Its past tomorrow , did you pull the bolt and find coolant in the hole ? Put the pressure tester on without the bolt and look for the leak ?

Good that you got the leak stopped.

Hopefully the bigger issue of WHY there is coolant coming up that hole doesn't get worse.

then there is the torque aspect, I don't know how the torque value of the bolt is changed by the use of permatex vs. oil.

But as long as your happy with the result I guess that is all that really matters :
