| driver side O2 sensor and follow the exhaust up a bit, you'll see the pipe that runs to the EGR valve. Go to 3rd photo from bottom - rear pix of engine: [ http://www.z32photoguide.com/emissions.html ] You may not find it very easy to cut/remove that pipe from the top of the engine? As long as your EGR valve isn't leaking/seals well and the vacuum line is removed from it - all should be good (valve is closed). This whole job is easier to do with the tranny dropped or the engine out of the car.
