Check the hard lines between the banjo bolt, switch over valve and ALDA. I did some work on my car and ended up snapping one of the hardlines. They have since been replaced. Also check the rubber connectors on the switchover valve. I had one rupture while on the highway. Sudden loss of turbo boost is not good while trying to get on the interstate.
