Re: Timing Chain?
The car's timing and your manual are both correct, and your car does not have a timing problem.
Notice that the cam gear is twice as big as the crank gear, so it rotates at half the crank speed.
Try this.... with both gears at 12:00, put a wrench on the crankshaft and rotate the crank 360 degrees. You will see the cam gear only rotates 180 degrees, leaving the crank gear at 12:00..... and the cam gear at 6:00..... as the manual says.
What you do have is a typical problem with old nylon timing gears. Nylon is used to reduce cam chain noise, but it is weak and becomes brittle with age, hence the pieces coming off. Replace the chain and gears. You will find that virtually all replacement sets are all-steel, with no nylon to break.
