Vibrating plastic-like sound in the engine

plastic-like vibrating sound in the engine bay.. I turn off/On the engine and the weird sound is gone.

Hi Scotty!!

As you can hear there is something plastic-like vibrating sound object .. I don't know if it came inside the engine or just somewhere else. The car has 20k mileage in the odometer..

sounds like a bearing, remove all fan belts,. pray noise goes away. if so, find out which pulley has bad bearings by spinning em

okay I'll do that.. What if the sound doesn't go away? what could be the possible problem?

@ScottyKilmer I figured it out the noise is coming from this plastic

inside the plastic is the engine cam. Pray it's just a worn out timing belt or timing chain, and not a breaking down cam. Have a mechanic take the cover off and see what's breaking inside

@ScottyKilmer any reason at all why a timing belt or a cam would go bad this early for a 20k mileage engine? I change my oil regularly every 10k with 5w30. in fact I had a change oil few days ago.
