00 v6 Purge valve test

[comet240]

hi I have a small EVAP leak.

the purge valve was stuck. so I bought a new one. installed it and it failed

I took it off and tested it by watching a video and they say sucking on the bottom it cant allow air going in or sucking cant move

this new one stuck too I taped it... and I guess ti came down.. you can blow through the bottom but if you suck on it slow nothing suck a little harder it seals..

but is this valve not supposed to allow air pushing in or sucking ...

or is this normal for this valve for this year?

Maybe go with and AC Delco part it might be a little more $$ but that would be a better control test. I wish I had insight of this sorry I don't.
