There is some difference of opinion here, on whether turbos are
'user-serviceable' or not.
I fall on the side of the fence
The number on the turbo will surely get you the correct part. Try the
manufacturer direct, and several diesel injection services since they
all do turbos as well. You need a cartridge (compressor and turbine
wheels, shaft, and bearing body assembled), the ends will just then
bolt on. If the
There may be a slight amount of side to side play (the turbo runs on
oil pressure suppored sleeve type bearings), but ANY axial (front to
back ) play means the bearings are shot (and so are the seals).
More to the point, it should spin fairly freely, with no tight' spots
in the rotation. If
There are no seals in the turbo like you thinking. They dont dry up and
leak from sitting. What happens is you suck something in and the fins
get damaged, and cause the shaft to then be imbalanced, which wears
things out.

So explain why the intake manifold was coated in FRESH oil when I removed the
original turbo. How does the oil get from the sloppy valve guides through a
fairly dry air filter housing to the dry turbo intake? Might I have just
gotten back to back bad turbos?

It's a hydrodynamic bearing, so without oil pressure it's not going to
behave like it does in use. I've heard some axial (in-and-out) play is
normal, but sideways play should be minimal.
yea there will be a little bit of play, the play goes away when the oil
is pressurized, the shaft rides on a film of oil. If there is alot of
play, thats a different story.

Very very likely bad bearings in the turbo causing worn seals to leak
oil into the turbo intake.
The other possibility is badly worn valve guides (or incorrectly
installed ones) -- this will cause excessive blowby up the valve stems,
atomizing the oil and carrying the mist through the mist
