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.

 

thank you, I haven't personally looked yet but it is a y pipe? is it the only flex pipe off the turbo?

Also on ur mods you state you have a welded egr cooler, did you unplug ur egr and what did you weld up? Thanks, new to the diesel and trying to learn all that I can so I can improve mine....

 

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.

 

first, I truely thank you for your advice and help........

Now, I have another question for ya
Do you pull your egr valve and clean? and how do you feel about just unpluging? Is this something I should be doing because I never have....

 

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.

 

Where I work we have 2 04's in our fleet of trucks.

Both of them have the same exact turbo lag problem.

But after they spool up they take off.

Are there any noticeable symptoms of the up pipe being cracked besides turbo lag..diesel fumes in cab? Any hissing?

 

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

 

I know what you mean, they charged me $1400 to replace 2 injectors thats is why I am on here looking for help.....

 

It's really not a bad job to attempt yourself of your comfortable working on things.

Probably should only take you a day. IMHO.

Take the turbo out, remove the clamps to the egr cooler, take the 4 13mm nuts holding the up pipe to the manifolds off and it should slide right up and out.

 

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.

Seems to me the junkyard would be your best bet.

 

Junk yard is not the place for this Y pipe needs to be new item
