<VV> Engine knock diagnosis

[Kenneth E Pepke]

The factory used a special main bearing at the flywheel
end of the engine.  It was designed to silence a crankshaft 
noise made by a sideways movement of the crank that 
resembled a main bearing failure.  My memory on this is a
little hazy on the exact details.  Perhaps the 'hole' in the
bearing is offset .0006 towards the driver side.  Very early 
or rebuilt engines will probably not have this special bearing.

Have your drain oil analyzed to determine bearing content.
