It's one of a few places that likes to attract and retain water, and then rust solid, even in well-maintained engines. I used to use antiseize on those, but now I: (1) run a bottoming tap into the hole to remove all crud (2) squirt brake cleaner into it to get it spotlessly clean and dry wire brush, run a die down, or replace the stud (4) use lots of non-hardening gasket cement in the hole and on the stud. That will keep water out. Ask me in 10 years how it's worked out :-) _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
