Most often the answers are right in front of us, however some of us don't see them until someone points them out. -------------- Original message ---------------------- From: Lehanover@aol.com > > This is not an unusual strategy for cars that must have oil coolers.

This is not an unusual strategy for cars that must have oil coolers. Bu= ilding oil coolers is a messy business and they are very diffcult to get cle= an. So the one thing you wouldn't want to do would be to have cars coming ba= ck for engines because another one of your coolers gave up a chunk of this o= r that. And in any case once you blow an engine there will=20= be crap in the cooler and now you have to have a filter after the cooler, or= loose another engine.
 
Cooled and filtered would be the minimum. So any oil source that had be= en cooled and filtered by at least an "Inline" filter would work fine. I don= 't know if a metering feature is involved, to limit the oil flow to the gear= box, but a course filter with a magnet would be in order.
