I used them to check pressure at the base. I had a screw up and ran the engine with the crank-case ventilation sealed. Oil started to discharge from the turbo as a result.
I heard the hiss from the crank-case before the turbo started discharging oil, so I opened the oil fill cap to vent the engine. After that, the turbo passing oil didn't seem to stop passing. I talk to Zach about it, made all the routine checks (oil supply, oil return), then pulled the turbo and sent it to him. Turbo checked out OK.
I think I just got ahead of myself on the whole thing.
