Well this is discouraging. What can cause 7 to 8 teeth on the distributor gear to fail within 20 min. of initial start-up? 2 teeth flat with chips and distortion extending equally to each side for about 3 teeth. Ford A351 flat tappet cam and duraspark dist. I used plenty of ARP lube during assembly. The cam gear does not seem to have any damage from a visual inspection down the hole. Is there something stupid I could have done during assembly that could cause this? Any suggestions would be greatly appreciated.
