@reachjimbo

nah mate, as i said it was a gasket leak manifold->turbo, and whilst it was a simple problem to fix, taking off and putting back the turbo to replace the gasket is a lot of labour, about $4-500 worth

[willskijza80]

yeah, was a gasket leak

That would be what they call, turbo purge. When you wind up your turbo, you will hear a high whistle, then a blow-off, where the sound dies down till you wind it up again. When you push in the clutch, like when you're coming to a stop, you might sometimes hear a crackling noise, similar to a dull backfire, that is the blow-off valve. So that sound you heard when you went to shift, is the trubo fan slowing down at a rapid pace. Its normal and necessary to function. :)

cant hear though possibly just your turbo - manifold gasket - under boost will create this "scream" type of sound. no power loss etc.
