Hi, I bought a '13 BRZ yesterday and when the engine gets warm it starts tickling, and knocking. After research, I think it could be the vacuum pump, fuel pump, valve proble or rod knocking? Some say it's normal. Does anyone have had this issue or could know what's up with it? I've posted videos on Reddit so I'll just link them below. Thanks

Warmed up after 150+km drive:

When it's cold it sounds normal to me, but strange noises when warmed up.
