How about the older rope crankshaft seals? They were grease and
graphite-impregnated seals that had to be cut to size. You would lay
one half in the proper groove, lay the crank in place over it, and
slice the excess seal at the surface of the main bearing cap joint with
a razor blade. Then do the same with the main bearing cap itself,
leaving a "little" excess. Then when tightening everything down, the
seal would be pressed onto the crank. If not tight enough the crank
seal would leak...if too tight the crank would not turn. I had a
flathead Ford that I had to push to start the first time, and the
wheels skidded until that seal gave up its grip and let the crank turn.
Yeah, today's mechanics have it made with the modern seals.

When I saw the first "Chamois" filter I was surprised to find out that
what
they were actually using was a felt. One of the properties of felt is
it
stops the flow of water while passing gasoline.
Noel, I had an old car that used felt for the crankshaft seal. This
was old-fashioned engineering but apparently common. I understand
those seals would give about a year or two of good service, so rubber
and/or silicone shaft seals must have been quite an improvement back
in the day.
