Noisy timing belt

[KeyFlo_dsm]

*2 very short videos addressing the issues included*
Hey everyone so the car's running again but I wanted to get your input on this sound coming from the timing belt/ cams area. It's persistent until I reach about 3k rpms then fades out. The belt itself still looks good. Once again however, I need to know if another mechanic is trying to hustle me. He said in order to find out where the sound is coming from, they'd have to get underneath the car and move some things around etc. Then gave me his "estimate on similar types of problems in the past" of $600+.
*Also noticed a bolt missing from the belt casing.*
I come to you once again oh wise ones!

That's the sound I remember if the timing was off a tooth or so. Its been too long...but it sounds very familiar

I've been using the car as my daily driver the past few days and the sound hasn't necessarily gotten worse; but it definitely doesn't sound good. The last thing I want is for the belt to slip.

It's hard to say what it could be. Only way to find out is to pull the cover. It does sound like something is rubbing the cover.

Would that be something I could check on myself with a couple tools or do I really need to pay a mechanic to take it apart? (My car knowledge 2/5)

it kinda sounds like the hydraulic tensioner for the tiiming belt is bad

Just watched a couple videos on hydraulic tensioners. Sounds very similar!

To me sounds like you have excess cam clearance. If so, most likely you have bad lifter(s).

To be safe....id pull it apart before your valves possibly get lovey dovey with your pistons

I hear stuff from the video but hard to pinpoint what you're talking about.

If there's been a recent timing belt job, maybe the tension was set too tight? This happened to me, took out my oil pump.
