Its normal for a VVTI engine to be noisy at start-up...they all do this.If you put the engine cover back on it will muffle the sound.

 

Some of that sounds like injector noise. When I installed my new injectors for my turbo they were noisier then my stock ones and sounded like that. With the cover on and the hood closed though I don't hear it much at all.

 

PLEASE IF ANYONE KNOWS THE PROBLEM LMK, MY CAR DOES THE EXACT SAME THING AS THIS CAR IN THIS YOUTUBE VIDEO. HL did you ever figure out exactly what the problem was? I'm having this same exact issue on my 2015 toyota corolla le with 100k . I've took it into 3 different shops with no luck, I've changed plugs, coils ,filters, oil, cleaned MAF, fuel injectors but I'm still clueless to figure out what's going on with it and it's my only vehicle so I've been driving it around for 3+ months hoping I don't destroy the motor 😭😭😫

 

I don't think that you will damage your motor. Some engines just make more noise and we notice those sounds more as time goes on. I don't notice much of anything to be concerned about listening to this video.

 

I've done 5k mobil1 oil+filter changes
And inspected valve ports recently and minimal carbon build up but coated with oil mist
