FX FX Impakt MK1 leakage...again

[SWEJaeger]

Am I missing something. Have recently fixed 3 leakages. Regulator and both 2x1 orings in the cavity plugs.

But now 1week later its leaking again. Approx. 1-3bar/hour so its not super small.

But I cant find it. I have checked all these places 2-3 times now with leakage spray/foam.

Any ideas? don't know what to do next except complete re-sealing except the ones I already changed.
But How can I not spot a leakage this big.

Tried a balloon on the barrel for 2 hours but nothing, unless it leaks into the shroud and out somewhere else?

IF you re-seal replace ALL o-rings, even the ones you just changed. Start at ground zero with all new rings. You'll be glad you did.

Yes probably its time to change everything.

But there is and itch in my brain. Its not logical. Why do I not find the leakage when checking all places it could leak from.
Its like the air is vanishing through the steel. Even tried again with a friend next to me to judge whether Im crazy or not.

Thinking vape pen and aquarium. That would show were its leaking
