The truck is a 04 f 450. the problem was diagnosed as 2 bad injectors. the truck was lacking power. I belive the next problem was the person that installed the injectors. when the new injectors were installed the truck was tested. and a whole new set of problems began. when the truck is started it runs its best at the very begining, which isnt very good. it slugish and lacks power but is a smooth power curve. the more it warms the worse it gets. until its to the point where it obvously missing and shaking and wont get over 750 rpm power brakeing. my theory is that the person that changed the injectors didnt us new seal kits on the injector or didnt torque the to spec. and combustion gas is leaking into the fuel rail. according to what iv been reading. Is there a way to tell if the combustion gas is leaking into the fuel rail? and is there a way to tell if all the injectors got damaged if the combustion gases were escaping into the fuel sys.? I dont work on the 6.0 much and i trying to do a favor for my uncle. I would appriciate any advice. thanks
seals come on the injectors, unless is some aftermarket junk that doesnt, yes they guy could have not tourqued them all they way and it could be doing that. als ive seen injectors right out of the box allowing compresion to go through them. usually the engine wont run for long before it stalls when this happens though. easiest way to check is unplug your fuel pump and take your fuel filter out on top of the motor, watch the fuel in the filter housing while you have someone crank the engine over and look for bubble comming up from the bottom.
i would also check fuel pressure and your filter.

Hey fordboyyfm
Am having a problem[I think]
Following is situation 2001 F550 7.3 65000mi cps recall 09/04
I was demonstrating/ Training a MODIS to one of my customers last month ang showed him the buzz test [ this was on my 550] and got the 9 buzzes. While scanning data I noticed a per del readigs as follows 1 thru 7 .01 to.03 #8 5.3to5.8 Cyl contribution test gave me a PO284 [low fuel??] Truck runs strong and would not have known this "problem' existed if not trying to help someone out.
Took truck to my local dealer and they scanned it wiyh "GEM" [I think} They found a histotic code for quad driver [dtc1670 I think thats what the tech said] His contribution test did not show up any problem w/ #8 but he said that wasn't always a valid test
I had the rusty tank problem but when I built the truck in 2001 I installed a coleasing filter in line and never had any "stuff"'in the engine filter.
I am headin off to Alaska in June for a 5 month trip and dont want to be in Homer AK with problems I can correct now. Could this be a 'phantom code' or should I worry
What say you????
Thank you for any help

did you clean the filters in the fuel sender when you replaced the tank?
could do a compression test and test for excessive crankcase pressure from blow by but with low miles probly would just need an injector. cant say your not going to have a problem in the future but if its runing fine i wouldnt be worried about it.

Dealer said low fuel del before I changed the add-on filter After filter change it was a new truck Took sending unit out and cleaned the bronze p/u screens as a precautionary step I understand FOMOCO has a reasonably priced replacement tank now and am going to0 change before my trip.
I read on some of the other sites that the International cps clears up the # 8 cyl per del
readings Dont see why but there are a lot of people out there with a lot of answers Also some one wrote in on one site and claims there is a hose kit to get more fuel to # 8 Pressure builds when volume is satisfied so I dont understand that one either about the hose
My thoughts are like you said "If it aint broke..........
Changing my rear end and tranny oil to synthetic
What say you?
Will stay with Rotella T 1540 and chane at 3000 and filter at 6000
thanks for all the help

thanks for the tip.Ill disconnect the pump and try to see if any cylinder pressure leaks into the upper filter housing. hey i dont have any scan tools for the ford and i was wondering if there was a conventional way to tell which cylinders are missing? if there is combustion gases getting into the fuel rail do you think all the injectors should be changed. if the injectors are the problem what should the injectors be torqued too. its in 04 but i think there are two different specs for that year. i was woundering how to tell the two generations apart?
I did what u said to check for combustion gases and it doing what u said. I can even see the exaust coming out of the bubbles. I guess the next step is to pull out the injectors. do u think i will be able to tell which ones have been leaking by finding traces of soot that was blowing by the copper gasket? Or is there a way i can tell which ones are the problem injectors without having electronic tool for this truck? thanks for the help. Now i only hope the injectors were the root problem with this truck to start with. its like taking over someones monster that they created into a nightmare!!!
