what is this part?

[jonbeatty]

I am rebuilding a RoW 3.2L 911 engine and while restoring the throttle body I took this part off. It appears to be a sensor of some kind but the two connections appear to be small vacuum lines. There is no electrical connection.
I suspect it is a one way valve that is thermally controlled?
I am trying to understand it so I can test it to verify it is still functional.

It is a thermo time switch that sends vacuum to the oil tank PCV.

Thx for the quick reply. I Googled thermal time switch and all I can find are ones with electrical contacts. Any chance you have a part number? Or, do you know how to test it?
Ok, someplace I think I have an old copy of PET so might have to find a way to read that CD. ;-)

I’m not sure exactly what that part is, but it sounds like it could be a thermal vacuum valve or a similar component involved in controlling vacuum flow based on temperature. I’d also love to know more about it and how to test its functionality, anyone have insights on this?
