Greetings. I pulled the '95 OM606 apart to clean / pop test injectors, ream the glow plug chambers, and found #6 heat shield burned on the bottom. The prechamber was burned where the heat shield seated. I made a lapping tool from a new heat shield and lapped the seat with 400 grit sandpaper, wet. [IMG]

Burned Prechamber seating area for heat seal.
After lapping.
If you zoom in, you'll see that the seat cleaned up but the surrounding surface appears to be heat checked.
Should I use or replace? Any BTDT advice would be appreciated.
