I just turned her over for the first time in 6 weeks and it sounded rough as shit. It also spat a load of shiny glass-like flakes everywhere. The area around the turbo is covered in it. I had the bottom half of the airbox off and had also removed 2 of the 3 turbo > downpipe bolts so there was a small gap there. Must have come from the TIP or this gap. Any ideas what they could be?
