250 D question

250 D with almost 320 000 km, and I decided to change fuel injectors, because everybody said it is the last moment
A mechanist said injectors are in good condition, but engine
compression is very low???
1 cylinder     23 bar 2- 5 cylinders     25bar
Is it possible, do you have some similar experience??
