Since the damage was caused by no oil, there was no oil to carry contamination back to the oil pan. All other oil was pumped overboard before it even had a chance to reach the damaged areas (which, if it had, there would be no damaged areas). What may be much more telling, would be the oil you put in the engine when you restarted before teardown. That oil would be pumped through all the damaged areas and would carry contaminants away. Do you have any of that oil available for analysis? How much $ is an analysis? Todd (datalog this!) I believe that routine oil analysis can probably be of some value as far as trends might go, but I'm extremely under whelmed by the results of this test. It just seems to me that something should have been screaming "damage", but clearly it isn't.
