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?

Wait a minute. You snapped the cam because the oil pump was 180 out? Not likely. There is no "right" way to install the OP, as long as the tab lines up with the slot in the camshaft. The tab on the shaft is centered, and will fit 2 ways. Sounds to me like you used a T1 pump to "get better oil pressure". We can see how well THAT worked, huh?

Pound in a T4 pump upside down and you would get the same result. I've used type one pumps for years with never an issue, but then I have have always modified and installed them correctly. Is that a steel or AL cover? |

Did you also check the clearance on the drive part of the pump body and for cam bolt clearance? |
