This is the drill kit I used.

I will be happy to lend this out to forum members with a $700 deposit, $20/week rental fee + shipping both ways. You will receive this drill out kit complete with a slide hammer, the Time-Sert kit, the reamer, and a couple of sacrificed glow plugs to use as drill templates or hole plugs as necessary.

I will also throw in the OM606 special injector socket so you can pull your injectors and get them serviced.

Please PM me for details or to set this up.
