[Healeys] Steel ball??

[Rich C]

Hello all,

I am going through the complete rebuilding of a '56 BN2 four cylinder engine.
Everything was removed from the block for cleaning, etc. While at the machine
shop undergoing cleaning, a 1/" diameter precision steel ball came out of the
block from somewhere!

I have searched the manuals and Parts Lists for a listing fo this ball and can
find nothing.

Clues anybody??
