Xmetal,

It sounds like we are following similar paths. I didn't try a different weight oil, but I did try Ceratec on my last oil change. In fact, it is in the car right now and will be changed within the next 100 miles. Our mileage is about the same. I suspect I will find the same bearing wear that you have.

Did Lang have any opinion on Ceratec? My thought is that I know I need the bearings replaced and will be doing it soon. Since the most common failure is spun bearings, I was hoping if there was metal on metal contact (which clearly there is), it would slip over the Ceratec coating and not have enough friction to spin the bearing.

Now that you have new bearings, will you continue to use Ceratec? Since the WPC bearings have the slicker surface and the BE bearings have the coated surface, I don't know that it is necessary or helpful, but I suppose Ceratec has other benefits other than the bearing shells.

I was reading Loctite's literature the other day, and they have a product called 648. It may be that the Loctite would add too much thickness, but I wonder if anyone has ever tried adding that to the underside of the bearing shell where it interfaces with the rod.

When I do my rod bearing swap, I'll post photos and results, as well.
