"you also might have another self-inflicted problem. If I were you, I would cut open my oil filter, and get a magnifying glass, and look in the pleats for brass. If it is there, time to put new bearings in it. Inadequate fuel delivery will cause a lean condition, which can take out bearings. not saying that it has happened yet, just saying you should look at it"

I assume you mean from missfires pounding the bearings??? If so I think it would take a lot of this to cause bearing failure!
