so a friends ego is leaking from the area below the bolt (think its the rammer area) near the back, above the grip, comes after working fine, and then being cleaned and lubed/oiled.. any help on this matter? all the O-rings were working before the clean, wwhich was followed to the manual (cotton swaps, and then oil/grease) so not sure what is causing this, and didnt want a new thread as the etek is very similar (08 ego)
