Air leak from valve stem with tubeless setup
#1
I have a mountain bike with Mavic tubeless ready wheels. I went to change the tires and the front wheel is leaking air from the stem (see pics). A bike repair guy told me to replace the stem but it still leaks in the same spot. I cleaned the old sealant from around the stem. I shook the tire to encourage the sealant to plug the leaks and it just came oozing out. I waited overnight to see if maybe the sealant just needed some time to take hold.. still leaking.

Any ideas of what I can do to fix it?

Can you put a tube in it? That may he the cheapest solution.

Is your rim drilled for shrader? if so flip your nut around on your valve. Tighten the crap out of it, finger tight may not be enough, snug it up with pliers

I took the tire off to clean and retry and saw some damage to the liner (Imgur). I'll use a tube until I get a replacement strip.
