The only thing I might have been concerned about would be the area where to top oil seal rides. It seems kind of pitted. I’d have been a little concerned about an oil leak in that area, even with a new seal. Anyway, it’s water under the bridge now, and I am glad it runs well for you!
I see this also.. But, it is hard to know if the upper seal actually rides there or not. Now looking at one of your other pictures showing the top of the crank, and the upper bearing sitting along side of it….. I see an oring on that bearing… Perhaps that is the lower bearing.
Members have shown how to pressurize the crankcase slightly and look for leaks in this area. But, the deceiving thing about this test on this engine is that you will see leakage between the upper bearing case and the crankcase because no oring is used. So, it can be very tricky to determine if the leak is coming through the seal lip/crank, or the bearing case/crankcase.
The only other possibility is to use one of those tools to remove the upper bearing without pulling the powerhead apart. Before removing it, make a good note of where it sits in the bearing case. There is a chance that you could install the seal just a little bit lower, or perhaps higher in the bearing case so that it is not rubbing on the pitted portion of the crank.
