Hey guys! once again i need some experienced help. I have my timing chain cover off and left side valve cover off, rattling seemed to be coming from primary chain, the left side cam cassette looks to be in good shape and it does have a somewhat rigid metal backing on it. Does this metal backing mean that it is the updated version? if not is there a way i can tell weather its been updated or not. I was already informed from ya all that if its not an updated cassette to replace it, but if it is possible that its already been replaced i'd sure hate to do it if I don't have to. the engine has about 130,000 miles on it so either its updated or its a ticking time bomb! thanks once again guys your info is much appreciated!
