a couple of things stand out to me .
Bottom picture : It looks like Slab walls under the Blocks has cracks and shifted . This would cause the Block joints to seperate and shift . also at top of blocks the Sill looks rotted and worn out
middle picture : shows more Footing damage and Block seperation . Not sure on the Black pipe sticking out Not a dryer vent Possibly at one time Vent for a wood stove ?
top picture : looks like the continuation of the side
guessing this caused by water and frost . also guessing there is just a crawl space and no full basement underneath ? If that is the case you are going to have to find either a structural engineer or a Foundation company that jacks up slabs and walls replacing the cracked blocks . If that is the case someone will have to have access to underneath the house to verify and foundation and check the sills
realisticlly it ain't going to get any better . Might be a $3,000.00 job or a $20,000.00 job . What is the gutter situation on the house ? Not sure what part of PA. you are in but you want to make sure any Footings / new walls are at least 4 feet into the ground .
