Today we replaced the decomposing vibration isolators, vented the y-mid turbo and removed the motor electrical feed through flange that had the 10-5 torr*L/sec leak -> The O-ring was dirty with lots of particulate but otherwise typical -> We cleaned the sealing surfaces of the mating flanges and installed a new O-ring that we had "slathered" with Krytox - > Pumped volume with QDP80 for 90 minutes followed by full spin up and spin-down of the turbo -> we then isolated the turbo volume from the foreline and observed the pressure rate of rise -> it appears that we reduced the leak but it is not clear if the pressure rise observed is due to a reduced air leak, wet surface out gassing or a combination of both -> the observed pressure after 24 hours will help answer this
