The rocker just sits there unsecured by anything but hydraulic pressure in the lifter, if the lifter bleeds down they fall off, the lobe hits em and can break all kinds of thing or not harm a thing. Once one falls off the rest are liely to do the same and just replacing them is not enough it just starts sno-balling from there.
