I am no professional and will not say that "yes" it is completely normal. What I will tell you, is that everything you described is EXACTLY what mine looked like. I had the exact same scenario happen to me and did what you did, cleaned it, put it in, drove it, had to pull it out and clean it again. The second time I just welded the valve closed, unplugged the egr valve and the truck has never ran better since I have owned it. I too don't have the $$$ to do the delete, and after talking to the emission guy where I live, was informed that they specifically look for the egr cooler and if it is not there it fails right away. You can find an egr cooler block off plate, that way the cooler still looks like it is there and functioning.
