<VV> VirtualVairs Digest, Vol 132, Issue 7

[shortle]

Lon, that is a concerning topic. And then what is the answer? NOS oil coolers? Aftermarket oil coolers? Clean oil coolers (are they even out there)?
Joel, my suggestions were both real as you know. If you say "impossible", then what is it, where did it come from, and how did it get there?

>I'm working on a 37k mile '66.  I took the oil cooler off to clean it and it had some chunks of what looks like hard rubber inside it.  They were roughly 3/16-1/4" square in size but they clearly weren't made that way.  Where could they have come from?  I guess I'm going to have to tear the engine down to get it all out assuming that there is more inside.  The engine sounds tight but the oil pressure light comes on at low idle when hot.
