Bill,
you are quite right with nylocs - basically. But I don´t have them in my engines at this place, had to have all special spindles - Argentina B-Raps - so went for tiny o-rings in recesses at spindle ends instead. I can easily measure up all depths for recesses and countersinks in the timing cover so I can tell if that is allright for o-rings. My guess, nylocs can come in variations of sizes where the rubber seals have to go, so a no for me.
Incidentally I had to do extensions on most spindles when I finished them - had them case hardened 30 years ago and only a few years ago found out that I had them too short . I did not see that the steady plate goes on spacers and not bolted on those cast pillars directly. Well - another hour or two for trick extensions to rectify this. For bolting up the extensions I had no space for hex heads , too close to the cam gears. So an new experience with milling - ah, what´s a hexagon with twelve corners - a twelveagon ?
Today I looked at this photo and found no detail on cam spindle ends about seals there so seems I missed something in this stage.
