Hi all. Well my D2 Vacuum leak has got worse and its affecting idle tune (a little). Its a really loud whistle and my wife told me today that the other night she could hear it clearly out the rear when following me. It sounds like its coming from the front of the valley near the alternator/air con compressor. I have tried the usual suspects (pipes hoses etc) and have sprayed CRC around for no change in revs and cannot pick it any better than that.

I think I will bite the bullet and strip off the plenum and valley and have a look and replace all the gaskets. Anything I should do while Im at it (have already replaced recently the plate and gasket under the intake and have recently done idlers and tensions on the front).

Cheers and thanks.
