Hi Stephen,
Sorry to hear that.  I would guess that those shavings are bearing bits. 
What you need to do is take each rod cap off and look at the bearings.  A 
pain and a hassle and be carefull not to drop those cap nuts into the 
crankcase.  Of 
course you cant tell easily  if it is a main but odds are higher it is a 
rod.   Before pulling the caps you can 
grab each rod and push up and down on it and see if it is loose - one 
will (likely but not for sure, you need to look at them) have a lot more 
play then the others if it is bad.  When you 
did the rebuild, did you have the big ends of the connecting rods 
re-sized?  They do get egg shaped over the years, and throwing new 
bearings in to rods that are distorted will cause them to go.  It is 
something that is often not stressed enough when rebuilding but is 
important.  Machine shop here only charges 5$ a rod to do this and it is 
money well spent. I saw 2 thousandths distortion on my rods on my engine 
that lost a bearing.
