How do you remove the nut holding the wire onto the glowplug, without the wire twisting, and usually cracking right at the crimping spot? I tried jamming a screwdriver in there while turning the nut, but still some movement, and so I think I "cracked" 3 out of 4 of the wires leading to the plugs. There is electrical continuity, and the engine starts fine, but I hate the thought of having stressed the wires unnecessarily.
