Go over the exterior siding with new siding.
Use paper (30# felt) on top of the old siding.
In the meantime finish the kitchen and caulk, tar paper anything to keep the
rain out and the moisture at bay and when time
permits reside over the old.
Remember the old siding has more than likely lead paint on it also.

We are remodeling the kitchen at my in-laws house and just getting ready to
insulate. The house is about 100 years old, and does not have any
sheathing, just siding boards nailed directly to the studs (diagonal braces
built into wall).
After 100 years, many gaps have opened up between the boards, and there are
signs that water has gotten behind the siding. Before we fill the bays with
insulation, I want to minimize the chances of water getting in.
I caulked the larger gaps (from the inside. We already painted the outside
last summer), in hopes of preventing rain from blowing in, but I'm
concerned the caulking could fail in the future.
I have a roll of 15 pound roofing felt, and was thinking of cutting strips
and stapling those into the stud bays before we insulate. I know felt was
used under siding for many years before house wraps became common, and is
still used in many areas. I realize it wouldn't be as efficient as a
complete wrap of the wall, but I'm mostly just wanting to minimize the
amount of rain that enters the wall.
Other than the labor of cutting the felt to fit around all the braces and
blocking, does this sound like a safe idea? I don't want to cause new
problems trying to solve other issues.
