Timing chain service, what should I purchase and what's of main importance?

Hello, this is not a do it yourself repair! Unless you are fully equipped with tools and a shop environment, you do not want to be "trying" to do this repair. Additionally, if your timing chain jumped a few teeth, have you verified that the pistons have not been damaged from impacting the valves? When you ask "what tools do I need??" - respectfully - it is clearly beyond your abilities to successfully do this repair - if it's even possible in the first place.
