That thought crossed my mind. I use silicone grease to lube oil
filter gaskets, and putting silicone dielectric grease in our
ancient electrical connectors--my dad's Model As used the same
type--seems to help prevent some of the Lucas gremlins. I use a
silicone 'oil' where light lubrication is needed and dirt and dust
can build up (speedo cables and Bendix gears on starters come to
mind).<br clear="none">

transferring an original plate to one of their newer

dropped the oil pan on my 100 to replace the oil
pump and found numerous chunks of what seemed like
very hard black plastic distributed throughout the
sump. This was a head scratcher as I knew there
could be no plastic in the engine's interior yet
there it was. After thinking about it further I
decided that it could only have been the remains
of the rubber timing chain tensioner and sure
enough when I pulled the front cover I saw that
the tensioner was non-existent and the chain
pretty loose. I replaced the chain and
tensioner--not an easy job--and magically a
chattering sound that had been appearing at
certain rpm's disappeared, no doubt a harmonic
rattling of the loose timing chain.</div>
