Wow, interesting story... so you're telling me that the next time I'm feeling a little tight, I should just take a crow bar to my C997?
In response to the original topic, I find that, along with making sure that the caps are at the right tension, it is also essential that the O-rings are not worn out. There have been so many times when I have been having what seems to be an off day. Then I just pop in a new set of O-rings and everything magically opens up. I know it sounds completely nuts (many people have told me this

), but it really works. Maybe it's some kind of psychological thing...
