Where are you hearing the leak from? Does it come out the front of the bolt as soon as you gas it up? how severe is the leak (how loud)? If you changed the external engine o-rings, did you lube the channels before you put the o-rings in? You need to use a lot of Dow 55 on those o-rings to get them to seal properly.
sorry forgot to write that
the leak is on the noid, the air comes from the hole directly by the manifold towards the LPR
its not that loud
