I know stuck Glow plugs in the 606 has been discussed endless. But here is a new one:

As the title suggests I drilled too deep when trying the extraction process. I was following the method where you tap the body of the GP so you can install a hardened bolt into the body and slide it out by tightening a nut down the bolt. But I never got that far.

When I was drilling out the center of the GP, I must have went right through the tip on the GP. I went so deep that fuel started to flow up into the Glow Plug chamber. What is behind there? Did I just completely ruin this head, thereby ruining this car?

By the way GP still stuck in there. The tap/bolt puller method didn't work for me.

Thanks in advance.
