Thanks guys. It's not that they leak like the stock ZX5 shocks did, but they start "sweating" oil at the seals rather fast compared to the Losi schocks. They are OK for 20 runs or so, then i replace the O-rings.
I use green slime and unobtanium shafts. I heard somewhere you have to lightly sand the white plastic spacers since they put to much pressure on the o-rings. Other sources on the other hand say you have shim the seals to put more pressure on the o-rings.
