If the RTV was where it needed to be, it wouldn't have to be gooped outside ;) LOL.
The bore the seal goes into should have a very very very light coat of sealer. I've successfully used orange loctite, and all grades of rtv there. The interference fit should be enough, but sometimes they weep if the bore is scratched or damaged or the seal wasn't driven in straight.
