thanks for replies but...

mine isnt a turbo model. its just a petrol n/a. automatic.
i believe the vac valves are connected by a narrow bore pipe to the brake servo, as i have blown through the pipe connecting them.

The brake servo only has one pipe from the vacuum system,,there are two pipes that go to the headlamps

As I understand it there is a thumb wheel to the right of the light switch,,and this sets the headlamp height
