I just changed my oil to find a few big metal pieces and a bunch of flakes in the oil. The pices looked like tiny curled up spirals but the were thick. I used a new pan so I crossed that out. The engine doesnt smoke or knock and my oil pressure gauge says it still has great pressure at idle and at speed. Also the turbo is in great shape as well. I checked the filter and there wasnt really anything in it. I didnt think to see if the metal was magnetic. Any ideas?
