A Stuck Valve Cap

[Wester]

How do you free a stuck valve cap ?

 

[Dogtrousers]

With a pair - or possibly two pairs - of pliers, I guess. I don't recall ever having had that problem.

How do you free a stuck valve cap ?

I assume its a metal one? but yes pliers.

lithium grease when the new metal one goes back on

If is not a metal one then carefully cut off with Stanley knife.

I’m assuming it’s a Schräder (car type)? If so, and you decide to go at it with some pliers, it might be worth holding the valve body itself with something non-destructive to prevent it from twisting and possibly tearing the tube.

I think this is the first time I have heard of this particular problem.
A pair of pliers, or maybe another to hold the valve stem whilst rotating the offending cap will do the job in seconds

How often should I lube my chain ?

Did you get an answer to this @Wester? And how often are you oiling your chain now?

How do you free a stuck valve cap ?

If you neatly cut the end off (presta valve) you can use a pump designed for a schrader one.

Or you can snip the end off and then put a little hole under the valve and pop a new Shrader

valve in, followed by a patch.

Are those patches of rust (edit: next to the second use of 'valve')?
And @Wester was ahead of the curve with this question too (2 March 2020, 16 pages):

What are the chances of a cyclist contacting Coronavirus ? as it is a respiratory infection I guess and I am only guessing it must be slim as most cyclists are always blowing hard so you blow out any thing bad that you breathe in

 

[Gillstay]

Not sure what you mean !

If you're using a pair of pliers on the valve body and cap, use a piece of old innertube on both.
They can reduce the amount of pressure applied to the valve body and cap in freeing them.

And a new car as well, just in case valve cap sieze disease is infectious.

Blow torch. Heat it gently until glowing dull cherry red then simply twist off with the fingers.......
