OK fellas,
Did not want to start WWIII was just curious as Walt mentioned it was not uncommon.
It is a repair I am yet to see here so was milking the forum for more specific information.
Just finished a cam shaft on a 33M and can see why so many of these ACR's end up in the bottom of the sump.
Biggest problem was missing metal.
When I was sure all of the broken pieces were out washed & dried the debris but it was 60 grm lighter than the new one.
Buggered if I could find any more metal so it is back together now, so time will tell.
