All in all removing that one contributing factor out of the equation PROBABLY is good. I would of course still have the pickup checked since removing two factors is better!

If my thoughts are even remotely close to accurate I think that the small pieces can block the channels and galleries and then even a slight reduction in pressure or flow from a blocked pickup cause that particular part (usually a single bearing) to starve for oil.
This would be exacerbated by the heavy use on track which could force the small pieces even further into the channels while creating large swings in oil pressure.

Put it this way. If I was in your shoes I would still be cautious but knowing there was no more in the oil would be a relief.

Certainly plausible, and i hope your theory is correct for my own person self interest!

I am not going have my pick up checked, at least not yet. I am going to monitor via UOA and go from there. If it shows issues with bearings, i will decide at that time if i want to drop the pan, or full send until it blows. I only have a couple more months with the car this summer anyways. This will give me 6 winter months to see if suby will do anything about this.
