Fantastic Engine Noise Problem

I'm going to try to get a picture of this 12th series Packard Eight problem up because I've never seen anything like it.

In the mean time here is a symptom list:

a) Intermittent gear like rattle that sometimes sounds like a loose water pump bearing and changes to tappet like rattle.

b) Noise most prominent on valve side of motor.

c) Moves around motor from front to middle to back.

d) Testing with stethoscope excluded water pump, timing chain, and fuel pump.

e) Sometimes it's there and sometimes it isn't.

f) Non-load and non-temperature sensitive.

Good luck and congradulations to anyone who has seen something similar. I have a file of wierdo noises, but this one takes the cake.

Hint, I have included the cause within this posting.
