[Tigers] Timing deviates - advice needed

[Thomas Witt]

>>> How many slips of that can you have before you are snapping valves?!<<<

I had the same thought. You would think finding a tooth count on te SBF cam 
gear would be easy on the internet..., but all I could find was a reference 
to 8 degrees per tooth (which equates to 45 teeth). Still if he is resetting 
the timing, having the problem reoccur and resetting the timing again that 
would be 16 degrees at the cam - if teeth are slipping. At that point I 
don't think he would get it to 'run well again' like he has. It sure sounds 
like the distributor gear is spinning on the shaft. Given the load of cold 
oil at the pump spinning off the distributor it would give reason to it 
setting correctly and then shifting again on start up - later when cold.
