The thrust bearing on the cam shaft lost one of its flanges? WTF? How does this happen? Anyone seen this? Maybe some extra metal from the failure got into my main bearing?

Your pump and your cam gear need modification/clearancing. Your case is not ruined.

QUOTE(McMark @ Jul 16 2013, 05:12 PM)  Your pump and your cam gear need modification/clearancing. Your case is not ruined. in looking at both your cam thrust bearing and your main crank bearings, I would not assume the case is not harmed. See if you can take some pictures of the ends of the case at the bearing locations for both ends of the crank and camshaft. Also, the bearing saddles. rich |
