Hi Gang -
I ended up taking my 91 300D to the local MB dealer - as in the pas they
have provided spectacular service. I had them confirm the condition of my
motor mounts - as suggested by those on the list, one MM was partially
collapsed. Fortunately, only the drivers side needs to be replaced - which
I'll do as soon as I get some parts from Rusty.
Additionally, they tell me the Injector Seals are leaking - not internal
seals but the O-Ring and copper washer that fits inside the line where it
exits the IP - so the IP doesn't need to be replaced - only the metal
injector lines need to come off and a fitting inside the IP removed from
each injector exit port. I plan to do it myself and from what little I've
seen it doesn't look too bad. Don't know how I would have found these seals
were bad!
They tell me the seals leak internally & cause the problem I described -
rough idle at idle after fully warmed up.
So it sounds like a combination of the IP seals and the MM. We'll soon
see how accurate they are. ;-)
They also told me one of my Tie Rod end seals is damaged and the grease
is gone. But they didn't try to suggest I let them do the repairs. Which I
liked. I replaced both Tie Rod Assys. last year IIRC so I was surprised to
hear a grease boot had failed. Anyway, I'll look in my records to see when
I replaced them and go from there - again - no problems.
All this is FYI in case you are experiencing similar symptoms.

Thx Pter -
Very informative - will call Rusty if I need to order them. I will
check condition to be sure. I know they are not leaking but the
measurement will tell. If I need to change them it sounds like a god idea
to soak the fasteners with some penetrating oil. A shooting friend gave
me a 1/2 quart (!!) of Kroil which should do the trick.
Thx agn for the info -

Much easier than the old ones.
Chief difficulties are access to the top bolt and dropping the lower
hexhead into the frame while installing.
Loosen top and bottom bolts -- on the diesel, the right side is a pain
since the mount is under the turbo and is only accessable from
underneath with a flex-head ratchet, and it's usually also stuck. Lower
bolts require dropping the lower sound encapsulation panel (usually one
piece on the gassers, two on the diesel, and both have to come out).
Jack engine, remove both bolts and remove heat shield and mount. New
mount will usually be somewhat taller than the old one, so jack the
engine some more. Mounts are keyed into the engine carrier. Start
bottom bolt first, then top bolt. Helps to leave some slack so you can
move then around, and it's usually easier to get both bolts started
while underneath. This is required on the W201 as you cannot access the
top bolt from above. Screw bottom bolt up lightely, lower jack, tighten
both bolts fully. Remember to put the heat shield back where it was.
On the gasser, you may have to remove the bottom bolt on the left side
and jack the engine up quite a bit to reach the top bolt, as it's under
the intake and when the mounts are really flat, it's quite difficult to
get a wrench on it, even with a 2' extension! Fairly easy to reach when
new.
Easy to check condition, too -- if there is less than 3/4 inch or so
between the bottom of the hemispherical part's lower edge and the frame,
or you find thick fluid leaking out, they are shot.
