<VV> Used 12 plate oil cooler - not so cool

[Stephen Upham]

	I just received my "new" used 12 plate oil cooler that had been  
chemically treated and pressure checked by the vendor.  I shook it  
and heard the distinct sound of loose debris inside.  I collected the  
debris that fell out and ran a super magnet though it.  No good, as  
the magnet now looks like it could use a shave.  Conclusion, I  
seriously doubt that any used oil cooler can be sufficiently cleaned  
to prevent this type of occurrence and now, I'm almost certain that  
this is the source of the iron debris that showed up during my  
pressure check that caused me to have to completely tear down and  
throughly clean the engine AGAIN.  I had personally cleaned that one  
by using the hot paint thinner method until the thinner ran clear  
(not a process for the faint of heart), having engine cleaner ran  
through it and blown out under pressure, using pressurized water to  
blow and reverse blow it out and then pressurized air to blow out the  
moisture.
	So... now I'm pretty sure that I need to go the after-market cooler  
route even though I would prefer the original.
	I noticed that the right coast vendor has one for sale, but I don't  
know what other options I have down this alley. I  know that I'll  
have to force air though it and so a plenum mount would be my first  
choice although I'm open to any suggestions that are located in the  
engine compartment.
