Diesel question...6.0 psd...

[broncoman6524]

Long shot...in my moms truck, when you accelerate hard, it pulls, then it sounds as if its forcing air through the a/c ducts...This is like it if the a/c is on or off.

Not sure what it is, but it pulls REAL good up to that point, then it falls on its face...

its an 04? Psd 6.0, superships, volant air intake, and 5" turbo back exhaust

w/o hearing it in person it is hard to say. I know I can hear the waste gate on mine when I let off.

Mine was making funny noises in the air ducts once, the egr cooler had cracked and the bastard was eating the coolant. How's the coolant level?

Also, what is the psi on the boost at this point?

Is this in conjuction with more black or white smoke than is usual for your truck?

hmm...i never drive it...noticed it when i went to 4wheel parts... From waht i remmber there wasnt much black smoke.

Ejr cooler? guess the coolant is plumbed into a resevoir and the ejr flows thorugh it? (shot in the dark here)

Ill go and check the coolant...

When I was working at the Ford Dealership back home I don't think that a week went by that we didn't have a 6.0L with a turbo or egr (exhaust gas recirculation) complaint.

The 6.0 uses an electronic variable vane turbo and the actuator has a nasty habit of becoming stuck. This can cause it to dump boost (could be the wind/rushing noise) and the truck to fall flat on it's face but is usually accompanied by black or white smoke.

The egr also has a tendency of getting plugged and casuing poor performance but this usually throws a code. Is the check engine light coming on at all?

Ford had a new program in the later models that helped keep the turbo actuator functioning properly. Do you know if your truck ever got this new program?

Not saying any of this is right. It was just the thoughts that crossed my mind when I read your post.

No, i couldnt tell you if it has the problem that your describing...

Wehn i get home from work tomorrow ill try and see if she lets me run it up and down the road and get a video...im sure that would help out alot.

Thanks guys!

Oh, and the coolant levels were fine.
