if you have the camshaft you should be able to see if it was a casting
flaw - i had a driveshaft that snapped like that and was incredibly obvious
was a manufacturing defect, the dealer didnt even discuss it when he saw it
and just replaced it.

I wonder if someone has some reliably data concerning broken cam shaft on
diesel engine.
I have never seen a cam shaft to snap under normal load. The cam shaft on
my 1GM Yanmar broke in two pieces. Being a drop forged casting it requires
a
fantastic impact to break in two.
Unless it is from an original hair line crack at fabrication that was
not
detected at the time.
