Hi Pete. The usual vacuum pipe to be missed altogether is the one from the gearbox (usually white) which hides away under the air intake ducting and connects into the top of the second inlet manifold branch from the rear.

A disconnected vacuum pipe will give you this kind of noise, so fingers crossed it is that simple!

Hi Peter. Tried to e-mail you but it bounced back to me undeliverable?

That's correct what you say. it's a pressure regulator on the gearbox I think. Hope you can solve your problem without too much trouble, I'm having problems simply changing brake discs at the moment! We'll both enjoy a malt or three imminently I think.
Cheers, Tom.
