Tech, Sorry I was away from this post for a while. As I recall it was predominently silver, and is size from something like .015 accross to graphite looking film. I would accept off colr because it means little. But when there's gunk bigger than a fuel filter will catch, that to me spells trouble with small air bleeds and passages to get thru.

Out of curiousity... What excatly is the wet flow testing process? What fluid is run? Why would there be any solids in it? What determines what passes and what doesnt? It seems with the repeated processes to find issues you guys should have warehouses full of product to fix BEFORE shipping. Or is this a 5% testing type situation where not every part is tested?

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
