Today did more maintenance on the Citroen DS, including:
Oil and filter change Rotate tyres Cleaned all the dirt out of the space behind the rear wings Changed the small ID style hubcaps on the rear for the correct DS type
Still a bit of work to get this car where I want it, but getting there slowly.
For future reference on the oil change:
Sump plug: 22mm Oil filter housing: 11mm Oil filter: 12mm
easiest when you use an extension on the ratchet.
