[QUOTE=Meles;3152776]Well, for reasons I'd like to not elaborate on (my stupidity), I have need to replace a prechamber on my OM603. I successfully removed one on my junk engine, but the one with damaged threads in the current vehicle would not come out and is irreversibly damaged after the attempt.

I might be able to figure out a cheap way to get the Prechamber out if I knew more details as to what happend to the Prechamber and what Tools you were using to try to pull it out.
Also I am not sure if it is only the Prechamber itself damaged or the Head?

If only the Internal threads of the Prechamber that the normal Prechamber Puller Tool uses are stripped I have Taps that size. M22-1.5

I also have My own type of Prechamber Puller that is different from the standard one; I believe it has a longer threaded area. Meaning it might be possible to go inside and take the Tap and thread down further inside the Prechamber and install the Puller and yank it out.

Another way might be to do the above using JB Weld before the Puller is screwd into place; let that Epoxy cure and attempt to yank it out.

Could you post a pic of the buggered part?
