Other weird sounds from Tacoma engine bay

I have been observing the sound this engine makes, and I hear 2 distinct sounds in addition to the engine sound (like a sewing machine)

Please check this video I just uploaded and let me know if these sounds are normal.

1. First sound starts at 0:09 sec and stops at 0:26 secs. It re-appears again at 1:54 sec then goes away at 2:15


2. Second distinct sound (sounds like a helicopter) is obvious at 0:33 secs.

 

The first sounds like it could be a squeaky belt, but in combination with the second it could be something more serious. Or it could be nothing at all, what have you done to figure out where the sounds are coming from?

 

The second sound has a frequency that's slower then the first, like bil said the first sounds like it could be belt or pully related. The second is at a frequency similar to a cyl, exh leak ect...

 

I tried to shake the pulleys at the front, they are all tight. I recorded two long videos this morning from driver side and passenger side. The sound is louder from the passenger side and seems to be coming from inside this part:

 

sounds like a normal v6 direct injection motor to me...

 

I am aware of the V6 sound and it also sounds like an old diesel engine sometimes... did you hear the other sounds though?


New video with time stamp so you don't have to watch the long video: click the bottom left to go to youtube and skip to the time stamps

 

on my laptop speakers, it sounds the same as my '18.
