You have two things going on:

- IMS bearing is beginning to go south

The water pump is the rumbling part of the sound, the IMS is the whirring sound.. I disconnected the serpentine belt after I used a stethoscope to listen to the water pump housing and hearing a rumbling sound... With that disconnected the rumble was gone but the whirring sound was more defined.

The IMS flange is leaking also.. You also have a pair of leaky cam covers and a few cracked coil packs along with at least one bad chain tensioner.

I'll go a little further in the morning, but a few hours this afternoon has proven that it's repairable.
I like the prognosis so far! Good news Jake. great detective work. Yimmy, I'm glad you're excited. Hopefully you're not one of those folks that like to watch horror movies with a bag of popcorn at your side
Technically, solving a problem systematically is an engineers' dream, and Jake , you appear to be in your element. I looking forward to the end of the story.
