If you have a loss of power at the same time as the whine, it's probably one of the hoses. Are you SURE you inspected them really well. I had a leak a while back that I couldn't see until I flexed the hose around in my hands with water running through it.
You can also have someone rev the engine while you watch with a flashlight under the hood, (or bonnet
). You'll probably be able to pinpoint the location of the noise if you're looking at it and there will be a rush of air and possibly a little mist/steam where it's coming from (assuming it's a leak). If it's the turbo, you're more likely to hear something like metal scraping...so I hope it isn't that.
