You may be thinking of topping off the similar unit on the Land Rover,
Steve. They require regular topping off as part of a comprehensive lube
job - done frequently on those cars as there are progressively more
leaks with age, wear, and rust.
We may also have topped off the idler dampers on the P6s and P4s, since
it's the same design on the same family of vehicles, but that's not such
a vivid recollection.
> I have found a spare idler damper for Albert Boasberg's 2000TC, but it

> the bushings; no sign of leaks. I noticed however, that the hydraulic
> resistance as I turned the shaft was not completely steady at first.
> Now that it has been sitting upright in the vice for a while and it
> has been exercised back and forth several times, the hydraulic action
> has smoothed out. (I take the unsteady damping to be some air mixed
> with the damping oil after turning the damper right side up.)
> I got to wondering whether the oil in the unit should be topped up and

> oil 25 years ago (!) on my grandfather's 2000TCs -- maybe I'm thinking

> What is the collective wisdom on these dampers -- should the oil be
