My daughter's 1987 300D (W124) has developed a significant oil leak
during highway driving.  No significant oil loss in normal city
driving but it goes through a quart of oil in 100 miles at highway
speeds, and leaves a huge puddle of oil when she stops. She has a
pretty good mechanic in her town who took a quick peek and said it
"looks like the turbo".  She is going take it back for a closer look
but I'm somewhat skeptical about needing to replace the turbo. I
searched for posts with similar problems and found replies talking
about return line seals and separator problems, but for models (even)
older than this one. Any thoughts on what this might be and/or
anything we could point her mechanic to look
at? ....................Scott

Cylinder head gasket. --

T.G. nailed the problem - a head gasket.  It took a while to decide to
invest $1800 in a car with nearly 300K miles but it is such a great
car!   Along with a new head gasket, they surfaced the head, put in a
new water pump, glow plugs, fixed a few leaks in the injector pump,
and had it detailed.

Running like new.

Continental Imports in Gainesville, Florida did the work - a very good
shop and  I can heartily recommend them.

Thanks T.G, and all on the list for your help!
