Hi All,
OK, I cracked the case today, and have some very interesting clues, but no smoking gun. I have about 80 pics, but I'll only post the most relevant ones. First, The shaft to the oil pump was sheared. Did this happen post rod-throw or was it the cause?
Second, one of the rod blot nut was unscrewed, not sheared or stripped. Did it unscrew first, or after the bearing failed and the big end overheated?
the rod bearing was gone, ground to smithereens. The bearing surfaces were heated, but all the other bearing looked OK.
and from the rod cap, it's clear one bolt let go before the other.
From my uneducated view, I would think the rod bolt stretched or the nut started to come loose, and everything else followed. I did use red lock tight and a calibrated torque wrench.

Any Opinions?
Thanks,
