I was just thinking the same. It should be possible to get a blade behind that and grab the end with pliers. The danger is whether you may damage the thread in the casting; but I would try this before attempting to cut it. A bit of a long shot but have you tried putting some pressure on the visible end to screw it in deeper? With a warm case the chances would be better. In any case, helicoils are not generally oil-tight and you will need some sort of additional seal. You might do just as well to put a suitably-sized sealing washer over the top of it.
