First observations from the engine teardown so far.

I could not believe how clean it was inside with no sludge, and the cylinder bores look and mic out good.

The crank pins mic out just in spec. haven't checked the main crank bearing journals yet.

The bad is, I found all connecting rod bearings badly flaking babbit.
See picture.

The two center main bearings were flaking as well, but not as bad.

I think that I caught things just in time to avoid a bad bearing failure.

Note the engine ran quiet, with great oil pressure before I removed it.
