Probably the "best" way to repair the block is to use an epoxy and
just fill the cavity. You will not get it clean enough to weld without
completely disassembling it and you also have the danger of fire. You
would also get slag in from the welding. Even though you may have some
of the broken bolt exposed it won't help much. The only thing you can
try is to heat it up to cherry red, let it cool, and try with a
vise-grip. After it breaks off you will have to drill it out. Retap
all the holes and check the threads, you may have to retap and
heli-coil some of the others, sometimes when the bolts come out they
remove the aluminum threads as they unscrew. In that case you will
never be able to properly tighten up the parts to the necessary
clamping pressure. Use never-seize on all the threads as you
reassemble. The block is salvageable, you do not need to replace it,
it can be repaired. I would, after a proper repair, do an oil change
and oil filter. The sand you found is what is left after you evaporate
anti-freeze, it is part of the additive package, mostly for sealing
small leaks. The anti-freeze collects in the recesses and boils off so
you never see the leaks. You should probably also drain, flush, and
replace with fresh anti-freeze. The old stuff may have gone bad and is
corrosive. Especially if it is over 4 years old. If you do weld it the
way to go is to make a small plate and weld it in. Trying to weld the
hole shut will not be easy, the metal is thin and corroded where the
hole is. Maybe just epoxy the plate in near the top and leave it at that.
