I have no idea what he had for an oil filter, but it is hard to blame the oil filter for a defective distributor bushing and the tiny bits of material it shed. Unless they had the factory oil filter bypass blocked and were using a non-bypass oil filter, allot of oil is going to be bypassed in various engine operating conditions. Cold starts and warm-up and any running over 3000 RPM's will bypass some oil around the filter. Generally, the finer the media and the smaller particles it filters, the more it will bypass. Simply can't get all the oil through a fine micron filter all the time. The hope is it will pick-up the particles eventually as the oil makes it through the filter in multiple passes... Problem is, as the bushing continues to fail, more and more debris is dropping into the oil. What I have learned from this very long thread is: 1. an unusual engine related failure. 2. Name brand, good reputation component at fault. 3. Problem found quickly by experienced engine builder 4. Builder has been willing to go way, way beyond normal and usual business practices to resolve the issue. 5. Engine should be back in the car soon, screaming down the street and smiles all around.
