Yeah, I suppose that the pin is engineered to sheer at a certain level of resistance. Hmmmmm....
The distributor shaft gear looks fine, no apparent damage.
BTW I have a melling hi-volume
oil pump, I wonder if the hi-vol version of the pump creates more resistance? Also, I am running Castrol 20w50 synth
oil.
One peculiarity of my engine build is that the
oil temp has always been on the high side, especially when in the higher RPM range. like 250 F to 275 F. Water temp is very cool, around 150 F to 180 F.
