A few months ago we had a tire on my daughter's car that had a slow leak, turns out it was a nail and the tire was repaired. Over the past couple of months I've been monitoring it as it seemed to still leak down but it would take quite a long time. I thought maybe it was due to the temperature changes or that it needed to be looked at again. Today I put some air in the tire and decided to put a little dish soap on the valve stem just for kicks and, low and behold the thing started blowing bubbles, lol. So, I got out my trusty valve stem wrench, (had it for years when the kids were little and we had bicycles, yet never used it), and tightened up the valve stem, yep, it was a bit loose. Now no more bubbles. Yay!!!
Note, in one pic you see bubbles in the soap but that was from squirting the soap out of the bottle, it isn't leaking anymore.
