Tom: An easy way to check for the gear being
worn out is to rotate the crankshaft back and forth until you feel the
resistance of the cam and lifters, (they require a lot of force to turn
compared to just sliding the pistons up and down). If you can turn it more than
about 10 degrees, it will be more like 25, chances are
that the chain has slipped. Ernie and The

comatose Custom 4dr. Consensus does not seem universal though on whether
original timing gear on 63 had plastic teeth or not. If you have seen
either or both types with your own eyes on an original car, please let me know
so I can decide whether to pursue that as possible cause of my immediate
problem or look elsewhere. It is a lot of work to expose that gear and I
would hate it to be for naught. My FSM is snail-crawling from
pennsylvania to arizona; I would rather not wait for it to confirm what
many of you might know already. --Tom Everyone is raving about the
