Default Re: J & M crack repair / Also Lifter use

Hello Russ: I don't come on Ford barn everyday ,just once a week when I have free time. Sorry about not getting back to you.
The way that the crack repair is done, is the threaded pins are tapered like a pipe plug and are 120 degree pitch thread. They pull each other together and the locks keep it from ever expanding again. Won't break in same spot.

To try and do it your way you need to overlap the screws by 50 percent to keep them in suspension. Irontite makes a thread sealer you could use as you install the screws. Use the smallest screws you can just big enough to fill the crack.
