yup, i got fed up and went to the autoparts store and picked up a little kit for like $5 that had 4 cores, the tool that takes em out, psi reader and some chromies and regular caps. As soon as i got back and i went to pull the core piece it was really loose for some reason, i took it out cleaned it up a lil then put it back in and made sure it was tight and filled the tire back up, i dont hear any air sneaking out but i will give it the overnight test at least and see where i stand. I do have one other question though, my first original tube that i had out was doing the same thing, when i pulled the core piece out it had a spring attached to the bottom of it, what is that for?
