If you're going to go through all the trouble of RE&RE'ng the Upper Intake....Why not install something to help prevent the EGR problem too? Try something like this: http://www.pureperformancefever.com/...roducts_id=701
As on cleaning the lower intake & such....Try a 3M Scotch-brite pad. They come in varring degrees of grit. I suggest a fine or medium grit for the lower. Chemically clean the upper though, as scratching it in ANY way will cause it to leak! Just make sure the chemicval you use doesn't warp it too. FI/Sensor safe Intake cleaner & elbow grease is your safest bet though.
