I took my BRZ in to get the oil changed last week and alerted the head mechanic about the engine noise (crickets) and transmission rattle I experience. He just gave me a call and told me that he has parts on order to fix the engine noise issue. He explained that it is related to a plunger. Looking forward to the fix. It doesn't affect performance but is annoying. Hopefully everyone else has or will be getting this fixed through their dealerships if they have it.
