[alfa] Spica noise

[Bob <Bob@xxxxxxxxxxxxxxxxx>]

I had the same howl on a fresh HP rebuilt pump from Ingram. It was only 
at idle and was more prevalent when engine was warm.
I sent the pump in and he could not reproduce the sound. Perhaps because 
it does not get the extra heat the engine provides? Anyway, he said not 
to worry the pump is fine,,, so, I was able to set the idle higher than 
he suggests without suffering any trailing throttle back firing. This 
greatly minimized the occurrence on this application.

I'm detecting a noise coming from my Spica pump. It's kind of a howling 
noise only at idle. I can hear it with the engine running and can 
isolate it to the rear section of the pump with my stethoscope. Anyone 
want to guess? Oil level is not rising. Car is running well.
