Any ideas on how to fix it. Leaky valve on my stealth. I've loosened then tightened the valve core and it hasn't fixed the problem. Definitely the valve core leaking.
Fit a new valve core?
Are you sure it's the valve core-how do you know? Have you checked the valve housing base nut itself-I've managed to undo this by mistake-it certainly wakes you up !
The air leak gets worse when I loosen the core and less bad when I tighten it but doesn't stop entirely when it is fully tightened. I could try a new valve core. Cheap option!
Yep sounds like valve core and a trip to Halfords. Check the housing is nipped up though,just in case it's loose.
