Slow Tire Leak
 

2000 Accord--found a near flat tire last night. Pumped it up and found that
the pressure dropped about 5 psi over night. Took the tire off, first thing
I checked was the stem with a bit of water---.lucky me-- It showed a small
leak. Tightened the stem and the leak stopped. Didn't want to trust it so
I just replaced the stem. Just curious, what the heck would cause the stem
to loosen up a bit? I've seen worn seats but never this type of problem.
