It seems to me that taking off the EGR valve and the football
eliminator pipe would make access much easier. Are these necessary
for access, or just a convenience for getting the turbo out? I am
going to start on this tomorrow.
Oil feed line is on top, under the EGR assembly. You will probably
need to also remove the 10 mm screw that holds the line to the
bracket, and possibly the fitting on the block as well. Not a big
deal.
The exhaust is connected via some accordioned stainless parts with
strap clamps, easy to manage.
I'm guessing your oil consumption will go way down with a new one.

Is there any way to check the drain without taking the drain or the
turbo off? My guess is not. I can't imagine the drain getting
plugged when M1 is in the engine.
I am inclined to order a turbo cartridge and just change it. If
the drain is plugged, I could clean and replace and keep the
cartridge on a shelf.
Where does the oil feed line come in?
What other parts are needed or should be replaced when replacing the turbo?
Is it necessary to take off the exhaust manifold to take out the turbo?
The ********* forum had a post where someone said taking off the
cranckase vent hose decreased pressure in the crankcase and stopped
oil leaking into the turbo. Sounds fishy to me on a 603.
Since it is now functional, I am inclined to leave it alone until I
have all parts in hand. If I tear into it, it might be weeks or
months until it gets finished because of the distance involved.
Parts needed:
2 or more drain tube o-rings
2 oil drain gaskets
EGR block kit. (have that at home but forgot to bring it.)
Whatever it takes to insure the oil feed is reliable...(? gaskets?
hose? new steel line?)
Turbo cartridge kit. (should include necessary parts to change)
It is wasting probably 3-4 quarts of oil a week currently. I need
to either order parts in the morning or postpone the mess until
another trip. No trip is on the horizon until November.
1987 300SDL is the subject.

From no responses, I gather nobody else has had a turbo failure.
Is that right?
Is it correct that any oil in the compressor is conclusive
evidence of seal failure?
...or a plugged drain line. If you plug the drain and feed it oil
under pressure, the oil will get into the turbine/compressor
housings.
I'm pretty sure they don't have contact seals on the shaft, but if
the bearings wore out and had radial slop the labyrinth "seals"
would get chewed too and might let oil into the compressor section.
