[Vintage-race] oil cooler cleaning

[WSpohn4 at aol.com]

I can't really disagree with that, but would note that I have cleaned out  
coolers that are too expensive to lightly replace (I use some Mazda rotary  
coolers that are very large and very, very expensive unless you find a good 
one  in a wreckers) after wiping a bearing.  A combination of solventing and 
 ultrasonic cleaning gave a result that I was pretty sure was OK.  I ran a  
separate oil filter downstream of the cooler just to be sure and when I 
read the  entrails (it was a canister style with a nice Crossland felt filter 
you could  pull apart and examine) there were no particles present.

I can't  imagine any cleaning process getting the cooler clean enough that 
I would  trust it.
