I deleted my second OSX partition and I'm missing 161gb of space. It's not appearing on diskutil or Disk Utility. I have to keep the Untitled2 partition because it stores files I need.

The above information can be summerized in the table given below.
starting sector ending sector # of sectors identifier
--------------- ------------- ------------ ----------
~76,806 disk0s1
39,112,718 81,218,355 42,105,638 disk0s2
81,218,356 122,138,127 40,919,772 disk0s3
Total number of sectors = ~122,143,554. There are 4096 bytes per sector.
The largest block of free space occurs before disk0s2
and disk0s3
and can be approximated by the equation shown below.
(39,112,718 - 76,806) * 4096 = 159,891,095,552 bytes.

so we can be sure you just need to remove the disk0s3 container that's untitled2? I'll put up half an answer in case my comment isn't making sense.
