Need help with this noise at high rpm Just got this car on the 19th and it's making this noise around 4500rpm through 6000 I added the video don't know if the video works

Sounds like detonation to me.
You running premium gas? Can you get your car hooked up to hptuners or on a dyno or something?
This is likely from oil ingestion in intake from the PCV system.
