    Ive just filled up with water, the filler cap came of ok (push in twist anti clockwise ) but wont go back on,?

    It just turns and wont grip?, Im currently try the "soke it in boiling" water trick, I did it once for about 10 mins and it didnt work, should I have left it longer? or is it knaXXerd. If I need to replace it, would it be better to repalce the whole unit or just get a new cap, there does not seem to be any damage to either part. It does seem to comprese ok, the lock does turn with the key.

    Are you sure it hasn't locked, tried it with key in both positions?
    If you need to replace it you can swap the lock barrel over

    Ive read your earler posts suggesting that so I did try it with the key position both ways, I soaked it twice but to no avail. the only thing I didnt do was wipe it round with silicon spray, Ive got some wd40 will that do?

    there seems to be a lot of very simular caps about, olearys have one thats universal? any ideas if there any good

    Silicon it the right thing to use. Its very odd that it spins freely as that would indicate it is either locked or broken if unlocked.
    Have you a picture of it?

    To be honest it can be a bit of a phaff some times but usually its because the you're trying fit it with it locked.

    BTW boiling water is to free a cap that's seized . Yours has not seized just the opposite

    Should only be able to twist it when locked. It should all turn together when unlocked.

    You actually have the opposite issue to the usual fault where it seizes together so locking it has no effect.
