my "one in a million thing"...at The Glen

I had suddenly a noise from my 3B head above 4000 rpm after a high rew.
(I was listening with a stethoscope for knocking) but
it did not really sound like a hydraulic lifter.
I run plug-on-coils and 034EFI ECU and don't use the gear for distributor.
To-day I would enhance my crankcase ventilation at pulled the valve cover -
and in the corner were the tooth wheel for the distributor. Not fallen off -
no cam axel had broken.
