when fixing whatever is really wrong with this engine.

I usually can determine that oil flow is not restricted to the HPOP from the reservoir by watching the oil flow out of the supply port after removing the HPOP. If there is a steady flow of oil out of supply port without any pressure then I would assume it would have flow under pressure. BTW I had old style pump bad a couple of weeks ago that made absolutely no pressure and saw no sign of failure but a new pump fixed it--it's like the shaft inside the pump is broken but I've never taken one apart.

Do you have SYNC and FICM SYNC? There are some great threads on here about checking and fixing cam and crank sensor signal problems. Not really enough information to help much.

Not really common but I have seen a few, and normal people don't continue to drive a vehicle like that. Might be better for you that they declined the work.

Sounds like bad information from what I have seen. If you go to the Ford website for the release of the new truck they show the new PTO option and talk about all the great stuff you could do with it. Maybe your old service body won't fit on the new chassis and you'll just have to get a whole new truck. I wouldn't believe Ford is willing to give up any market share at this point.

You can get those from Dell. Try this USB cables I also found this info on the Dell website and maybe you could Google it and get it somewhere else. Manufacturer Part# CF-K18CB002 Dell Part# A1486264

I've done several with no problems. I think I read somewhere that whoever manufactures the pumps was worried about the solenoid being grounded and the pump run at full pressure causing damage to the pump. After inspecting several pumps they said it didn't cause damage. That's just what I hear. Removing the cab isn't that bad the second time around-unless you put new bolts in like you're supposed to.

A businessman met a beautiful girl and agreed to spend the night with her for $500. They did their thing, and, before he left, he told her that he did not have any cash with him, but he would have his secretary write a check and mail it to her, calling the payment "RENT FOR APARTMENT." On the way to the office, he regretted what he had done, realizing that the whole event had not been worth the price. So he had his secretary send a check for $250 and enclose the following typed note: "Dear Madam: Enclosed find a ceck for $250 for rent of your apartment. I am not sending the amount agreed upon, because when I rented the place, I was under the impression that: #1 - it had never been occupied; #2 - there was plenty of heat; and #3 - it was small enough to make me feel cozy and at home. However, I found out that: #1 - it had been previously occupied, #2 - there wasn't any heat, and #3 - it was entirely too large." Upon receipt of the note, the girl immediately returned the check for $250 with the following note: " Dear Sir: #1 - I cannot understand how you could expect a beautiful apartment to remain unoccupied indefinitely. #2 - As for the heat, there is plenty of it, if you know how to turn it on. #3 - Regarding the space, the apartment is indeed of regular size, but if you don't have enough furniture to fill it, please do not blame the management. So, Please send the rent in full or we will be forced to contact your present landlady."
