Cross posted to .mods as I know quite a few people on there have had 306s and the like.
The glow plugs on the ZX seem to have stopped glowing. I've managed to change the third one, but all the others are behind something else - 1 and 2 are behind the injection pump, and 4 is behind what looks like some sort of oil breather apparatus. Has anyone got any idea how to get these off? I've seen mention of using swan neck spanners in posts on Google, that sounds a bit optimistic to me...
