Wanted to check tire pressure and couldn't get valve cap off. Got
pliers and it turned but never came off. Noticed the whole stem was
rotating. (Had probably gone once or twice around by the time I noticed
it.)

Is this permitted? Tire is not going flat, but should I get a new valve
anyhow?

Or fill the place where it meets the rim with glue? What glue?


I got the cap off with a sharp knife and added a little air, which has
not gotten out yet. (Can a metal cap get stuck on like this plastic
one did? That would be a lot harder to cut off.)
Micky, Micky, Micky - you get yourself into the finest pickles,
don't ypou???

The valve sem is a pull-in friction fit seal. It HAS to be able to
turn. Aslong as it isn't leaking, don't worry about it.

However, you DO need to be able to remove the cap - - - -

Metal caps are MUCH more likely to stick to the brass thread of the
stem. Cut the old cap off completely and replace it with a new plastic
one. Put a wee touch of silicone grease on the thread to help keep it
from sticking again. (grease - NOT sealer -- - -)

I DO use metal caps, myself - and I DO lube them. - but plastic will
be just fine for you and be less likely to catch you again. While yoiu
are at it, remove and lightly lubricate the others too.
