I know I went balls out when I did away with my EGR system. I had the intake manifold off, and split upper and lower. I was cleaning the thing out, and decided to get rid of the EGR. I pulled the four allen type plugs out of the underside of the runners at the plenum on the lower portion, where the exhaust gas plumbs through the manifold. Once the gases enter the valve, they pass through a long tubular passage in the manifold; the four plugs cross-sect the passage at the runners, where the gases then spills into the individual runners. After pulling the plugs, I pumped each of the four areas with high heat silicone sealant, and filled the primary passage, as well; then I reinstalled the plugs. After wiping the excess silicone away from the area inside the manifold where the holes are, I let it cure up to a solid state. No extra hardware, and no EGR components left over. I didn't have to worry about the exhaust side hook-up, because the manifold was swapped for a T3 turbo manifold that has no provision for EGR piping. The vacuum system was redone entirely to accomodate the new turbo equipment, but the solenoid is something I still need to deal with. I simply unplugged it, hoping that I could track down a way to resister the plug, and fool the computer into thinking the system was in tack and operating as normal. No such luck, so far. Seems to run alright without, but I have a nice little SES light on, now. Oh, well; just one of many issues.
