hey guys im sure its been asked b4 but just a quick question

are there any guides on how to do it? like step by step? or is it just a case of ripping it apart and smashing the new ones back on? or if anyone has any tips or hints would be awesome. cheers

easiest way i would assume is to pull the engine out of car
as the head and sump and timing case cover have to
be removed

No they dont M8
With some patience and a bit of initiative, a new chain can be drawn around connected to the old one.

E is right if you are just replacing the chain
without changing the chain guides.
