Question Tyre/Tube Valve Issues

Can you damage a valve stem? I have noticed a slow leak through the valve on my rear tyre so I replaced it with a new valve but that leaked also. When I noticed the flat the tube/tyre had spun on the rim and the valve was sticking out on a bit of an angle. If it is damaged does that mean my good ultra heavy duty tube with no holes in it is a throw away item? Whats the crack?

Please help...............I'm a bogan in crisis.

lerroy if the tube spins inside the tyre , and the valve is on a really bad angle coming threw the rim. It can rip the whole valve out of of the tube.
I have had one in the past that was on a nervously looking angle and when i went to try and straighten it . Wam that shitty psssssss sound and it was ripped ( only a small rip) where the valve is located on the tube

so chances are your new tube is going to be f...ed !!!!
doesnt that piss ya the joys of dirt biken

If the valve is ripped from the tube its ratshit you'll have to put a new tube in theres nothing you can do to fix it

Thanks for your help Wayne and Moo but I don't think my valve stem as ripped away from the tube as the leak is coming out of the valve stem. My only guess is that the valve has not seated in the valve stem properly and air is getting past the inside thread. Is this possible? Or could I have tried two faulty valves?

Yes, you can damage the valve stem & if it is damaged it is a throw away.

The thread on the valve stem may be damaged. There is a valve tool you can buy which can clean this out. Try another valve first and if that doesn't work get hold of one of these tools and clean the thread up.

Also if you rip the valve stem off it can be repaired. Rema Tip Top make a patch which includes the valve stem. It isn't as strong as original but does work.

I have included photo's of both. You can buy the tool at places like Repco and it is handy as it can remove valves, and clean up both the interior and exterior threads on the stem. It is also useful for pulling the stem through the rim.
