When I removed my glow plugs for replacement, one snapped off at the
element right below the thread and has stayed tightly jammed in the
cylinder head.
I have no problem starting with one plug U/S but would prefer to
remove it if there is an easy way. I have tried running the motor to
"blow it out" , didn't work. I tried getting a self tapping screw into
it but the white insulating powder in the element wont let the thread
get started, and I think it is jammed too hart to pull out that way
anyhow.
I would like to hear from anyone who has found a way to remove the
stub without removing the head.

Thanks.

I know of an engine engineer who regularly has to drill out glow plugs for
mercedes (snapping glowplugs apparently are a common problem with the 3L,
5cyl engine), he drills it so precise he can remove the thin film of the
element which is still left with a scraper, but... this is with the head
removed..and he has his machines equipped specially for this type of heads.
If things comes to the worse, there might be an engineering workshop around
your place, which can do the same.
