There's no need to remove the EGR. Just cut a tiny little section of sheet metal to fit between the aluminum EGR pipe and the intake manifold. Loosen 2 10mm bolts, slip sheet metal piece between, tighten bolts. The EGR is rendered completely shutdown. My EGR pipe was almost completely clogged anyway. Yes - a check engine light was always illuminated. I always thought the oil-burning problem was related to the EGR problem. No use fixing one without the other, and the only way to eliminate oil-burning was to rebuild the engine which I wasn't going to do. I brought the Prius to the dealer at 160k miles or near there to look at the problem. They didn't find a problem with the car. It was under the threshold of their max oil usage criteria. No dealer help. I was a 100% loyal Toyota customer until this happened to my Prius.
