Pics of this Saturday's dissection:
I took apart my opti, cleaned the small amount of oil in it. swapped the optical sensor with that of my spare working opti, and put it all back together cleaned. it started. then turned off and no start again.
No leak on the timing cover to the opti
I replaced these rubber o-rings on the opti shaft, as the factory service manual says to do.
Only source of leaky oil on the front cover, the water pump drive seal out the timing cover. I think small amounts land on the opti and seep their way inside. BTW the opti isn't a perfectly sealed device...
Common rotor wear. (spark is not the issue anyways, just a cool pic)
