Bill - I guess you have checked the easy stuff. O-rings on the oil filter bolt, proper filter, proper oil viscosity? It is also pretty easy to drop the steel portion of the oil pan to see if there is loose stuff in there that may be being sucked into and blocking the the oil pump inlet screen. Case in point, when I dropped the pan on my SD to replace the turbo return line grommet, I found some old bits of gasket, from a previous repair, stuck to the oil screen. I don't think the bearing wear is so much a factor of age as the total miles. Especially if the oil has been changed regularly.
