Lead flakes sound like main bearings disintegrating. I don't know of
any
other use for lead in an aircraft engine.

The main source of lead in aircraft oil is leaded fuel. However, that
wont typically
show up as flakes.


OK, I'll play. Lead, a metal, and lead tetraethyl, a clear poisonous
liquid used in avgas to prevent combustion chamber knock, are two quite
different substances. Lead is an element, lead tetraethyl a compound.
