Its the front drivers side bolt that sticks into the cavity above the waterpump. The head should get sent in for surfacing and valve job regardless,they can check it then.
That seems like a lot of coolant in the oil for just that one bolt even if the sealant was left off but I don't know for sure because I've never had that issue. You could always try putting sealant on that bolt and run it for a bit to see if you're still getting contamination. It's bolt 11 and you need Loctite 592 or equivalent.

Next step would be to do a cylinder pressure leak test to look for a bad head gasket or a cracked head/block/piston
The jeep heads like to crack from the coolant passage to the valve cover area. Leakdown test wouldn't help in that scenario. Cracked piston for water in oil? Lol
He can fiddle with the bolt but the next step is removing the head

At least I didn't ask if a can of Bars Leaks would fix it!!
