The crankcase breather tube and pvc valve were replaced today. A CEL came on and the local AutoZone scanned it and used their computer to diagnose it as a problem with the crankcase breather hose but they didn't have the part. After a little YouTube search, I saw this part and was able to get one through O'Reilly's and decided to replace the pvc valve at the same time.
Update 11/12/22: The CEL hasn't come on again. Perhaps I found the right thing to fix.
