Dwayne,
Try this. Once you pull the condom off, immediately put it on your PV. Now take 5-7 hits. If you cant inhale those all its ok, the idea is to create a vaccum inside the carto. Then pull the CE3 off the PV, mop any juice on the threads, wipe the CE3, reinstall everything. Don't know why but after taking a few hits, the leaking WILL stop.
