Green Locktite is what you use for this if I'm not mistaken.
I used it on the threaded insert on my oil drain plug and it has held for 5
or 6 oil changes so far.

 While disassembling an engine I noted that the last shade tree mechanic
 in there had used lock tite on every bolt. I'm nor disagreeing his use of
 lock tite on the case bolts but I could see that he also used it on the
 Rod Cap nuts as well.
 The Question:
 Does LOCKTITE hold up to the high temperatures inside an engine and
 provide extra holding power on something like the Rod Cap nuts?
