Hi, new here. I've just bought a 2006 4.2 supercharged with a blown head gasket. I have been searching around but haven't been able to find any threads on replacing the head gasket. If there are any guides on the forum or elsewhere on the internet i'd appreciate any links.

I've got a few basic questions, how hard is the job with the engine in situ? Does the whole front end need to come off to get access to the timing chains? Are these the correct tools, do I need anything else? https://www.ebay.co.uk/itm/JAGUAR-LAND-ROV...:rk:7:pf:0
