More progress has been made, dad went ahead and pulled the pistons/rods and crank.
All of the rod bearings look fine, a little scuffed from some of the trash in the oil but no copper is showing at all. However the Crank bearings on the front and rear of the motor are trash and even more obvious than the cam bearing was
. The top of the front crank bearing and the bottom of the rear crank bearing are clearly copper colored, the middle two bearings are still completely usable. it seems that the crank was misaligned in the block and/or the Balance shaft and the timing chain tensioner really do put a good deal of stress on the bearings.
The pistons are not usable anymore, all of them are scuffed on one side, and the #6 is scoffed on both sides. They had some play inside the cylinder wall. The bore is incorrect or off, if this block was to be reused it would certainly need to be bored over. Also requiring new pistons. But this block will likely be dumped unless someone else wants it (Highly Doubtful).
Dad has all the pictures on his computer, I'll get those up tomorrow afternoon to show/explain in a little more detail of the findings.
