Huh. I had assumed that the dull alloy/tin colored material was the babbitt. The bearing has virtually none of that left, just the rust colored part. I do see the lube groove and it does make sense that if that is there(it gets cut into the babbitt after pouring, right?)then babbitt material must still be there. But why is it not the same as the other bearings? The rear bearing cap had a good bit of the alloy/tin colored material. What is the flaking alloy/tin material?
That said, yesterday we drug out the original engine, checked the bearing caps on it(they all "looked" fine), flipped it right side up on a wood engine cradle. Too tired to do any more on it.
Thanks!
