I have an 04 6.0 that was running real rough, took it to ford today they said it had multiple problems....
1) bad injectors in #2 and #5
2)injector control mod had been replaced, computer and mod were not undated to match.
3)They also said I have an exhaust in the "flex" pipe under the turbo, the mech said that it was leaking where the pipe is made to flex so it needs to be replaced. This is why my turbo lag was so bad...
I had them replace the to bad injectors and update the injector control mod problem and the truck now purrs like a kitty...no more missing and seems to run great.. The problem is I could not afford to fix the exhaust leak and my turbo lag is really bad until higher RPM's. Has anyone replaced this pipe? Whats the name of the pipe so I can purchase a new one? can an exhaust shop do it cheaper, ford wanted $1100....thank you
Dan.alger its not that hard to do the turbo has to come off and then unbolt the pipe sounds easy but the bolts on the pipe are a PIA . PartsGuyEd . com has the y pipe for 170 plus shipping under 2 bills to your house. I just did mine a couple months ago took me 2 weeks but 1 week for part and i cleaned the turbo while it was off and i am slow. You can do it in a weekend if you try.Oh would not left exhaust shop do it they could really F something up.
Yes it is the only one . My egr valve is still in place and plugged in , the egr cooler is welded, the ends where exhaust enter and exit. water still flows though it this way it looks stock. Just a cheap way of doing egr cooler delete.
The y-pipe is actually two sections with a flex in each. If it's leaking on the passenger side then all you need is the up-pipe section but I don't know if it's available from Ford separately. $1100 is ridiculous to replace it IMHO. I have a used up-pipe I'll sell for an excellent price if it's not available separately and you're interested.
No hissing, just fumes in the cab...I haven't got under the truck to see for myself this is what the mech at ford told me. I'm not sure if it is the up or the down side....just really gutless till it spools
Also what Tyler said about fumes in cab, while its parked running with heat on do you smell fumes in cab. And yes egr valve needs to be kept clean. You also might want to read the tech folder a lot of info there and just reading other peoples threads slash problems has taught me a lot.
Tyler, I just noticed in a earlier thread you had 2 injectors go and you were concerned that maybe your programmer had something to do with it. I just had to replace 2 injectors also and was curious if you have had any more issues since you put ur programmer back on? am I safe to do the same?
The Y pipe is just a PIA to do.
I did mine over the winter with a better unit from Elite Diesel.
It took me about 4 hrs.
Take the alt off and then I used these directions for replacing a turbo to get to the y pipe.
Also get the turbo o-ring kit for a dealer, it is like $20. http://www.ford-trucks.com/ford-manu...%20Removal.pdf
