1974 240D W115

Recently rebuilt and reinstalled the injectors and noticed #1 is leaking/bubbling where it inserts in the prechamber, and #2 is leaking where the 2 halves of the injector seal.

I currently do not have the time and space to deal with this, but hopefully in a couple weeks I will. How much damage, if any, am I doing to my engine by continuing to drive?

Thanks!
