You need to do that again with some revs to tell if if is a rod or a valve. But most likely a rod and it sounds like it is chewing up that bearing.

Get an oil analysis and it will tell you what is happening and if the bearing is bad or something else.

Compression test would tell you if it was a bad valve. If you have done that already the it is a rod bearing and it's chewing up the crank.

There is a post about someone selling new motors on here.

Sell the SC and get the motor. Replace it and the you have something to drive.
