Interesting. My rattle is pretty normal, every once in a while it will clank when I shut the car down. I'd rather take preventative action since I'm at 75k and don't have much time left until I reach 82k. I don't really want the turbo wastegates to fail after I go over 82k.
I have a friend locally that is a pro with the JB4, so maybe I can ask him.
