As for screwing the "valve thingy" back into the presta valve sleeve, is there a toll or trickfo doig this? I recall with a schrader valve, I used to have a metal valve cap with 2 notches on the end that allowed you to place over the tip of the valve and tighten or loosen it. Was wondering if this works on a Presta. ??
Here is a Presta Valve tool.

Here is what looks to be a better tool, not sure how well any of them work.
