Hi all,

Was attempting to replace a glowplug the other day and sheared the plug off at the top, just below the nut section but protruding out of the head.

We've determined the best way to get it free is weld some stainless nuts to the top, the body is stainless (TIG as it's stainless).

Basically if this isn't successful then the extra material we've added to body of the plug will make it easier if we have to resort to easy thread stud extractors, the body is quite thin and we're concerned about it splitting.

The question is do we need to disconnect any ECU's etc before welding?

Basically want to avoid taking the head off if possible or blowing anything expensive up in the process!

I thik you'll find it's actually a really shyte aluminium, which is why they shear off.
If you're lucky then you'll be able to do it with an eazi out (get the engine warm first), otherwise it's a head off job

Or if it's not leaking save your self a lot of grief and ignore it the car will start fine on 3.

I'd go with Ralph, there are specialist extraction kits available see http://cgi.ebay.co.uk/Sykes-Pickavant-Diesel-Glow-Plug-Removal-Kit-M10x1-0-/190301363242
might be worth ringing the diesel specialists in your area to see if anyone has such a tool. Best.
