All:

Need a source/part number for a tool to tighten the injectors on our 300SDs.

It appears we need a 2-toothed, socket-like device. We have a slight seep at base of a couple of the injectors where they screw into engine (head).

Thanks for the info/help.

What you are looking for is the pre-chamber removal tool.

Make sure the leak is around the locking ring and not the injector thread -- if it's the thread, you need only new heat shields under the injectors. The injectors are 27mm.

Maybe you should replace the return lines first to be sure that's not what's leaking. It's very unusual for injectors themselves to leak and more unusual still for fuel to creep up between the prechamber and injector. I'd even say the latter is impossible.
