By glitter do you mean that you have metal shavings, metallic dust, or something similar in your oil? Sounds scary. I don't know how much, if any, residue is created upon break in, but I would be hesitant to start it up again until there was fresh oil in it. Sorry, this is a "non-answer" response to your post. You already know that you have a problem. Hopefully someone has seen something similar to this.
