should I throw out my foundation and get a new one? it appears

this is some kind of 1/2" skim coat over a section of the 8" block. there's a section where it's shifting.along side the mortar joints where there is no coat, and I can see a little bit of light through the crack.

other than the slight shifting it seems structurally sound. i put in new glass block windows and I hope it chills the.fuck out.

without context, that doesn't mean a whole lot

foundations will crack, that is a guarantee....where and how much are the important part

where is the light coming from?

There are companies that do nothing but foundation crack repair and remediation.
They have the tools, materials and Know-How to do the job right without blowing out a foundation.

Look up one of those companies in your area, consider it money well spent as you do NOT want to fuck up your foundation with shitty little DIY "fixes" like the one pictures that has failed.

See if a local company has the ability to inject expanding hydraulic mortar into the cracks as the most "economical" fix.

Cracks in CMU walls happen due to foundation shifting, but it's usually not a big deal except for if the crack is below grade and water can get in.

If you can see light through the crack that means it is above grade, in which case it doesn't really matter. Just chip off any loose material and silicone the crack.
