it doesn't seem to bad. its at a very slight angle, towards the front of the engine, i say i think its misfiring but not actually sure car drives perfectly, but we changed the knackered coil packs, and the one on that spark plug was cracked, and it seemed like it was because of the angle it was attached.its not a major issue, but its just gonna cost a fair bit if it keeps cracking coils.
cheers for all the input fellas, we just really dont have the tools or equipment to do it ourselves. rather pay out 100 bucks or so rather than having to forkout for a new head/gasket/ancillarys etc.
