COMP Turbo Oil-Less Weird Noise

Over the weekend went on a club run through some twisties. Didn't really push it all that hard ( cause of all them normie NA 370s up in front ). Got to the meeting spot and noticed a very loud audible high pitched almost bearing like noise coming from the Turbo.

What's super weird is after shutting the car off, and immediately turning it back on 10 seconds later and about 95% of the sound was completely gone. I couldn't see any leaking from the zerk fitting, but I'll get a chance to properly go under later this week.

Any other COMP guys here ever experienced this?
