Proform push rod problems

I'd agree with this statement most of the time, but ProForm, ProComp, Speedmaster, PRW products are piss poor quality junk. This failure is almost certainly a materials and heat treating issue.
At this point I wouldn't argue that the cup end may have been an oiling problem but the ball is not. More than enough oil sitting on top of the lifter. I can dig it out of the trash but all you going to see is a tube with no end. The ball just crumbled and fell off.
