engine ticking sound
Found source of ticking. Engine was running fine before and after accident. Dropped pan to inspect and found this. Installing new cam gear. I am sure it was close to complete failure

Re: engine ticking sound
Great job! Sharing what you find and what you did to repair is so much help to help diagnose are own problems with our cars

Re: engine ticking sound
When I first heard the ticking noise I thought it might be a tappet but the sound was very faint. Put a stethoscope on running engine and found noise was to the front of the engine. Since I had pulled the engine to do the accident repair decided to pull the pan to check out the engine inside as it had not been touched in over 25 years. Amazed as to how clean it was but the teeth missing from the timing gear was very obvious and explained the light ticking I would occasionally hear

Re: engine ticking sound
Methinks that the problem is the binding agent in the composition gears fails.

Re: engine ticking sound
I could give you my opinion but could not say all is fact. As for the fiber gear the big benefit is it is quiet. The aluminum gear has a whine to it. The bronze gear is a little quieter but cost is high. The fiber gear comes in two flavors a compressed fiber and a laminated fiber. From my research the pressed fiber is more prone to failure and I went to the laminated. There is also a fiber gear outer mated to a steel center which has a history of gear part getting loose on the steel center. I am not positive but the timing gear currently on appears to be the compressed fiber gear.

Re: engine ticking sound
I replaced the fiber gear in my A's engine w/an aluminum one and don't notice any whine when it's running.

Re: engine ticking sound
I would think you have a point as to how the two gears mate up and the amount of tooth contact
