Default Re: Cracked block repair

Its obviously a game of how much endurance do you have.

Larger diameter would mean getting the job done quicker - but I can see that you might easier upset a larger diameter threaded plug if you do peining. (I'm comfortable with light peining to distort the upper line of threads and add backing to a sealant.

Smaller diameter would mean more work to install, but more protection to upsetting the plug.

My thought is to have "criss-crossing" of the lines of seal. More plugs, more seals, more overlap. (think to an example where one HUGE plug seals your crack - only one line of sealant. And think to the pressure to tilt out that plug should you try to pein the edge.)

But, work is work. And this, like many aspect of mechanical restoration, is one of compromise.
