I have a whine but only when booting it after a kickdown its so annoying

[Diamond Black Geezer]

And mine apparently went away all of yesterday, my Miss DBG was driving her all day and couldn't hear anything. Ahhh, intermittent faults, dont you just love them?!

So after lavishing attention on the old girl, there's two odd little whines/whistles appeared since the service...

Whistle - Hear it in the cabin - more so on pass side? Sounds like a Clanger in a box. Yes, a whistle, high-pitched but quiet, which rises in pitch depending on revs. My theory is it's vac related. I have changed the purge valve, and no more petrol smell on startup. Fuse pulled for SAI. The front multiram has been changed too. Nothing else vac related (that I can think of) has been changed.

Whine - Fractionally audible from interior, obvious when stood next to car. Coming from the front end. Disappears under any revs, so only occurs at idle. Pulley/ belt related? Will check for anything rubbing against the aux belt, but nothing apparent with a visual inspection last night.

Well, I'm confused! 

Something trapped under the plenum on re-assembly perhaps?

Was the purge valve visibly faulty, I get a petrol smell on startup too but can find no leaks.

It was possible that the FPR to TB pipe had been trapped under the plenum since my last disassembly, though I'm not 100% it seemed to be a bit crammed in under there. But all very nice, now. that I'm sure, I was fastidious and careful, took my time.

I know there was much debate over the purge valve on here, but there was definite difference in flow between the old and new (new one flowing much better, old one was like blowing up a baloon, you had to force it, would be hell for, say, a smoker of 20 years!) And the one-way valve seemed to work better, too, seemed like slight weeping on the old one.
