Hello Neil.
Not a problem about any interval and thanks for your news. Now I can add pictures myself thought it useful to upload these three. They all show the area of the
roof just above the B pillar (from the left side so just in front of the sliding door) where the top fits. As far as I know the seals are all original.
Be useful to see the comparison when you get your van back.
On that, I'm also interested in the injector pump leak as I may have one, too. The timeline and diagnostics is a bit complicated but I'm not encountering a leak since recuilding the primer pump so have my fingers crossed it was this rather than the injector pump. The leak was evident after short journeys but not after longer ones when everything was walm. Recently, I've only been idling and putting the van in and out of the garage to work on bits. I've also researched the seal kit I need for my van, which is this one (for a 3L engine on a 4x4 CC), https://www.ebay.co.uk/itm/153865944809?hash=item23d31ffee9:g:pOMAAMXQ~6VQ4AVy.
Interested to know more when you get your van back.
Cheers
