I have a question about the egr system in my 81 300d

I investigated removing the 3/2 box connections from my 81 300d this weekend as i've read about here, but was confounded on what to take out and plug back in.

So instead I pulled the cap and replaced or repaired the small hoses inside that were old or cracked (2 were bad). And as expected she shift much much better.

It did get me thinking (not always a good thing) about the egr valve that has a ball bearing in the vacuum line from the 3/2 box, and I was wondering.......

is it closed when there is no vacuum signal? or open?

The EGR valve should be closed with no vacuum signal. However, it is a good idea to remove and check for carbon build-up on the valve seat that would prevent it from closing all the way.
