I see that #42 cam's were tin coated and #49 cam's are chilled cast iron. I'm guessing that MB might have detected a defective manufacturing process and changed along the way to extend the life of the cam's.

My second cam wore out different lobes than the first cam, so I'm guessing that it's not my oil tree.

Thanks,
