James,
It is a fairly simple proposition to remove the gear from the cam to check for a sheared key. Release tension on the timing chain by removing the tensioner. This will give you an opportunity to check the condition of the tensioner and the spring inside. The upper chain guide is held on with one bolt and a pin that must be pulled. A bolt of the correct thread with a stack of washers, sockets, spacers, etc. does the job nicely. Once the guide is off and the tensioner removed tap gently on the back of the cam gear towards the front of the car. It should slide forward with little effort. Keep tension on the timing chain with a bungee cord from above or a piece of wire slid though the links from underneath. I don't think a new chain would come with a new cam gear key but ordering one should be no problem. BTW, thanks for the taillight sockets! Got them installed. I would like to send you at least the postage fee but I cannot read the Street # in your address. Please provide. Thanks, RT
