Advan valve stems are leaking?

[HIJACKER]

I have the blue Advan metal valve stems. I noticed that when I remove the screw on cap, 2 out of 4 of my valve stems have a slow leak. They appear to be the screw in type.

Can I replace them with any aftermarket stainless steel screw on valve stem? If so, what size do I need or is there any recommendations?

It could just be that the valve stem core just needs to be tightened a little more. Use a valve stem core tool to tighten it.
Next step would be to replace the cores.

Any tire shop should be able to help or fix these issues for you.

My old Work wheels had custom valve stems, but used standard valve cores, so I would imagine that the Advans also use standard valve cores.

Bingo. This is exactly what the problem was. I've never had this problem before, so this was news to me! I picked up a tool, tightened them, problem solved!
