Okay, heres what I did tonight: Remove cover from Air Recirculation Valve. Its that round thing integrated into the compressor outlet housing on the turbo. I have no idea why they would want to remove some of the compressed intake air and feed it back to the turbo inlet but that is what this thing does. Simply disconnecting or plugging the vacuum line would disable this unit. I went a step further. There is a spring that holds this valve normally closed until vacuum is used to pull it open and dump some boost. I dropped a 5/16" nut in the bottom of the valve cover where the spring seats and reassembled the valve. I did this to provide a big increase in spring pressure holding the valve closed. Neither vacuum or a high-boost condition will open it now. Next I removed the EGR valve. Again you could simply disconnect the vacuum line or plug it and the EGR wouldn't function. I discovered that my EGR valve didn't seal completely. (yes, I put a lip-lock on the thing and blew hard..... Stop laughing please!) I made a block-off plate out of 1/16" aluminium simply by placing the EGR gasket down and tracing it. Drill two holes for the mounting bolts, cut it out with tinsnips and you are in business. Install gasket, blocking plate and then the EGR valve and the hard part is done. For good measure I traced the vacuum lines for both valves to the fender. I then "cauterized" those ends with a soldering iron to seal them and plugged 'em back in where they belong. I haven't driven the car yet as it was late but I will update after tomorrow. Even a trained eye would have great difficulty seeing that anything was wrong. Hope this helps. RT
