I just completed a pressurized smoke leak check on my intake manifold troubleshooting a high idle RPM problem.  Smoke check works very well!  No leaks except around the bearings that hold the throttle shaft in the Plenum.  Has anyone ever done a similar test?  Is it normal to have leakage around those bearings?

Really don't want to have to change them just to find out that wasn't the problem...
