Hey everyone,

We are fiddling with odds and ends and one of the things we are working on is eliminating a bit of a clickity-click that we have in the engine. We do not think it's a valve noise. Instead, we think the lifters are clicking. We pulled out the lifters and found that the little "button" under and inside every single one will not move. You can't press it in at all. We have noticed that this is not all that uncommon. We also have read that we should be able to press that "button" in on a healthy lifter. We are putting in a new set of lifters, but I wanted to take it to the group and see if there is anything we should know about this operation.

So, is there anything we are and/or could be missing?

Thanks!
