air purging sound - coolant leak

[ewinthers]

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

Went to see the mechanic, he said it needed a new

intercooler

, air purging was coming out of the air filter area. Coolant leak was just a pinhole leak in the reservoir. He said it may need a new

turbo

as well. Any ideas on the

intercooler problem

and potential fixes? Thanks

Check your CAC boots for a tear or rip....Loose connections, rubbed holes.....ETC

I replaced the intercooler and the boots- still have same problem. Getting the following codes:
P0299 Turbo underboost
P0478 exhaust pressure control valve high input
P0603 Internal control mod kam error
Anyone have any ideas?
Thanks

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.
