Hello guys, I really need your opinion. I'm having this car for ~3 years for now, all were good, maintained in time, genuine parts, etc.
It is 2003 year with ~150k km on odometer.
I'm pushing hard the accel, and drive over the hills. All were good. But one day I noticed red oil lamp, I've stopped during 3 minutes (no way to stop on one way road on the hill), turned off the engine, wait 5 minutes, then turn on ignition to check oil level - it was ok. then once more after next 3 minutes - all good. Then start - no red lamp.
So, I continue my journey. It was no leakage to the floor. Even after a night of parking.
Next day I took the car to drive ~15km, I took it easily. When I come to the underground parking I noticed strange rumbling sound. I got me scary.
When I come back home (another ~15km on low RPM) I parked it, opened the hood and made a video:
Rumbling no so scared me, than ticking metallic sound of increased bearing clearance, or ... ?
What do you think it could get damaged?
My thoughts: valve lifters, bearing, no more ideas.
Highly appreciated for any idea.

More than likely your super charger clutch bearing has gone bad. Remove the front part of the engine cover, remove the super charger belt to inspect it.
It's is a relative easy replacement procedure with the right tools in less than an hour.
Search the site there are lots of write ups for it.

I just removed belt for driving without supercharger, until new bearing arrive. I was so scared of metallic ticking, I remember the same noise from my motorcycle, and in that time I was right. Hopefully, I was wrong this time.
Thank you!!

Glad you got that figured out quickly. I just saw the video and it definitely sounded S/C-related. I remember having a valve drop on my Kawasaki ZX12R... Not fun, did you change the S/C fluid? It might be worth it as you're doing the bearing.
