Anyone else with info/input would be greatly appreciated as well! Thanks.

The oil cooler
might leak and cause the intermix but this is usually due to a cracked head . The oil cooler is easy to remove and pressure test so that is a good first step but you'll probably find a cracked 1-3 head, with the crack running between the #1 spark plug hole and one of the #1 exhaust valve guides. You should remove the 1-3 cam cover (note: a special tool is required to hold the cams before removing the cover), clean the area between the #1 spark plug hole and the #1 exhaust valves, and check for a crack before further disassembly. It'll be easily visible after spraying the area with brake cleaner. If the crack is not found there, repeat on the 4-6 head.
