How do you know how much metal is ok. What started this, my turbo locked up, so I started to investigate what could of happened. I first pulled my oil filter, it was clean except the magnet had the dark gray metal cream on it, about as much that would cover the top of a nickel. the oil pan vary small metal fines smaller that a grain of salt, and silver in color would not stick to magnet. A lot of you know the way the stock oil pan is made there is a round disc of metal in the bottom of the oil pan, so you cant drain all of the oil out it. I was surprised there was a quarter of an inch left in the bottom. I have owned the car for 7 years and haven't dropped the oil pan. My oil pressure is 20 psi at hot idle and 45 driving driving 50. So what do you guys think. Is some metal ok in the pan as long as its vary small in an amount and size of particle? Thanks for all your help. Dennis
