More dumb questions - I was in poking around thinking "man those last couple of pipes are going to be a pain to get off to put those O-Rings in" and started tugging on other stuff I have no business messing with. I noticed that one of the lifters appears to have a good amount of play in it. <img src="/forums/images/graemlins/scared.gif" alt="" /> Here's the video.

Is this a problem, or am I having a fit of Smiley-esque paranoia here? If it's not right (none of the others are that loose) is it worth me doing something about, or should I (could I) write it off as old age and ignore it. <img src="/forums/images/graemlins/zombie.gif" alt="" />
