Hey guys, I have a serious issue with my 2004 F250 6.0. Pulling a trailer something under the hood sounded like an explosion and lost power and boost. The truck started blowing black smoke from the tail pipe. I could see no psychical damage to anything under the hood. There was absolutely no power but managed to cripple home. Does anyone have an idea of what happen.

 

Look at your CAC boots. Probably popped one off.

EDIT: In case you don't know what the CAC boots are. Look at your turbo and there is an outlet going toward the passenger side. Make sure that boot at the outlet of the turbo is secured. Follow that tube from the turbo toward your front end and down. There is a boot there too that should be secure. On the driver side is a boot below your airbox. That boot should be secure and hooked to the pipe that goes up to the intake to another boot. All these boots should be attached with hose clamps and an 11mm deep socket will be needed.

 

I checked all of them coming from the turbo and all are secured to the turbo.

 

You checked all 4 boots with a total of 8 clamps?

If the clamps are secure then you might want to check the boots themselves. The boots can rupture.

 

All of the boots were secure and no holes in none of them.

 

That exact thing happened to me when a boot popped off.

Any codes?

You might need to pull your EGR to see what it looks like and clean it. Also could have a turbo that has an issue if it is not a simple boot.

 

I new when it happened it wouldn't be simple. Since I most likely have to pull the turbo to get to the EGR would you recommend bullet proofing everything. Correct me if I'm wrong don't I have to pule the turbo, wiring harness and intake to get to the EGR?

 

Sorry, the EGR valve should be pulled. Here is a pic of the location. You can get a new seal kit from a dealer or online easily.

 

I was thinking the EGR Cooler. The valve would be simple. What do think the boom was under the hood if not a hose.

 

The boom is what caused me to think boot popping off or rupturing.

Are you getting any codes or have a way to read them?

Can you start the truck with the EGR valve harness unplugged and see what it does?

Also, start and idle the truck while looking under the hood. Maybe the intercooler cracked or gave way, which could have been the boom. Just thinking a possibility. You should be able to hear if there is air moving where it shouldn't be if that is the case.

 

I have to put all the hoses back on to see, thanks for all your help. I'll let you know what I find.

 

Did you check the plastic pipe at the intake? See if it split....

 

Its a 04. Has a metal pipe. Look at the intercooler. It likely ruptured. If you have some way to look at boost it would be obvious. If your building boost then its something else. Do you have any gauges or something of the like that can see boost? If it was a 05+ truck you could look at the dash

 

Thanks so much to all for the help. I found the issue with the truck, it blew the inter-cooler. I couldn't see it before the plastic side piece separated from the fins. Have a new one ordered and will have it running soon, a much beefier one.

Thanks again for all the help.

 

Glad you found it

Figured it had to be the CAC boots or something because of that sound you heard.
