It's not insult to injury. It depend the owner the car and their goals. If the goal is to have a stock oem SC, I agree. Fix the egr. If you want a turbo'd car with power and want to take care of it, for god sakes, pull it.
I also have to state, I had the whip out for an extended period last night. The rebuild is good, but I have boost issues. Mainly, not enough and lack of control, but I can elaborate in my under the knife thread. And my check engine light is coming on and off, due to, the egr plates I believe. Might run codes today depending on how far I get on my checklist. I'll update.
But my other point is, our cars are getting up there in age. These are mechanical components with hot gasses, fuel, oil and all sorts of weather on them. Just because the egr fails does not mean the previous owner did a bad job or the car is in bad shape. You have options on how to deal with it. Do any of them correctly and a successful resolution is to be had.
