Well, Elliott, I hate to say this, but I think you are going to need to
pull the engine and put it back on a stand.

Then you can slowly dismantle it and check very carefully for scoring,
cracks, etc... in a good light, on a stand, indoors, instead of lying
upside down with oil dripping in your face.
