No leakage, the O ring left from cutting the bladder sits against the plastic cap and shock body.
Paul if you try it the best way to bleed them is to fill with oil, screw the cap down until it starts to go tight then unscrew it half a turn or so and push the shock shaft all the way in, and then tighten the cap whilst holding the shaft in. It should make the car better over small bumps and ripples.
