First time diesel blue smoke and weird whine or loud suction sound

Hi guys I'm hoping I could get a little advice. I'm a first time diesel owner and I just bought a late model 94 f250 7.3 powerstroke. It has a lot of kms but is in very nice running condition. Thing is I never got to hear or drive it from a cold start. I literally picked it up yesterday. Anywho it was about -5c last night and I started the truck in the late morning and it started great runs smooth but puffs quiet a bit of blue smoke. So I'm thinking no big deal its a diesel an diesels smoke when cold I'm told. So I let it warm up for about 15 mins and headed out as I got up to speed and dropped rpm to about 1500 I heard this loud whistle/whine type sound coming from what sounds to me like the turbo. It only does it when deceling at about 1500. Once I'm back on the gas it gives a sound like a release of air and its good. Once it warmed up completely it goes away it also seemed like it lacked power until it warmed up. Is this normal for diesels or should I be looking into fixing/replacing something? Thanks for any advice and help. The truck has 400000km.

The blue smoke is nothing to be concerned about both my 94.5 and my 97 do that as well as have a diesel rich stink to them. I should mention that the 97 has 3k miles on full overhaul with injectors and all. The noise you are hearing is the exhaust back pressure valve it is supposed to do that to aid in warm up. Yes you will experience a lack of power when it closes. You should have nothing to worry about though.
