Actually the two holes I'm talking about are up in a chamber directly under the inner intake "slope". They are behind the rear needle bearings that the rear of the rotors ride in. They are there to facility pushing out the needle bearings during a rebuild. I'm wondering if the bearings allow pressurized air through them that would escape thru those holes to atmosphere. I have to get a look a the gasket and an intake manifold to see if that chamber gets sealed off. In the pic you can see the chamber above the air exit (because the case is on end). That is the chamber that the holes are in.
Just wondering if I'm going to have to take it into consideration when I make the bottom plate. That case is just riddled with passages and holes. I have to investigate every opening to make sure everything is sealed in the end.
