I'm not liking where this is going. I'd remove the balancer and run it. You might get a little oil splash past the seal but I honestly don't see how it could be the balancer. I'm beginning to fear its more dastardly, like a main or rod bearing or thrust bearing on the cam. Trouble is I don't think you can get the balancer off.

Dear Bill and Asa, et al,
Test drive without the AC belt still showed noise. While
the engine was still warm, I removed the alternator belt. To my
surprise, the chirpy noise is still there. The garden hose stethoscope
seemed to show that it was maximal within the bowl of the crank
pulley. Hmmm??? No noise from the oil pan nor water pump
(obviously).
Next, I removed the crank pulley and the noise is still
chirping away. I checked again that the balancer isn't hitting
anything on its backside and a wire hanger feeler shows nothing between
the back of the balancer and the front cover or oil pan.
Next, I could only imagine that I had somehow not torque the
balancer bolt well and that it was loose. Sorry, it is tight and I am
sure that it has a dose of anti seize and the correct torque.
The balancer is a BHJ and is about nine years old with about
10k miles. It looks good. It was recently out and reinstalled last
year before the Houston Rally. No noise was noticed until afterwards
while driving "normally" in town, etc. Sounded like a belt, but it
isn't all belt noise.
I suppose the next step would be to loosen the balancer
bolt, again apply a touch of antiseize if it looks like it needs it and
then retorque.
Warmest regards, Chuck Engles

Charles, I went thhrough this with a corvette it turned out to be a
loose harmonic balancer bolt. Big one that goes in the end of crank.
