excaliber 22 air rifle leaking

[cozzamec]

My excalibre leaked from the fill valve, it was audible tho, a friend at our club repaired it, not that hard and would have probably done it myself if I had any bloody time.

I am fairly sure these are very similar to the Webley Axsor. When I had a leak on my Axsor I missed the very small O ring inside the fill valve and eventually found that to be the problem. I didn't like doing it at the time but found it by submerging the front of the rifle in a dish of clean water and seeing exactly where the bubbles were coming from. There is an exploded diagram on Chambers website that shows the O ring OR068. It had dried out completely and was rock hard. Took some getting out as well if I remember correctly

It is very common to find the small O ring in the fill valve to be compressed and rock hard in these guns, it's difficult to remove, be careful not to damage the seal groove in the brass plunger when you remove the old hardened O ring.

Probably a bit of dust/dirt that got in your fill or exhaust valve and has now blown through then.
