Completed the upper chamber PM.  Chamber leak rate is about as it was before the PM (10 mT/min).  Backside He leak rate is a little high at 18 sccm (normally its around 10 sccm) even after replacing the lip seal oring. 
System should be OK to run for non-critical processes.  Please read Jim Mcvittie's emails for a more detailed account of the PM.
