air purging sound - coolant leak

Need advice - my 04 6.0L is making a strange sound like air purging out from the drivers side of the engine compartment. Email me at ewinthers@msn.com and I can send a video clip of the issue. It hiccups when accelerating as well as when I just release the pedal. Also the truck is using coolant - seems like it may be leaking by the reservior but its hard tell tell where? Any ideas before I break down and take it to the dealer? Thanks Eric

I replaced the intercooler and the boots- still have same problem. Getting the following codes:

Anyone have any ideas?

Turns out thats the sound of the turbo sticking. The turbo went out, left the turbine in the exhaust pipe! Coolant ok, no oil in it. All the oil got sucked out the exhaust when the turbo went.
