Thanks for the info.
After a bit more research I found out it is the DOHC 16V M42 B18 engine
So now I know it's a timing chain ... phew!
Do these ever need changing? I assume they should be checked for tension/wear?
Yes checking them sometime is good idea. But normally they don't have to be replaced. Get's real nasty when they do break however.
They aren't terribly expensive, so changing them when it's apart for changing the guides etc when it's starting to reach high miles could be an idea.
I had a M42 with 16kmiles on it and the chain seemed fine when I took it apart to change head gasket. That is in a pretty demanding climate.
