Jack, I have some engines with over 40k on them now and the gears still look good. I don't think there is any rule of thumb regarding the gear. It is a good idea to check it from time to time. The only engines I have ever had problems with are the 302 and 351. Once we started burnishing the cam gear I haven't had any gear failures. A little wear is normal once the gear and cam mesh.
