And the sound was rhythmical not random. Would metal particles make it to the filter before the engine oil drain plug? I'll pull that tomorrow and check it out.
Thanks again for all the suggestions.

Sorry, for some reason I got into my head that the previous rebuild was DIY.
Rod bearing particulate wouldn't cling to the drain plug as they are non-ferrous.
Picking up an engine stethoscope from Sears for a few bucks might be a good investment if there's no 'glitter' in the oil filter pleats. After checking the filter, and also checking on the chain guides, that is. They are worth their weight in gold for tracking down noises. I've had three engines on my lift making scary rod knock noises, and in each case the stethoscope helped me diagnose an issue that was up in the (far less expensive) top end.
