Thanks Lynn, I was thinking about protecting an oil cooler, when it is painfully obvious that is more important to protect the engine. 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. Building oil coolers is a messy business and they are very diffcult to get clean. So the one thing you wouldn't want to do would be to have cars coming back for engines because another one of your coolers gave up a chunk of this or that. And in any case once you blow an engine there will 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 been 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. Lynn E.
