<VV> FINE particles my input?

[N2VZD at aol.com]

I have have run Deves rings , and Hastings Iron rings in many motors with  
no problems. I imagine they are broke in before the motor is put in the 
vehicle.  I run all motors at least one hour on the hydraulic table I build them 
on. All  adjustments and tweaking are done and ready to go. I then drive 
them a few  hundred miles on a day trip or two , then  change the oil and look 
 them over.
I also put very strong magnets from junk hard drives in all of my motors ,  
transmissions , and differentials to catch any fine break in particles. I 
also  use magnetic drain plugs as sort of an indicator if too much going on 
in the  wear dept.
one magnet on inside of each valve cover , one on the oil pump screen  
shield in the little recess. on top cover of differential , in pan of  
powerglides. I do not have any 4 speeds . a recheck on a couple shows the magnet  
grabbing VERY fine "mud" in each case. I bet it helps?
A guy could also put a magnet that strong on the outside of an oil filter  
to help also.

A few motors etc under my belt.
