It depends upon how permanent you mean and if you can heat the parts for disassembly if needed.
If it's really permanent, I have used a lot of Loctite 680 for larger threaded connections in critical applications, it hasn't failed yet. But assembly does require heating the threads until the adhesive lets go.
Prep is important, make sure the surfaces are clean, and if it's not ferrous metal there's an activator Henkel recommends, the instructions are on the website.

Assuming it is on a rotating shaft just stake it, pin, wire or something like that.
Permanent? Hard to beat a 7018.
I just use brake kleen brake cleaner to remove oils. Is that good enough?
That should be fine. Just make sure it's good and dry before you put the loctite on. Loctite has a primer that works good. The green shaft retaining compound works good, too.
Clean the area with brake cleaner or alcohol (Mass airflow sensor spray) and let it dry Then use the Loctite 680 which needs to get almost red hot to break the bond as said above, it truly is strong stuff! Used a lot of it and the steel would break before the Loctite. The red 272 is ok but for that big of threads because it's to thin
