i could not replicate the spurious pressure values seen by scott or jason on 10/12/2010, during morning runs with titania or hafnia during training.  
the oil pump was taken out for cleaning/repair/refill and in its place is a dry scroll pump.  the base pressure is 160mTorr at 5sccm flow, which may be a limit of the pump.  please continue to monitor the base pressure to see that it remains steady or if it keeps increasing.  
meanwhile, i'm calibrating a new pressure gauge in case that is the issue.
