97 Question

[Showpanther]

Hey folks. I'm new to the site and like most newbys I'm probably asking an old question.
My 97 F350 makes a hissing noise in the back of the turbo when you start it. I have noticed a linkage rod under the turbo moving from right to left and back as the engine is started and that is when I here the noise. It didn't do that when I bought it and was wondering if you can tell me what to do about it or if that is normal foe 173000 miles.
Thanks

Thanks Marc
After reading the thread it reminds me that last winter when I started out cold, about the time the thermostat would be opening it will lundge and the hiss will come in and I loose all power untill I give it more fuel, then the hiss stops and I regain power.
I'm asking these questions trying to decide if I want to put a Bully Dog Chip on mine. I don't want todo anything to damage thing worse if the hiss is a problem
Thanks again

the chip should have no bad implications to your truck as far as the hiss. the hiss will still be there. the only way to get rid of it is to disconnect the valve or gut the valve all together, but the chip will not affect the hiss positivly or negativly....
