Hi, Is this engine-noise un-usual? Knocking?

What is your question?

This sienna recently had an engine recalibration for a mnfr recall. Not sure if this noise was there before, but I noticed it now. While idling, I hear this 'knocking'/tapping/ticking.., Its like the noise that a ceiling fan would make youtube.com/watch?v=icQhHIzvzeE I could take it back to the dealer, but I give it 90% chance that they don't take me seriosuly. Their standard reply has been its normal, unless check engine light is on. I can hear it in the cabin, but its subtle. So I recorded this near the engine.

How long has your 2017 Toyota Sienna had this problem?

A few weeks
