XRAY - Model racing cars

Hello,
I have a weird phenomenon in my shocks absorbers (oil-Xray-Xb8e Ultimate).
They sparkle after use.

I clean them, normally filled (left to stand for the bubbles disappear), closes the cap with just a few mm rebound.
But after some packs (fifteen) it has a maximum bounce and when I open them, they are under pressure.
The membrane is properly and no traces of oil externally.

The video speaks for itself.

Bonjour,
J'ai un phénomène bizarre dans mes amortisseur (Xray-Xb8e-huile Ultimate).
Ils pétillent après utilisation.

Je les nettoie, remplit normalement (laisse reposer pour que les bulles disparaissent), ferme le bouchon avec juste quelques mm de rebond.
Mais après quelque packs (une quinzaine) ils présente un rebond maximum et quand je les ouvre, ils sont sous pression.
La membrane est bien mise et pas de trace d'huile extérieurement.

La vidéo parle d'elle même.

Hello

If you closing shocks right there should not be problem.
But there can be many thinks wrong. If closing is right it means it *** :-) *** from somewhere air witch go inside.
Check o-rings, check blader...

This is not normall.

What kind of compressions? On the car or seperately? I think if you exert big enough force quickly enough the damper might draw in air from the outside through the seals. I have seen something similar once before (bubbles out of nowhere) but I exerted a much bigger force than it would have had on the car.
Have you tested with another brand of oil?

No, i have not tested with another kind of oil.
It appeared, rolling on a small track, with many small holes and small bumps and large jumps.

I changed everything
Red and black o'rings
Oil, pistons
the Shock Rubber Membrane Bottom.

And it's the same...

I found the problem.
It was the white plastic washers to change.
