Utilised those holes which someone had cut out in the grille and changed the oil and filter at the weekend. All went well, i was worried about the sump plug but it was fine. The oil and filter (along with the air filer aswell) were the worst I'd ever seen - probably not been changed for a long time.
Managed to fathom the way the oil filter assembly worked too, which took most of the time.
I also fitted the new door seals.
Also got a nice new silver faced MK1 speedo to go in too and some glass indiator lenses to replace the plastics that have been fitted previously.
I've been doing a bit of digging and it appears the van was originally green like the one in the photo. I quite like this, so its probably a toss up between old english white with a black roof which I originally liked, or the original green colour....
