here's what i know, hopefully one you smarter than me can help with the rest. i have a high pitch noise coming from passenger side of engine bay. honda tech thought it was pilot bearing. pulled tranny, noticed piloted had play in fidanza flywheel, changed flywheel and bearing. reassembled and still making high pitch noise. techs have tried screwdriver stethoscope test on various locations including distributor and no dice. after reassembly, tech did place screwdriver on middle nut, passenger side of oil pan makes noise. move one nut to rear or front and no noise??? TIA
