The breather hose does have to be a specific type with a proper oil resistant lining. Air/oil mist that comes off the crankcase can attack normal rubber. > Secondly, he said the bypass valve was disconnected.

I'm not exactly sure, but if you follow all the hoses off your throttle body (should be one between 15mm and 25mm), you'll arrive at it in the end. It's black, says Bosch on it and on your car should have two large 25mm ports and one vacuum port. It should fit into the large air pipe that runs between the airbox and the turbocharger. With regard to your vacuum, hose is cheap enough to replace all the hoses under the bonnet. Take each one off in turn, cut the correct length from your new reel and fit it. Don't think about pulling them all off first, or you'll forget how they go back together. Paul 1989 900 Turbo S http://saab.go.dyndns.org/
