Spark plug thread snapped e39
Ok i think the title has summed it up.
Today i was happily replacing my spark plugs as you do, when unscrewing a spark plug, i found it came up with no thead on it.. Look down in the spark plug well, and i can see the thread is still in there.
I realise this is a major problem, but can anyone give me any advise on fixing it.
