High Pitched Whistle

Hey

So recently my 57 Ford Focus 1.8 tdci started making a strange high pitched whistle type noise. It only does it when you first switch the engine on and when the revs get to about 1700rpm and the turbo starts to kick in. After you have spun the turbo up 2 or 3 times it stops and goes away until you switch the engine off and leave it for a few minutes. If you restart the engine you get the same again. It sounds like air being sucked through somewhere as opposed to anything else but i'm not sure exactly which hoses, etc could be the ones. There is no loss of power, no lights on the dash or smoke coming out the back. Any ideas or help would be great

    I would be checking the intercooler hoses and pipe for any cracks.

    Yup, sounds like an intercooler hose. Happened to me last week.

    It's quite an easy fix... I got this (http://www.ebay.co.uk/itm/121266583573) pipe and it's all good. Took me around 15 minutes to replace, as one of the screws is really hard to get to.

    Hi, I already changed the hose u linked on eBay. Anybidea which other one might be worth changing? Is it usually one of the pipes from the intercooler to the engine?
