Knocking does follow RPM’s but gets much quieter almost goes away once motor reaches 2k, loudest at 1k rpms, if i rev it up to 4K sound kinda reappears but very quietly, and once rpms drop back to idle it loud again. Currently 86k miles, never had issues with it before. Obviously I’ve parked it and not driving it for now. Out of warranty and don’t really know to many mechanics locally, anyone has ran into this issue before? Or know what could it be? I’ve added couple links to two videos I’ve made and uploaded on youtube.
