Hi all,
I am hoping someone can help with the following predicament I got myself into. I have a Golf MK5 1.9TDI with engine code BKC.
Vagcom through up a fault on a cylinder glow plug so I thought I would go ahead and change it (done it before so know how easy it 'should' be).
Easily got the old glow plug out. Triple checked the fit on the new glow plug but something went disastrously wrong.
Torqued up the new plug to 15nm and noticed the plug wasn't fully seated in the cylinder block. So tried turning the driver anti-clockwise so I could start again. Half way round the pressure became too much for the new plug and it broke about half a cm up from the head
. The electrode is intact, but the shaft just below the nut bit on the plug is broke, meaning the nut now turns with no force. There is no visible leakage when I start the car though...at the moment. You can see the damage just below the nut (shiny arc) in the pic below.
I hate the fact the plug is broken and am wondering if anyone else has had this problem and has successfully extracted the plug in this position without taking the whole head off?
To clarify, there is about half a cm of thread from the glow plug visible above the cylinder head, but how would I get a good bite on that to extract the plug? Would an easy out type tool work or would there be a big chance of the electrode end falling into the combustion chamber once I snap the nipple off (in order to drill). I read about a guy trying in the following thread unsuccessfully but his plug had snapped flush with the head, mine is a little proud which I hope will help a little more. http://forums.tdiclub.com/showthread.php?t=238640&highlight=glow+plug+broke
I am too scared to break the electrode off right now and try to extract the remaining plug, as there is a large possibility I will make things 10 times worse. I can see that people have had problems with stripped threads from Glow Plugs but can not see anyone that has been in my predicament. The new glow plug never got fully seated so I know there is some nice thread down below if I can just safely get the broken one out.
Anyway, please let me know your valued thoughts before I make the big decision as to what to do. Pictures of the offending plug are below. Thanks.
