If the #4 seized on it, IMO, check the align bore with a straight edge and
plasti-gauge each journal. I also use GM Break-In additive ($6 from the
local GM dealer). I haven't had a flat cam or bearing failure since I
started using this stuff. Just put it in the crankcase.

Can't be more "check everything" than that !!
May never know what the culprit was.
