Minor, but annoying leak on 05 EGO

[Equinox]

I have an 05 Ego.
Its internals are all factory standard.

it does have a minor Air leak, if i take the bolt out i can hear it coming from the rammer.

i Have completely stripped and re-lubbed my Ego but i cannot seem to eliminate, or identify this damn leak!!!
I have changed the battery, and apart from the minor leak, it works fine!

Any theorys or ideas would be appreciated

sounds like one of the orings on the rammer has a nic on it.... either the biggest one on the rammer, or the small one on the long bit ie, the 2 outside ones and not the bumper one, cant be bothered finding a pic but hope that helps, probably just a tiny tear in one of those
