Would anyone care to share their experiences with the oil filled vane type shock absorbers on the 6th Series cars.
Firstly what grade of oil works best in an old shock absorber.
Has anyone come up with a practical means of overhauling these units? Alternatively is there a period correct alternative noting that they were apparently considered unsuccessful in their day.
I cleaned mine out as best I could given that they are fully sealed, then primed them with oil many years ago. I don't recall the grade of oil but they are now next to useless in damping the suspension.
