His english is not perfect so I have to fill in some places.
Anybody ever heard of similar? Can this be done in-place or will it require head removal?

We need to know what year and model Mercedes you have? Or if you know what Engine you have.
If you have a 1982 W123 the Injector actually screws into the prechamer retaining ring. However, that is not usually where the injectors leak.
