Since going in to the mechanic for cambelt and flywheel my car has developed a funny sound when running and on shutdown. Spoke to Mike about it yesterday who recommended checking the air intake but it doesn't seem to be that.It sounds like it's coming from the centre of the dash near the bulkhead.I have checked the large black induction pipe and can't see it hitting anything. Any ideas anyone? Hopefully this link will work.Recorded with the phone on centre of dash so sounds louder than it is.

I've found it! There is a black box on the bulkhead with lots of vacuum pipes on it, the top clip was not clipped properly and the head with all the pipes on was slightly ajar.it seems to have stopped the noise. Is this the likely culprit as I also messed about moving a few pipes etc.
