depressurizing????

OK, been searching around all morning and haven't found a definitive answer so I'm going to throw it out to you all and hope I'm just being paranoid. This is a new to me 2006 6.0L, my first diesel and I'm still learning all the new "sounds" that means something is going wrong, so bear with me...

I'm hearing what sounds to me like something depressurizing coming from the passenger side, right around where the turbo is, after I shut down the motor, only lasts for 10 seconds or so until whatever it is is completely depressurized.

It's not the degas bottle, no residue or boil over, not smelling any coolant or exhaust inside the engine compartment, no white smoke from the exhaust...

I've only had the truck a week and this is the first time I've heard this.
Normal? Bad?


EDIT: BTW EOT and ECT are in the normal operating range, ECT was at 189* and EOT slightly higher at 195*. Well within the 15* delta...

It could be your turbo spooling down as well.(but 10 seconds sounds a little long for this) I've noticed that when I first shut my truck down I can hear the turbo spinning for maybe 4 or 5 seconds. I have searched the subject here on the forum and learned that it is perfectly mormal. I figured it was normal since my truck has always done this since new. Also,relax a little. The 6.0 is not as bad as people make it out to be. Keep reading here,there's LOTS of good info and very helpful people here that are glad to help. With proper maintainance your truck will treat you well.
