<VV> Timing Gear ?

[Roger Gault]

I drove for years with one cam gear tooth essentially missing.  No problem.
If you had enough missing teeth to skip, it would be making obscene noises
and bending valves by now.  The gear can slip on the hub if the key fails
and the press goes away (like a cracked hub - been there), but once it
starts, I'd expect it to rapidly fail completely.

In any case, your timing change CANNOT be associated with the cam.  The
distributor is crank driven.  Unless you have two problems, like a bad cam
system and a slipped harmonic balancer, you have some sort of distributor
problem.  Hopefully it just turned some because it was loose.  I suppose
there could be something slipping inside, but I doubt it.  I think
everything is pinned.

Retime it and see what happens.

Roger
