i don't want to take the turbo etc out, i would prefer to use some engine flush products to clean passages

is there anything that works on diesels and the 6.0 that will clean oil passages

 

With 5,000 mile oil changes, CJ-4 oil and OEM filters you shouldn't need a cleaner.

 

so i desire to flush before spending money

any luck anyone?

 

I used to flush out gas engines by adding a quart of dextronII or marvel mystery oil. The dextron would really clean them up, piston ring landings and all run them for around 30 miles and dump the oil and refill. Being this is a diesel that is using oil to run injectors ect I'm not so sure if its plausable or not. I don't think anyone is going to endorse your idea, you might try doing some research online to see if its doable or just a bad idea.

 

i suspect that, because the injectors are hitting almost 900psi at all rpm's that...
i would hope that between a flush of oil and a new ICP sensor this eliminates.

from my previous post

2003 f550 6spd

The truck for 3years has been blue smoke when not hot. Recently (last winter) it was getting tough to start, (not if it was plugged in though). Pulled all intercooler hosing, soaped and armourial to inspect for cracks. All fine. Drained water fuel. No change. Cleaned EGR, nothing.
The dumb part is it works fine sometimes
So I purchased a autoenginuity it is giving P006a Undocumented Trouble Code.

a long list and thanks for reading, any and all comments thoughts welcomed and appreciated

AMSOIL Engine Oil Flush Procedure

 

You could dump in SeaFoam, Kreen, Marvel Mystery Oil, Hot Shot's Secret, or Lucas. I wouldn't do it, I like my injectors too much to feed them that. If you're cool with buying 8 new sticks, go for it.

If it's injector stiction causing rough starts, using Rev-X is the stop gap before replacement.

so which will it be

as the truck has the smaller alternator, with extra lighting for at night
we use some more electric power on it

and that it can run correctly sometimes
now only unboosted

therefore a signal to allow boost seems the culprit


i am still unsure of the oil system flush, but i do think dirty high pressure oil pump being clogged.
but, is it worth new "O" rings all round???

 

What is going on that you feel you need to remove the turbo?

 

since owning the rig, it sputters from a start, to a hill through 3ed gear, 2nd it still has a tough time sorting how much fuel and boost to allow. It feels itself out near 2,200 rpm more or less it smokes.
since last winter, starts have been getting tough, and lately it will not allow fuel to match boost required.
140,000mi on the truck, little or no maintenance before i got it. except oil changes i have been told.

my AutoEnginuity tool say only 900max,psi

i desire to free up oil for injection control, but if the fault is the icp or boost control as it is a 2003...
this it seems falls under the old leaded heavier oil supplement area, but i hate to see what it could do to modern O rings.
But i guess with a few oil changes immediately with some flush and additives may free up the hpop and icp and ?vgt

i am 3hours away from any garage that can do anything, and 8 hours from a major center

any and all comments will be greatly appreciated

thanks!

 

can carbon and soot sit in the hpop

does oil effect injectors greatly (ie oil flush first, then additives?)

 

Have you checked FICM voltages? https://www.ford-trucks.com/forums/8...procedure.html

 

Sounds better than flushing the hpop system to me. Them inj. get expensive.

 

ficm 100% sync
logic 95%
main 48

Injector control pressure 20%
desired 20%
volts 25% or 1.15
injector control pressure reg 30%

mass fuel desired 10@1500 or 8%

all these show not enough fuel pressure, but i am not a AutoEnginuity/Ford tech and am just guessing at what they mean


thanks

 

and no change
