I thought I had managed to fix the oil leaks but I am left with a slow drip of oil (couple of drops per week) from the passenger side steering rack gaiter. That's seems a bit odd as non-power steering racks are usually greased

I can probably stop the leak by refreshing the (loose) cable tie holding it onto the track-rod but that doesn't explain why there is oil in it. THe BIS manual makes no mention of oil in the rack. Can anyone shed any light?
Thanks,
Keith
