Use the Red Locktite and try to remove as much oil as possible. To remove the oil i suggest brake cleaner spraying into the treaded area of the lifter. If you can extend the adjuster high enough to expose the undercut threaded area that would help clean the oil from some of the lifter body threads. And this area would allow the Locktite to be applied onto those clean threads in the lifter body. Be careful to not extend to far out when you see that undercut area go maybe two revolutions more for the undercut area if your able to get the adjuster out that far.
