Many years ago I heard of an older gentleman on his way home from town in an old Chevy with poured bearings. One of the rods "Shelled" the babbit. He pulled her over to the side, got out his tools, carefully dropped the oil pan so as not to spill the oil, found the loose rod & took off the cap. He then proceded to cut the tounge (leather) out of his shoe, wrapped the journal with it, put the cap back on & proceded to drive her on home. Sometimes one just does what they have to do & leaves the Theories for others.
