Whistling on idle

As title says - just come back from London - non stop - noticed high pitch whistling on idle
No power loss, noise disapears when I rev it - thoughts?

Idle whistling

Hi DiscoDunc,

you mentioned your idle whistle was because of rh exhaust manifold and gasket? Is it possible to do this myself of do i need to take it in? Someone mentioned it is a body off job?

regards

Renier
