Sounds like the block retaining wall needed several weep holes,
especially at the footing... the blocks should be staggered and spaced
2-3 inches apart so water can drain, especially since PA freezes at
least 3 feet deep, so I'd say your wall needs a foundation deeper than
the frost line. Also several of those blocks should be placed as
sleepers, set the long way into the earth for strength. Since you
haven't posted a picture I would strongly suggest you have your
retaining wall redone by an experienced mason. Right off the top I'd
say your retaining wall should be of poured and rebared concrete,
cinder blocks are the worst material one could choose for an earth
retaining wall... in your climate were it me I'd have used railroad
ties. Find a lumber yard that sells real ties, used in good condition
will cost about $20 per.... they'd last more than 50 years. You can
do the job yourself but since real ties are quite heavy (200+ lbs)
you'd need a strong helper.

I wouldn't bother removing your cinder block wall, I'd set the tie
wall right in front of it. Just be sure to use real ties, those
called landscape ties are fakes and rot too quickly.
