Proform push rod problems

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.

That's what I was eluding to. The China stuff is never hardened correctly. They either wear down like butter, shatter like glass, or crumble like dirt clods.
