Hi Paul,
This Air-Lock valve in the filler was also used on some Bedfords, like my QL. After owning it for about 30 years now it has never given any real trouble then about 3 years ago it started blowing water out of the cap intermittently and I removed the complete valve and checked it over. The spring had rust on it and was stopping full pressure of it onto the sleeve and sealing ring. I also found the screwed ring was not set correctly. Once I sorted this all out, and filled to the correct level (a bit lower than before) the blowing out stopped. Temp gauge only showed normal temp when water blew out, so doubt it was overheating.
Hope this is of some help.

regards, Richard
