OK, since were drilling in the threaded blind hole, and accidentally made it a through hole, the easiest fix would be to continue what your were going to do to repair the threads--I would use a threadsert if there's enough meat around the hole, helicoil with epoxy (to aid sealing)if there is not. Then insert a 1/4" stud, WITH epoxy or thread sealant. call it done

if i tap it complete and screw a stud in it with some type of sealant will the water make it up and of stud,thanks
No thats what the sealant is for. Now some sealants are better than others. Epoxy will seal great (make sure to run a solvent--like laquer thinner) q-tip through the threads to degrease first)but its a pretty permanent installation. Teflon sealants--tape or compound, permatex etc. I would stay away from RTV for threads (because if the threads are disturbed after intial cure they can lose their seal)

Your fix will work. I had water leaking around a valve cover bolt on a 440 restoration job. I tapped the hole a little deeper, put a set screw in with sealer on it, and that way I was able to put a bolt in it, and it never leaked water when I took the bolt back out agai8n.
