Wow, sounds like there is a really huge problem cooking up in our N55 engines. I have been so happy that I could say my motor is really reliable, now i'm getting a little worried. Because at low RPM's I'm getting a little rattle noise when the engine is warm. But it started happening right after I got my exhaust put back to stock. I was hoping it was cuz they didn't install it back correctly. You guys think I should be worried?
