Cam wiped out, what the hell did I do wrong?!?!?

Sorry for your luck I know how you feel,I've given up on flat hyd.cams rollers from now on,roller blocks or retro rollers only,seems just about everybody is loosing flat cams,I don't think it's the oil's fault I think the quality of the cams and lifters is crap.I've even started to run the eastwood additive just for piece of mind.
