These lifters must have sat on a shelf for a long time, as the oil inside coagulated into crud that jammed up the lash adjuster and corroded some parts inside.
once cleaned up, they seem to be fine. I did need to replace the check valve ball with one from an old lifter due to pitting.
if you absolutely need lifters these will work with some cleanup, but if you have OEM ones, you're better off cleaning them.
