I used to have a whistle from turbo when giving the old Furby some wellie.

Now it seems quite quiet now, without any sound from the turbo.

Do see colourless smoke from tail-pipe (looking into my rear-view mirror), even under moderate acceleration, with no loss to power or engine oil loss.

Perhaps all that oil misty oily stuff has clogged-up the hole that whistled??

Good thing in a way, the wife doesn't know through sound/whistle I am pedal to the metal. LOL

Open to all, if good or bad sign.

I think the whistle pipe is blocked with cheese, but im no mechanic

prob the weather buddy lol

Found the culprit with the loss of my whistle (LOL) after making a rare visit under the bonnet.

The top inter-cooler pipe had come almost away from it's 'C' clip fitting to another pipe.

After cleaning the oil away from where it was escaping I refitted the pipe.

There was a noticeable difference in throttle response, as I earlier stated no difference to performance.

Slow decline of power must have happening so not noticeable.
