white smoke and expanding hoses may also be sign of a cracked head. block is cast iron while head is cast aluminium -- a reciepe for head wraping/cracking when cooling system is not working as it should.
So definitely inspect the head whie it is off, and keep in mind, tha the crack may be very fine. Also, crack around the "swirl chamber" are almost normal on these heads; its the cracks where coolant flows that should be of concern.
As far as the trubo goes, I don't know taht you can properly test it with car not running. However, you can check for cracked hoses, loose bolts/connections. If you remove exhaust downpipe you can try to move the turbo fins to ckeck for excessive play. But with car running, you know turbo is working if you hear a turbo whine and feel a boost in power at and over 2200 rpm.
And most likely, you will have to get new head bolts when you go to put it back. Also, use the right head gasket (1 notch, two notches, and three notches are the choices i believe). the proper head gasket is a function of the thickness of the head after it has been shaved at a machine shop. wrong gasket reduces power.
good luck.

I am new to Peugeot and diesel engines. I have no books for this fine
looking car. I was a pro VW mechanic during the 70s and early 80s. Now
I am a pro electronics tech. I prefer to read about a job before I do
the wrenching. I have a decent garage in which I am able to weld with
gas and electric and of course I am very handy with the electronics. I
am often asked for advice on various home auto repair projects to
which my first suggestion is to get the book and if possible get the
official service manuals and read them. I am not a magician, merely a
mechanic and lately I work only on our fleet of ranch vehicles. This
said, I am about to pull the head off of my Peugeot not knowing where
hoses and wires will return to nor what they do, then attempt to buy a
head gasket from I don't know where. Not my ideal way of working, and
certainly goes against everything I have preached all these years.
I have never worked on a diesel engine and certainly not a turbo
diesel. I need to understand how the Peugeot turbo works and if it is
working. I would like to test it while the head is off as this seems
like as good a time as any since it is under the manifolds. I
understand this is the place to be for Peugeot. However I haven't seen
any people talk about the nuts and bolts of these cars, aside from
some minor repair information sharing. I am completely in the dark as
I was the day I first asked if anyone had a service manual or even
knew where to go to get one. I admit I am short on cash and long on
questions. I have to start somewhere, right?
Questions I have put forward to date are: White exhaust smoke and
expanding coolant hoses are invariably signs of a blown head gasket,
where do I buy parts? Where do I look up information online? Does
Peugeot really not have a decent web presence? Sorry if I am
forgetting those who wrote back and told me of Mr. Holm, this is my
attempt to get in touch. I should call and may do so from work
tomorrow. I feel exposed not having anything going for me.
