turbo leak

hey guys,
i have a problem on my 2000 F350 7.3L psd, when the truck gets driven for the first 5 or so minutes after cold start up, you can hear what i think sounds like turbo blow by up at the firewall,as soon as the engine warms up its gone...
if it were the waste gate it would be coninuous--- right?
has anybody had this problem?
i checked all the clamps and they seemed tight...
the truck is quite a ways from a ford dealership, so if anybody has any suggestions i would love to hear..
thanks

Is it cold out? It sounds like it's probably the exhaust backpressure valve doing it's thing.

its around frezzing... when your accelerating you can feel the engine bogging down when the noise starts, it feels like the boost is just leaking out somewhere...
i have a few of these F 350 and no other truck has done this...its quite loud

You might want to check the ebv sensor and tube for being clogged.

My 1999 PSD is doing the exact same thing, when the motor warms up it stops. I was also told to check or change the ebv valve also, DUH, can some explain where this might be located. Or what it looks like?

Thanks,
Chris

That almost surely the EBV. The electrical connector for it is dwon at the base of the turbo. Won't take but a minute to unplg it and take it for a test drive to see if it's still doing it.

It can engage whle the vehicle is in operation if the right conditions are met, a quick stab of the throttle should disable it.
