Sorted as much as its going to be for the retest Mick.
I think I've done all I intend to do. I found I had a new set of spark plugs lying around and although I've done the job, before on a Clio, i decided not to bother. They are buried down some very large holes and require this tool (the long metal tube), to remove them, and then there's stuff to disconnect/remove to get at them, so rather than disturb things I didn't bother. I will have some feeler gauges somewhere but haven't seen them for years, gap supposed to be 0.9 mm.
The other thing in the pic is a good little tool for removing the oil filter, because its in the most awkward of locations matches the flutes at the end of a proper spec Clio 2 Oil filter.
