6.0 Died at stop light

I would ensure your IPR valve is plugged in. It is on the HPOP cover plate under the turbo in the rear. If so you may have an IPR wiring issue or possibly a problem with the IPR. The 132B is related to turbo performance and updating the VGT solenoid with a learn procedure. Check all exhaust connections at the turbo and make sure you don't have a crack in the flex. If all that checks out it may be the VGT solenoid.

OK, so far I’ve gathered that I need to pull the EGR valve and make sure it’s clean and free of carbon deposits.

And maybe take the turbo apart for inspection; check the VGT solenoid and possibly a faulty IPR valve.

And I need the check the exhaust connections at the turbo.


Well besides the EGR valve (pulling and cleaning)... I have no clue what to do with the rest of it. I've never had the turbo off and have no knowledge of how it supposed to look inside once I got it apart. What is the VGT solenoid? where is it and how do I check it? What is the IPR valve and how do I know if it's vaulty and can it be repaired?

I have this scenario playing in my head that I pull something off of and it’s completely caked in carbon and I have to chip away the carbon from the part. What other things could I check for any kind of carbons (or other) build up?

OK, guys this has been an f-ing nightmare. The last 2 months have changed the way I look at the 6.0. Here’s what I have done. My truck decided it wanted to start leaking oil. Well it just so happened that it started to do this on a 1500mi trip in bumb-fked W.V. I had to stop and have it fixed. I say oil leak but I could easily say a gusher. When I finally stopped it had oil dripping from the engine to the rear bumper. The mud terrains had picked up oil and slung it all over the tail gate as well as the entire sides of my truck. So the Ford dealer near Morgantown W.V. bent me over and didn’t use any lube. They charged me $950 to replace something that they called the “ICP sensor & harness”. Then I left that dealership and about an hour later the degas bottle started to leak from the seam. And the Air filter light came on too. I looked and the filter minder was broke off. So, now I’m in N.E. Penn and I took the truck to yet another Ford dealership for repairs. They changed the oil and fuel filters. Replaced the filter minder, degas bottle and cap. Pulled the EGR and inspected & cleaned it. SO… The truck is back to running as it should.

BUT, I’m still having the turbo spooling in a strange way. The Ford tech stated that he was not sure why it was doing this so maybe one of the 6.0 wizards can help. At idle, this is what happens. This happens when cold or warm but more notable when warm. You can hear the turbo whistle thru the exhaust and hear it well. Just a few minutes go by and the whistle goes away and the “popping” noise is audible from the air filter area. A few more minutes and something happens and the popping from the air filter area goes away and the whistle comes back to the exhaust. Just back and forth like that. Kind of like the turbo is working for a few minutes and then it’s not, and that’s when you can hear the popping from the air filter area. Then the turbo kicks back in. I DON’T KNOW……. PLEASE help- Any information that might be useful will be greatly appreciated.

Any help guys?

I'm gonna say something with the VGT solenoid. Not working right and it's telling it to engage, then disengage, back and forth. When you floor it does it blow black smoke or not?

[Code03]

When I floor it...it gives a puff of black smoke and then it dies down to no smoke at all...???

[jesilvas]

Ok so the vanes in there aren't stuck obviously. And the solenoid must be working. But maybe not ALL the time.
Can't think of what the popping is.

[Code03]

Yeah that's what the Ford tech at the shop was thinking too. He performed some sort of turbo test and it passed. It's strange. It's like the turbo kicks out and the popping that's audible from the intake tube is there. Then the turbo kicks in and the popping is gone and the whistle is back...

[jesilvas]

It's gotta be something with the turbo. Other than that I don't have a clue about the 6.0s.

The turbo is actually incredibly easy to inspect and repair believe it or not. Try this site
