Is that a Isky Cam? If so I have had at least, years ago before switching to using Comp Cams because of Iskys problem on them, two or more single bolt Isky BB cams have the dang pin work its way out and fall into the oil pan Let us know please BTW was the cam bolt loose when you took it apart? If so maybe that caused the breakage to satrt with, if it is broken in two parts
